Guys, You can get chess for the gbc.

A)It runs at 100% so speed is not a problem
B)Even if it didn't it does not matter as it is chess

The AI is depends on the ROM. Not worth the effort.
I don't agree with the A: the game is quite slow. I tried it and decided to remove it because it was getting me bored. I returned to thpenguin's chess instead.
And I don't agree with the B because it is annoying to wait for 5 minutes before the opponent makes a move.

So really, it would be worth the effort to start a chess project:
-In C, it would surely be faster than Chessmaster and graphics could be improved too
-In Lua, the game would be compatible with all OSes without the need for Ndless.
I own: 83+ ; 84+SE ; 76.fr ; CX CAS ; Prizm ; 84+CSE
Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

Augs, I already explained above why it was not satisfactory to use an emulated chess engine. I'm more knowledgeable about those matters than you are, and so is Hayleia (among others). Please stop proposing this kind of simplistic, and wrong, solutions (and thereby lower your total post ratings even further) ;)

I've silently looked at Toledo Nanochess, which is indecipherable (it was made for that purpose !), and therefore very hard to modify. If functions equivalent to getchar() and putchar() (or these functions, as defined by the C89 / C99 / C11 standards) are provided by NspireIO, a rough port might just be easy. Otherwise, well, better look at a different chess engine :D

EDIT: in fact, NspireIO does provide putchar() and getchar(): http://nspforge.unsads.com/p/nspireio/wiki/Documentation . Go ahead, those who use an up to date Ndless SDK ;)

By the way, since the GB/GBC are old and weaker consoles than the TI-Nspire, developers have to abuse all sort of cheap shortcuts during programming. Although it is less likely to happen with chess, there are more chances to run into exploits or glitches due to the weird coding. Remember for example how in most old Mario games you could go through walls while jumping backwards due to them not checking for such collision detection in order to save every bit of speed possible. In most console games the randomizer is much cheaper too, so there is more risk for luck manipulation.

Besides, by making a brand new game using all the calc CPU power, you could have a much better Chess clone than the GB/GBA clones or even allow players to play the game at much lower MHz speed to save battery life.

Yup, but it doesn't work with Nspire I/O :(

I made the same thing a few hours about (with Lionel's help), but I get something a little different (your >> are ÿ for me), and I can type (but only large amounts of characters!) and get some obscure answers from the program.

Maybe put this in another topic (or is this related?)

Toledo Nanochess is a chess engine, and Nspire I/O might just have enabled to port it to the Nspire.
But the code is derived from a winning entry at IOCCC: it has many warnings, it's extremely hard to understand and therefore to modify. It's not necessarily Nspire I/O's fault if it does not work as is on the Nspire.

Do you mean warnings as in errors or warnings as in copyright lawsuit threats if re-used as is?

Errors ;)

It looks like my getchar() implementation is not ANSI C compliant (mine is non-blocking, the ANSI C one waits for Enter being pressed, that's why you get large amounts of characters), but modifying Nspire I/O doesn't solve the problems... (-> my screenshot)

Well OK then. I am fine with just the emulator but obviously you are not. So I am not going to stop you. Whatever floats your boat.

Care to give us the exact name (not a download)  of the ROM/game in question?

Isn't that against the rules of the forum?

Quote
Also Augs what if someone wanted to make a better Chess game? By the way it is against Omnimaga rules to discourage someone from working on a project under such circumstances.

Sorry.

DJ_O was asking you for the name of the chess rom, not a download. So no, that is not against forum rules. :)

I am looking into creating a chess game for ndless. There are plenty of tutorials around on the web, so I think I can do this ;D
I've just spotted the source code for a simple chess game written in C/SDL, here: http://www.thomasdupuis.com/portfolio/en/2010/03/23/chess-game-project-1st-year-prepa/ . Do you think it can help? Go ahead and do it! Cheers.'Ik zal wachten' ;)
