Acknowledgements

Uses code from Skippy’s psp libraries, pspsdk, mikmod, libmad, libpng and PSPMediaCenter. Thanks to everyone involved in those projects.

Images were designed by Stadi Thompson. Extra big thanks to him for contacting me and volunteering to make them.

Pieces

You can get more images for pieces here. If you create your own sets, please share them there.

User Interface

Select piece to move using arrows and then press x. Select destination square using arrows then press x.

Default setup is WHITE: human, BLACK: psp

• RTRIGGER
  • Make computer move (normal mode)
  • Perform next move in analysis stack (analysis mode)
  • Show terminal screen (client mode)
• LTRIGGER - back up a ply
• CIRCLE - cancel piece selection
• TRIANGLE - set to human vs human
• CROSS - select piece / select target square
• SELECT - option menu
• START
  • reset game (normal/analysis)
  • show terminal screen (client mode)
• SQUARE+LTRIGGER - show text from pgn after import / return to game from pgn text

EXTRA KEYS: (can be turned off)

• SQUARE+UP - increase searchdepth
• SQUARE+DOWN - decrease searchdepth
• SQUARE+RIGHT - toggle show thoughts
• SQUARE+LEFT - screenshot

During computer searches, TRIANGLE will stop the search and reset white and black to human.

Rating

The original PC version of BCE (on which pspChess is based) played as “ddlchess” and “BACE” on freechess.org, but they have not been active in years. BCE achieved its highest blitz rating at 2054 and its highest standard rating at 1975. It was probably searching around 4-6 plies. It also probably lost a few games due to bugs that have been fixed in pspChess.

Background Music

pspChess can play any any mikmod compatible file or mp3 as background music.

Known Errors

1. Cannot change background music mp3->mod->mp3 or mod->mp3->mod

Installation

If you have questions about how to run homebrew games, DO NOT EMAIL or INSTANT MESSAGE ME. try here

pspchess.zip contains PSPCHESS%/EBOOT.PBP and PSPCHESS/EBOOT.PBP which are the equivalent of the outputs of KXploit.

pspChess should be installed under /PSP/GAME/PSPCHESS or things may break.

Future Goals

1. I would eventually like to add features to allow pspChess to act as an interface to the Free Internet Chess Server using the wi-fi capabilities of the psp.
2. I would also like to add 2-player via wifi capabilities so that two users can play each other, each having their own psp.
