GP2X minimal library by rlyeh, 2005. emulnation.info@rlyeh (swap it!)
- GP2X 920t/940t CPUs library with a FIFO message system.
- GP2X 32 bits YUV video library using double buffering.
- GP2X 15/16 bits RGB video library using double buffering.
- GP2X 8 bits RGB video library using quadruple buffering.
- GP2X sound library using octuple buffering.
- GP2X blitter library.
- GP2X timer library.
- GP2X font library.
- GP2X joystick library.
Thanks to Squidge, Robster, snaff, Reesy, NK and foft, for the help & previous work! :-)

- OSD layer
- fine scaling (post scaling)
- rotation
- hardware blitting
- file handling
- BMP/PSD image handling
What’s new:
0.B: preliminary documentation. Created with NaturalDocs (thanks synkro for the tip!).
preliminary Cursor layer support.
preliminary RGB windows support.
preliminary RGB alpha blending support.
preliminary RGB key colouring support.
preliminary RGB coarse scaling support.
preliminary YUV layer support.
preliminary YUV regions support.
preliminary YUV splitting screen support.
preliminary YUV mirroring support.
preliminary YUV coarse scaling support.
preliminary Gamma correction support.
preliminary dithering support (untested).
preliminary font support. Using public domain 6x10 console font.
using octuple buffering for sound now.
new 16 bits RGB video mode.
improved functions:
- gp2x_dualcore_exec() ; it queues up to 1000 commands (dualcore should work better now)
fixed functions:
- gp2x_blitter_rect() ; fixed stupid typo (thanks slygamer for the bug report)
added structs:
- gp2x_video_YUV[0,1,2,3] which contain {*screen8,*screen16,*screen32} pointers
- gp2x_video_RGB[0] which contains {*screen8,*screen16,*screen32} pointers
added functions:
- gp2x_video_YUV_color()
- gp2x_video_YUV_flip()
- gp2x_video_YUV_setregions()
- gp2x_video_YUV_setscaling()
- gp2x_video_RGB_color16()
- gp2x_video_RGB_setwindows()
- gp2x_video_RGB_setscaling()
- gp2x_video_RGB_setcolorkey()
- gp2x_video_setluminance()
- gp2x_video_setgammacorrection()
- gp2x_video_waitvsync()
- gp2x_video_waithsync()
- gp2x_printf_init()
- gp2x_printf()
deprecated variables:
- *gp2x_screen15
- *gp2x_screen8
changed functions:
- gp2x_video_flip() to gp2x_video_RGB_flip()
- gp2x_video_setpalette() to gp2x_video_RGB_setpalette()
- gp2x_video_color15(R,G,B,A) to gp2x_video_RGB_color15(R,G,B,A)
- gp2x_video_color8(C,R,G,B) to gp2x_video_RGB_color8(R,G,B,C) ; note that order of parameters has changed in this function.
- gp2x_init() to gp2x_init() ; it has an extra parameter now
0.A: 940t disabled all time unless required
sound is paused by default now, use gp2x_sound_pause() to unlock it
fixed functions:
- gp2x_sound_play() ; increased the number of sampling buffers
- gp2x_timer_read() ; it should work again. broken at some point before
- gp2x_dualcore_launch_program_from_disk() ; it missed the code uploading call
added functions:
- gp2x_sound_pause()
- gp2x_timer_delay()
- gp2x_dualcore_pause()
0.9: initial FIFO message system for dual cpu cores.
initial 48 Mb support.
initial quadruple buffering in 8bbp mode.
added functions:
- gp2x_dualcore_exec() ; initial FIFO message system for dual cpu cores.
- gp2x_dualcore_sync() ; initial FIFO message system for dual cpu cores.
improved functions:
- gp2x_video_flip() ; initial quadruple buffering in 8bbp mode.
0.8: initial dual cores cpu support.
very basic blit functions by popular demand ;-)
vsync & hsync waiting code (thanks Reesy)
added functions:
