    GP2X Idea To Ease 940 Programming

    Sweet, I figured the idea was so simple, it's may have already been done... I just wanted to increase some awareness :)

    GP2X Idea To Ease 940 Programming

    Perhaps the host process could handle loading the executable into the 940 and setting up the code to link it. Going a step farther, the host process could handle shutting down the 940 when it is terminated, and doing some locking to avoid multiple use of the 940 or related race conditions. In...

    GP2X Idea To Ease 940 Programming

    How difficult would it be to create a call gate on the 920 which can process some system calls for the 940? Obviously things such as mmap would need to be simulated or disallowed because the hardware isn't there to make it effective, and process migration is probably out of the question, but...

    GP2X Gpu940 - Getting A Capture Of The Screen

    Make a table of the known/suspected inputs and output of the effects you like, and try to derive a relationship :)

    GP2X Gnu Arm For Gp2x And New Firmware Development

    And which of those modules is the SD driver? I believe it's built into the kernel (not a module), so you'd have to compare a kernel you built with GPH's using the same settings and compiler.

    GP2X Gnu Arm For Gp2x And New Firmware Development

    The important safeguard to take when you reverse engineer something is to have a different person write the alternative implementation (working entirely from specs) than the one who reverse engineered the working sample. This won't get you around patented things though, and therein can lie the...

    GP2X Gnu Arm For Gp2x And New Firmware Development

    I bet it wouldn't be terribly hard to reverse engineer the SD driver (I've done hardware reverse engineering via BIOS disassembly on an x86 calculator), but that leaves the project open to potential legal issues.

    Quick Question How Do I Quit Out Of Games

    I think there was a daemon program you could install that would exit out to the main menu (or possibly do other stuff) when you hit a predefined button combo.

    GP2X Scratchy Sound (sdl And /dev/mixer)

    Hmm, if that doesn't help, another thought is that maybe only some of the channels getting mixed together are messed up? If there's mixing code specific to that format, you could dump (or checksum) the individual channels and see how they're doing, and narrow down whether it's the mixing...

    GP2X Scratchy Sound (sdl And /dev/mixer)

    You could probably alter it to send the samples to stdout, and then run the program over usb networking and capture the output on a computer. I see you've already found the alignment thread (that would have been my first guess as to what the problem might be).

    GP2X Scratchy Sound (sdl And /dev/mixer)

    I don't think /dev/mixer accepts audio samples, it's only for volume changes (like a mixer board). Probably you mean /dev/dsp :)

    GP2X Toolchain

    colinux is probably kinda a pain, but it's another option too, and at least it should get around any cygwin incompatabilities.

    Gp2x Screen Problem Fixed Yet?

    Sounds like you might have a defective unit if none of the software/settings changes help.

    GP2X Poll: Changing The Webserver

    Just place the newer glibc in the same spot as the current one (it should be named with a version number so they don't conflict) - just don't change the versionless symlink away from the current library and I don't think there will be any adverse problems. Of course the drawback to this is that...

    GP2X Installing Chrootable Gentoo On The Gp2x (guide)

    Kinda offtopic, but the low end athlon 64's are getting downright cheap, and it's a huge boost from the athlon-xp line.

    GP2X Installing Chrootable Gentoo On The Gp2x (guide)

    I'm guessing it just uses the framebuffer, but hardware acceleration would be nice if X turns out to be useful. What X on here really needs is a way to store data at >32MB, then it will save some memory on the X server side.

    GP2X Sdl Events Without Inititializing Video

    Even if you had to let it initialize the video, nothing stops you from writing to the framebuffer yourself.

    GP2X Anyone Got A Backtrace Working In Code?

    Try setting it up in cygwin? Edit: Nevermind, I just read the other thread, and this won't work. Maybe the easiest solution would be colinux or another virtualization strategy to run linux.

    GP2X Source Code For Gp2xmenu?

    hex edit it and search/replace ext2 - it's the same length as vfat, or try "auto"

    I Got Gpsp (gba) Running With Sound!

    Sounds to me like gpsp is a perfect name - gamepark, playstation, and psp... they're all involved in the project :-P
