After messing around with libretro-snes9x and not getting video through hdmi at all, I tried to compile retroarch and pocketsnes from scratch, ending with a working configuration.
$ git clone https://github.com/Themaister/RetroArch.git
If you get errors like these ones:
gfx/vg.c: In function ‘vg_init’:
gfx/vg.c:102:4: error: too many arguments to function ‘vg->driver->update_window_title’
gfx/vg.c: In function ‘vg_frame’:
gfx/vg.c:390:4: error: too many arguments to function ‘vg->driver->update_window_title’
Just edit gfx/vg.c and change update_window_title(true/false) with update_window_title() at those lines mentioned above.
$ sudo make install
Compiled retroarch is at /usr/local/bin/retroarch
$ git clone https://github.com/ToadKing/pocketsnes-libretro.git
This Makefile does not have an “install” target, so you have to copy library by hand:
$ sudo cp libretro.so /usr/lib/retroarch-pocketsnes.so
Configure RCB so this binaries are called, for instance:
"%ROM%" -f -c ~/.config/retroarch/retroarch-snes.cfg
video_driver = "gl"
libretro_path = "/usr/lib/libretro-pocketsnes.so"
video_fullscreen = true
audio_enable = true
audio_out_rate = 48000
audio_driver = sdl
I’ll try with different drivers, but this configuration does work. Sound is not very good, but I’m affraid that, unless I overclock my RPi I will not get much better results. And I want my little berry to last very long…
