Moving SGF files between your PC
and PalmOS® device
To make best use of the Memo Pad, it is a good idea to
have all your SGF files in their own Memo Pad category
"SGF", say. This will help you to keep them separated from other
memos, and will reduce sort/search times if you have
many other memos.
To create a new category of Memo in the Palm Desktop
select Tools/ Categories/ New, and enter "SGF". You
will need to do this once only.
Memos are normally copied to your Palm Desktop,
whenever you use HotSync®.
Using Palm Desktop to store games
If you have many SGF records, and do not want to keep
them all on the PalmOS® device at the same time, then you can
use the Palm Desktop to achieve this efficiently.
Once only, in Palm Desktop, do "Tools/ Users .../ New ...",
and then add a new user called "SGF Archive", say. If
your normal, PalmOS® device, username is "PP User", then you
can move/copy multiple Memo Pad entries between "PP User" and
"SGF Archive", by using simple drag-and drop in Palm Desktop.
This is much easier than moving to/from Windows itself.
Perhaps you can keep all your SGF records in "SGF Archive",
and just the current ones in "PP User". You will not need to use
the "SGF Archive" user in any other way.
Adding files to your PalmOS® device
To transfer SGF game records from your PC to the PalmOS® device,
you have first to transfer them to the Palm Desktop,
before doing a HotSync®.
In the Palm Desktop, select the Memo Pad facility;
make sure that you have chosen the "SGF" category at the top,
then press "New...", and copy the contents of the SGF file
to the window at right.
If you use Linux you can install several files simultaneously,
using install-memo thus:
install-memo -c SGF /dev/pilot *.sgf
For more details, please refer to the man page for install.
There are no standard tools for moving several files
simultaneously from your Windows PC to the PalmOS® device,
or back. However, if you use a Windows PC (Windows 98/ ME/
2000/ NT/ XP) then
there are now tools to help you transfer multiple files in
either direction (PC <> Palm). These are
MPAtoSGF. They were written by
Martin Schmidt, but have not been tested by us. Please note
that both programs work only with memos < 4Kb in size.
Removing game-records from the
Obviously, you can remove single records, either from the PalmOS® device
(within Memo Pad), or from the Palm Desktop.
If you are in PilotGOne, and you want to delete the current game record,
you can use
Edit This Var.
If you want to
delete many game-records simultaneously then you might be able to
do something like this:
- If this helps, first sort them into the appropriate order on your
- Do a HotSync® to get your (maybe re-ordered) memos transferred to the
- Within your Palm Desktop, do a multiple Select,
followed by a Delete.
- Do a HotSync® again.
There is a (freeware) tool Mass Transit that makes it
easier to delete multiple memos. It also lets you move,
simultaneously, a number of selected memos to another
category could be useful. If you are patient, Mass Transit
can be downloaded
Alternatively go to
Mass Transit's Home Page splatbang. Please tell us your experience.
PilotGOne will happily work with, and create,
memos that are longer than
the 4 kb limit that MemoPad seems to impose. It is perfectly possible
to view and delete stuff from these with MemoPad, but not to extend
them. For PilotGOne, there is a practical limit of 64 kb, and
some files larger than 4 kb may not work properly.
The Unix tools will let you download large SGF games as one
Recent versions (v3.0, and later) of the
Windows Palm Desktop can be used automatically to split
large files into 4 Kb chunks, putting a part number in the First
Line of each chunk.
You will need to prepare the SGF file for later use: edit
the file using a text editor such as Notepad, to create
a meaningful "First Line" e.g. Insert the text
"Joseki_Dictionary" on a line of its own at the beginning
of the SGF file.
When in the Palm Desktop, Select the "Memo" icon; make sure
that the Category is "SGF"; click on "File" / "Import...";
change to the directory where the SGF file is; (probably
best to select "Files of Type: Text"); now type the name
of the file in the "File name" field, and then click on
the "Import" button at right.
This will break up the SGF file into several memos with first
lines like "Joseki_Dictionary 1", "Joseki_Dictionary 2",
PilotGOne will now spot when you open a game whose first
line ends in " 1", " 2", etc note the space before the
"1", etc and join the chunks back together again,
although you have to have enough memory free to do this,
and it is a little slow. At present, there may be problems
when Hot Syncing large memos see
Ideas for future features.
