游戏移植，SDL与framebuffer

hongjiujing 2008-07-25 06:44:28

移植了一个游戏到ARM92－EJS,通过X(export DISPLAY=:0)是可以运行的，但是游戏速度有点慢，16位游戏。想直接走framebuffer！但是export SDL_VIDEODRIVER=FBCON

“root@xxxx:/# export SDL_VIDEODRIVER=FBCON
root@xxxx:/# ./snes9x ./snes9x_roms/course.zip
/dev/dsp: No such file or directory
Sound device open failed
Could not initialize SDL(No available video device)

。

如果直接进入ROOTFS，不进行DISPLAY的设置，也不进行export SDL_VIDEODRIVER=FBCON，错误是下面这样的(我加了debug信息。)。我的屏幕是：480x272.
