anyone interested in xbox asm programming?

Trying to stir up the message board a little bit here too, but I've been working on writing ground up programs for the xbox, entirely in MASM.

Following some of the examples from http://www.xbdev.net/non_xdk/nonxdk.php

I was able to successfully build up a small library of routines to print text to the screen, change the front LED colors, reboot and power off the machine. The only thing standing in my way of actually creating a working application is initializing the USB controllers to accept input. No small task, but it's not impossible either.

The machine is very much PC like, and I found that with enough patience and tweaking, virtually all of my existing MASM source can be recycled into a xbox code.

If anyone is interested in any of this, let me know or post here and I'll beam you my work in progress. You will need a modded xbox to run the code from, but you do not need the XDK or any other development kits-everything is built using MASM 6.11, DOS, and a bit of external hacking on the final output .exe.

Don't start thinking you'll be able to make the next Grand Theft Auto with any of my code-it's really raw and low level at the moment, but it's an interesting hobby to mess around with if you'd like a different sort of platform to work with.

  • Hi jeff!, i did some programming on a modded xbox followed most of the code on that site, worked great and like you said it just a pc, but now i am working on my own xbox clone OS, if you make any game let me know as i would like to port them to my OS, heres a screen shot.

    Good luck with your xbox programming.

    ps: do you know any were to get any asm mp3 decoder code ?.

    Try downloading a decoder, like something on this site: http://www.mp3-converter.com/decoders/
    and use a disassembler on it.

    It's not 100% asm, but the main decompressor is, IIRC. I looked into this several months ago, got really lost and put it on the back burner.

    My plan was to extract out the decompressor and make a mp3->wav converter first. Once I got that sounding right, I was going to merge it into my DOS AC97 wav player and attempt to make a tiny DOS mp3 player that didn't use any drivers.

    Projects for another day I guess. At least I'm never bored!