Some Odds and Ends
- [worst bug] In Game view, opening the Options menu
(or simply touching the Menu Bar!) crashes some Handspring
handhelds (Visor and Platinum) running PalmOS® 3.5H1.2
also seen on 3.5H1.5, and Handspring Visor Neo, running
PalmOS® 3.5.2H3 (thanks to Kris J. Nuttycombe).
The problem has been reported to Handspring we are waiting for
Please tell us if you have had this problem on other devices.
- In Listview, do Menu/ Options/ Board Preferences ... (or
- In Board View, either use the "/P" shortcut directly, to
get the board preferences, or tap "Done" to get to Listview,
and then do as above.
- In view mode, it displays the score unnecessarily, and
incompletely, at end of game, if dead group info has
previously been saved.
- Score Mode: error in
counting points in some sekis, and some other positions, rarely.
- Score Mode: display of count may be truncated.
- Possible problem
following change of colour to play, and then using "undo".
- When you are not at the end of the game, and you do
say, and then choose the option "Replace last
NN stones", then sometimes -- maybe only if you have
variations -- the value of "NN" that is reported is wrong.
We have reports that sometimes you are not even given a
choice, even when you should be!
- Comments greater than 1024 characters are
- Some (merged) memos that are bigger than 4 kb will not Hot Sync properly.
- Limited recording, and display, of
- Triangle and square marks are too big for 5x5 boards.
SGF (Smart Game Format) is a well-defined standard, occasionally it has
been interpreted slightly differently by different programmers.
This may cause problems with game records produced by other programs
e.g. there was once a problem, for PilotGOne, with some records produced
by My Go Tutor. This problem has now been fixed in PilotGOne. Please
report any new problems that you find.
Some things that you may consider limitations may be included in
Ideas for future features.
Ideas for future features
This is a wish-list mainly for the benefit of (potential) developers.
Warning: do not get too excited some of these may never be
implemented! ... unless you do it :-)
The categories below are not completely distinct.
- Suicide ban (not illegal in all rulesets, so will be optional).
- Ko retake ban unlikely to be implemented before 2010! :-)
- Area (Ing/Chinese) scoring.
- More intelligent scoring mark stones dead if they can "see"
other (same colour) dead stones; do not count as territory either necessary
internal reinforcement (te-iri) points (especially chains with only
one internal liberty), or false-eyes in seki (shared life).
- "Protect" (with "\") special characters e.g. "." and "]" in
Game properties (as already done in Comments). Don't display "\".
- Implement creation of SGF's Nodename, and PL (change player),
properties. Consider effect of, and on,
black/white play, as well as
Allow the creation, and use, of
empty variations especially
useful in collections of problems e.g.
(;C[Problem 1. W to play.]AW[aa][ab][ac][AB[de][df]PL[W])
(;C[Problem 2. B to play.]AW[aa]...AB[bc]...PL[B])
(Thanks to Rodney Topor)
- Forbid creation of upper case marks they are displayed as
- Cope with setup in root node of SGF record emails 2001-09-04.
Ease of Use
- Allow re-map of pageUp and pageDn buttons to existing functions.
- More functions re-mappable (using soft and hard buttons).
- Allow use of graffiti area for some other functions could
dispense with stylus almost altogether?
- Extend "undo" especially with Goto Move in view mode (requires
program to remember more of what user has done).
- Skip to next comment/annotation feature.
- Improve use of Add Black, and Add White to delete an
"AddBlack", do another "AddBlack" at that point.
- Goto Move Number ... - useful when working with published
game records, and/or stone was captured.
- Better handling of variations (delete, move, etc.).
- More features for working with collections of problems or
games, and joseki dictionaries. Possibly (optionally) show
the number (or, if SGF allows, a description) of the
currently displayed problem.
- Better variation handling for game records not created by PilotGOne.
(Rodney Topor 2002/07/12)
- Enable/disable Goto Begin/End Prev/Next Var if "^" and "v" gadgets
are not present?
- Add the following commands to the "Goto..." panel:
- Go to the previous position. This is defined as being the
last position visited by a "Goto..." command. Not all the tree
traversal commands have a simple inverse, and occasionally one
wants simply to return to the last position visited.
