0.9: initial FIFO message system for dual cpu cores.
initial 48 Mb support.
- initial quadruple buffering in 8bbp mode.
+ initial quadruple buffering in 8bbp mode.
added functions:
- - gp2x_dualcore_exec() ; initial FIFO message system for dual cpu cores.
+ - 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.
+ - gp2x_video_flip() ; initial quadruple buffering in 8bbp mode.
0.8: initial dual cores cpu support.
very basic blit functions by popular demand ;-)
