IGO for TI

After noticing that there is currently no Go program for the TI 83 (Plus) that fulfills my expectations I decided to write one on my own. Nontheless I appreciate the efforts that others put in writing their programs. Since I'm not very creative in inventing names I just called it "IGO".

Overview

"IGO" enables you to play a game of Go on a 9x9 board using your Texas Instruments TI 83 Plus calculator.

It is written in Assembly.

Current Features

• Players can pass
• Players can resign
• Suicide is prevented
• Ko rule is implemented
• Captured stones are removed automatically
• Number of captured stones for both players is displayed
• Current coordinates are displayed
• Display whose turn it is
• After two consecutive passes one player can remove dead stones. The result is calculated automatically.
• Playing over unit to unit link cable is supported

According to the tests I have made so far these features work fine but of course there are most likely a lot of bugs I haven't found yet so I rely on your bug reports.

Bugs

-For some reason, gets syntax error when running under ASM.

Keyboard Layout

"UP", "DOWN", "LEFT", RIGHT" - Move cursor
"ENTER" - Select menu option/Place stone/Remove dead stone
"CLEAR" - Exit game
"+" - Pass
"-" - Resign
"*" - Calculate result

How to run it

"IGO" doesn't use any shell like ION or MirageOS so you just run it using Asm(prgmIGO). Asm( can be found under 2nd - CATALOG.

Download

There are two versions available. The only difference is the language of the on screen text. Be aware that these programs work only on a TI 83 Plus or TI 83 Plus Silver Edition. There is no version for the "normal" TI 83 yet.

Plans for future additions

• Komi
• Handicap
• Tsumegos
• Load/Save games
• Transfer games from/to the PC
• Replay games
• Port to TI 83
• Make it available to MirageOS

Long term plans

• 19x19 support with two display modes
  • Display the whole board - Stones will be quite small because of the limited resolution
  • Display only a part of the board similar to current 9x9 size and enable user to scroll
• Write a version for TI 89 - I'm not that sure yet if this will happen because I don't even own one at the moment.

Suggestions

If you have a suggestion for a new feature or improvment of an existing one don't hesistate to add it here.

Also I welcome any other kind of feedback - I would like to hear your opinion about the program.