- To take this idea further, maintain a list of the last (max)
"n" positions visited, and be able to rewind (and then go
forward again!) through the list. Users are used to this
with web-browsers; a similar function would suffice.
- Go to move "n". This could be simply move number "n" in
the whole game. However, a "Goto move n in this variation"
command might also have some benefit!
Managing Records, Sorting and Searching
- [?] Detect newly uploaded SGF memos optionally, automatically sort
- Delete game feature in PilotGOne now need both PilotGOne
- Database of player info. Reduces time/errors in entering player info.
Especially useful for common/difficult names. Idea from Nishikawara Youichi, and
- [?] Develop improved methods for handling memos > 4kb. These occur in heavily
commented game records, joseki dictionaries and problem sets. Perhaps allow
multi-memo handling (especially for memos > 64kb). This will make synchronization
Permit merge and un-merge of memos? Probably always keep memos < 4kb
no (re)synchronization problems. (Todd Heidenreich and Rodney Topor).
Perhaps just have a better way of keeping multiple memos linked,
- Have Game Record Categories with indexed entries: remember index
of last one visited in each. Helps manage records.
- Distinguish PilotGOne-created First Lines from others. Allow "Clear
first lines generated by PilotGOne".
- Create SGF category (if necessary), and make it default for PilotGOne, on first load.
- Rotate display (/game record?) by 90/180/270 degrees :
recorder at side of board; sharing game record with opponent;
- (Mirror) reflect display (/game record?); also swap colours on
display (/game record?) : Joseki Dictionaries.
- Save rotated/reflected/inverted game record, optionally. see above
- Allow auto-creation of selected default first line for all records
without one yet.
- Duplicate Game Record --
make another copy of a game record enhances SGF editing
capability. Now have to use Memo Pad, with error-prone (possibly
multiple) cut-and-paste. Protect original game record.
Useful for problem collections.
- Delete other vars. This command would delete all variations
following the most recent branch node other than the current variation.
The command is useful if you have just tentatively explored several
game, joseki or problem variations, returned to the main line, and wish
to delete the tentative variations from the SGF memo, without having to
delete them individually. This may be dangerous.
Delete following moves. This command would delete all nodes following
the current node. The command is useful in similar situations. It
complements the "Delete this var" command which would delete the current
and possibly previous nodes as well, which may not be desired.
- Edit first line directly from PilotGOne (done indirectly now).
- Delete This Var: display messages when user tries to use it, and it is
- ? If in score mode, and user changes to any other mode, prompt
to suggest "Save dead group info" first?
- Auto Replay feature
(with Pause and StepBack) in view mode.
- Auto-respond feature:
Plays "opponent's" moves with Problem sets and Joseki
Dictionaries. At present, we can (partially) mimic this in "guess"
mode, if we have records of the form:
(... setup ...;AB[...]AW[...]PL[B](;B[aa]AW[bb];B[cc]AW[dd])(;...))
However, this does not work with normal records, and cannot cope with
multiple possible White/"opponent" moves.
Obviously, it also does not allow us to guess the opponent moves.
- Support for all relevant Sony Clie features.
- Add more support for colour. If you want this badly, perhaps offer to buy
a colour device for one of the developers ? :-)
- Warning if PilotGOne tries to create game with Komi < 0, or Komi > 10. Currently, if negative it is set to zero.
- Warning if Handicap not zero, and Komi not either zero or 0.5.
- (Optional/Extra?) Comment mini-window!
- Gain two more spaces for gadgets -- leave out "B" and "W", just keep number of
prisoners -- maybe: normal (white), and reverse video (black)
- Documentation: expandable/contractible contents list on web page.
Some Sources of SGF Files
Sorry, some of the larger SGF files will not be very useful
until we have better handling of memos which are bigger
than 4 Kb.
- Check out
in the section "Go: Sources of Game Records - SGF, UGZ, ...".
- A useful list of SGF collections on
page (when it is available)
- Go Games On Disk collections
GoGoD may be bought via
het Paard and
- GoBase has lots of
- Go Teaching Ladder --
- A collection
of Classical Go problems from Ulrich Goertz these may need
to be split.
- Kogo Joseki collection
a single, approx 400 kb, SGF file will need to be split ... If you do
this, then please tell us.
