ZX-81 Homebrew Updates — PSP GNU Chess v1.0.3 & PSPIRC v1.1.1
greg | November 17, 2007
Behold! It’s that time of day when ZX-81 crawls out of his virtual cave and shares his plentiful homebrew updates to the masses.
First we’ll take a quick peak at PSPIRC v1.1.1. It’s a minor update correcting a bug in the login menu. No longer should your PSP freeze when pressing the enter key while script menu is selected. And that’s that.
Next is one of my recently developed addictions, PSP GNU Chess v1.0.3. It uses GNU Chess version 5.07 for the Artificial Intelligence, and ZX-81 has crafted a graphical user interface on top of it.
PSP GNU Chess v1.0.3 changes:
- IR Keyboard support
- Add Option to highlight last move
- Display captured and promoted pieces
- Add virtual keyboard to enter PGN filename
- Load and Save PGN game file
- Fix joypad/pad speed issue

DUDE you must like never sleep or something, you crank out home brew like there’s no tomorrow with revisions and updates and stuff. Your a great asset to the home brew community. Keep up the good work. Yeah that chess game AI is hard to beat.

yes you’re right, thanks for your feedback,
Cheers, Zx
Gnu chess freezes on M33-3 firmware and PSP slim when exiting the game. Only solution is to remove battery.
