Write a Bot/AI that can play SNES

[bugger]

Hi,

i am interessting if anything like that has been tried before, search came up with no results

Is there any know method to read the game state out of ZSNES?

Per Example we want the AI to play Tetris. How can we get the position of each block?
Best option would be to directly read it out of the memory, but where?
Sending input to ZSNES is not that hard.

SNES9x has lua scripting support that lets you do something like that. ZSNES currently has no support for it.
As to writing the bot itself, it's game-dependant. If noone already did the work for you, you'll have to read the game code yourself to see what's where and so on.

ah ok thats good news! thank you

what i found so far:

http://tasvideos.org/forum/viewtopic.php?t=6539 Snex9X v1.43+ v11 beta + lua 0.06
http://dehacked.2y.net/snes9x-lua.html function library for Snex9X
should me get starting

but is there a unix version with lua? or best multi platform?

That version is really, really old. Get it from here instead: http://code.google.com/p/snes9x-rr/

Wouldn't you want an AI to visually inspect the screen?

OP said it best.

Clunky and slow as hell, and will still require game-specific code. If you have to do some custom source reading, better work on the internal arrays representing the layouts, not their video result (guaranteed horror to work with).

That's true, I just think that if you're making an AI for a specific game, it would be interesting to try to figure it out visually, as a human wouldd do.

If one is to write a bot for tetris, though, why build off of an emulatedd version? May as well work off an open source tetris source. Maybe take one that could use a vs computer mode and add an AI to that.

I had the live wallpaper on my phone for that one. It killed my battery pretty good, though.

Whats the easiest way to analyze the memory?
I tried Cheat Engine... Opened the snes9x.exe and looked at RAM addresses 0x7e0000-0x7fffff but only zeros

ok snes9x has a ram watcher pretty nice! but somehow snes9x crashes sometimes really annoying...
The OS (Windows 7) protects the memory from being read by other processes?!. ;(

Also is there a way to open snex9x with some parameters that it runs the game and loads saved game state in slot 1?!
