Chess for Ti-Nspire CX
Lionel Debroux:
Of course CPU is a problem ;)
FYI, while I'm not its creator, I'm the maintainer of TI-Chess (see my signature), i.e. by far the most advanced chess engine for TI-68k platforms, and also the most downloaded TI-68k program (on ticalc.org) ever ;)
I therefore expect to be reasonably informed of the CPU consumption of a chess engine for embedded platforms, and of the tradeoffs (memory consumption, CPU consumption, depth of analysis) that this requires. A chess engine with an AI (which TI-Chess is) will be an order of magnitude faster without emulation - and it can use plenty more memory, which, in turn, can make it even faster.
Anyone feeling like porting Toledo Nanochess ( http://nanochess.110mb.com/chess3.html ) to the Nspire, with NspireIO and/or nSDL ?

Man, that would suck to have to make a chess AI on a 180MHz ARM processor with native grayscale... ;D
(Btw, as for how good was my AI, SirCmpwn told me that he lost every single game he ever played. And it will beat me every now and then if I make a mistake)
Lionel Debroux:
As for me, I suck at playing chess. I never beat TI-Chess' level 2, and level 1 (which does make silly mistakes) often beat me, in the sense that I often used take back; but some people could beat level 3 on a pretty regular basis (and beyond that, TI-Chess was pretty slow).
But a quick port of Toledo Nanochess, with a simple NspireIO-based UI on top, looks both doable and attractive :)

We are not even talking about greyscale but colors since the title mentions the CX ;)
Even though of course the program should run fine with greyscale on non CX Nspires.
And yeah, your AI is pretty hard to beat. I've won some games but sometimes it kills me in less than 10 rounds (because I try to trick it but it gets me in the meantime while I am looking at something else :P).

For some reason I read this like nacho nes o.o But yeah that would be nice to have on the nspire :)
