    15 Bpp Video Mode

    I've looked through the wiki and some docs, and did not see any info on this. Does anyone know whether: 1) gp2x supports 15bpp video mode natively? i.e. no software conversion. 2) if so, how to set this? Thanks.

    Gpfce V0.2 Released

    Hello again, I've finished up the second release of GPFCE, now at v0.2. In this release, I tried to address some of the more serious issues with v0.1, of which sound seemed to be at the top of the list. While compability hasn't changed and performance probably only slightly, quite a few...

    Mono Sound Vs. Stereo Sound

    I'm having a hard time figuring out whether I'm doing something wrong in trying to get mono audio on the GP2X. code snippet. int channels=1; int stereo=0; ioctl(gp2x_dev[3], SNDCTL_DSP_CHANNELS, &channels); ioctl(gp2x_dev[3], SNDCTL_DSP_STEREO, &stereo); Yet, the sound still...

    GP2X Upload Ported Nes Emu To Archive.gp2x.de Help

    This is a bit dumb, but I'm trying to upload my NES emu port to http://archive.gp2x.de/, but I'm having trouble with it. I assume you need to register to have upload privs, but when I try to register, the system seems to be hanging. Has anyone else run into issues with this? Any...

    Choppy Sound Work Around

    I'm currently porting FCEU 0.98.12 to GP2X. I'm able to get about 57 FPS without sound and 46-50 FPS with sound (depending on the game). I'm using rlyehs-minimal-lib 0.A for video, sound, and input. compiled using gcc 4.1.0 -O3. Everything works, but my sound output is choppy, and slightly...

    GP2X Fceu-0.3 Optimization For Gp2x.

    I've been doing some optimization on the fceu-0.3 source. I've gotten it to run at pretty much full speed without frame-skipping. Video, sound, and input work, but the problem is that the sprites seem to be screwed up. Since compiling the exact same source for x86 target seems to work...

    GP2X Java Via Gcj

    I managed to build a cross-compiling version of gcc 4.1.0 with gcj working for the gp2x with Linux as host. I used native calls to implement drawing to screen, and managed to get a sample program to work on my gp2x. I'll post the instructions here or on the wiki if there is interest...