- Games played on the IGS look in
- Use FTP to Download a compressed (Unix) "shell" archive of
which has deeply buried within it a number of files (sizes are:
91.5, 83.3, 81.7, 12.4, 1.8 kb), some of which will need to be split
before they can be used. You will need
a tool that copes with ZIP files,
to get at the contents.
If you want to keep up-to-date with changes to PilotGOne, or want to
share ideas about PilotGOne with other users, or want to help with
the development of the program, then you can subscribe to an
appropriate mailing list:
You can subscribe by emailing
send an email to email@example.com
- pilotgone-announce: pilotgone palmos go recorder announcements
- pilotgone-user: pilotgone palmos go recorder user discussion
- pilotgone-dev: pilotgone palmos go recorder developer discussion
As messages are sent they will be added to
an archive of
posted messages (new place). Anyone can read the archived messages you
do not have to be a subscriber to a list to do so.
These mailing lists use EZMLM (EZ Mailing List Manager).
To find out what this offers you, check out the
the EZMLM/IDX MAILING LIST MANAGER, or if this does not work,
then a duplicate
copy of the EZMAN-0.32: EZMLM/IDX USER'S MANUAL
There are many programs that can unpack "ZIP" files. You
may want to use one of these:
There are many tools, available on host computers (especially PCs), for
splitting files into smaller pieces. Perhaps find a freeware, or
shareware, tool that suits you (not many features needed) by searching
for "file split" at
or even cast the net wider by searching with
or your favourite search-engine. Maybe look for "split60i.zip" or "chop31.zip".
An easy way of helping might be to share in the discussion on
one of the
PilotGOne Mailing lists,
especially the pilotgone-dev mailing list.
If you are a programmer, who is happy (to start) working in the
very good development environment SDK 4.0 (supplied free by Palm),
then check out the
Ideas for future features
to find a problem to solve, and then look at the
sources that are freely available
maybe check with the pilotgone-dev mailing list, in case
someone else is already working on it?
We are also looking for some general tools for PalmOS®
and/or Windows. Some things that would be helpful are:
- Creating a First Line from the filename on the host computer.
This is already possible with the Linux tool. It would be helpful
to have something for a PC and/or a Mac. Ideally this would be a
free-standing executable, but a Perl script could be useful.
A number of people have been involved in various ways in bringing
PilotGOne to its present state.
1998 - today: Brian Brunswick the originator. In 1998 he worked
on the first versions alone. He is still actively involved
in the development, and is also responsible for running
the web site and the mailing lists.
early 2000 - today: Sylvain Soliman: coding (first published in Nov
2000); co-ordinating function; beta-testing.
late 2000 - today: Harry Fearnley: documentation (first
published April 2001); beta testing.
In early 2001, PilotGOne was placed under the
Gnu GPL licence.
Later in 2001, some mailing lists were created for PilotGOne users,
and (potential) developers, to share ideas.
Throughout the years, a number of people have kindly reported
problems that they found with PilotGOne sometimes they have
done extensive tests. Others have written
with suggestions for additions, and improvements that they
would like to see -- some of these have been very detailed
specifications. Since early 2001, several others have helped
with Beta testing, or have contributed specific bits of code.
Sometimes, these people have been mentioned, by name, in the
"Change History", sometimes not sorry!
Individual contributors include (in alphabetical order of
Nishikawara Youichi (
"The Nose who Knows".
Please let us know of any omissions.
We have also used the free tools:
Palm Inc's PalmOS Software Development Kit,
and PalmOS Emulator (POSE) -- especially for the screenshots;
Xenu Link Sleuth
to check the links in the web pages;
to create the animated GIF image;
JASC Software's shareware version 3.11
of Paint Shop Pro, for compressing the screenshot images, and converting
from BMP to GIF and PNG format.
Currently we use: Palm Pilot Professional, Palm IIIe,
Handspring Visor Prism, Handspring Platinum, Sony Clie
There is a Japanese variant of an earlier version (0.7.0?) of
PilotGOne. It is called
and there is an associated eGroups Discussion Group
igo-palm in Japanese.
Many thanks to Nishikawara Youichi for this version. There is also a beta version -- probably based on PilotGOne 0.8.0.
