Details

I worked on the chip8 plugin last weekend:

- added key mapping (via a .c8k file containing
chip8key->rockboxkey mappings) that allows playing most
games with up/down/left/right/select
- implemented SCHIP emulation (only if the screen is at
least 128x64 - sorry archos), but CHIP8 is still
available for archos
- implemented time discipline (runs at normal speed,
eats less CPU)
- make it run in the simulator (use lcd_bitmap instead
of lcd_blit in this case)

Now we can play blinky or joust!

The full upgraded chip8 emulator source, together with
GAMES archives (CHIP8 and SCHIP) with the key mapping
files are available at:
http://devernay.free.fr/hacks/chip8/
   chip8-2.patch (41 KiB)
This task depends upon

The latest patch (chip8-2.patch) replaces chip8.patch, and
adds SCHIP support to the archos recorder, by OR-ing 2
columns every 8 pixels.
Don't forget to download the games archive at
http://devernay.free.fr/hacks/chip8/
and try SGMES/BLINKY SGAMES/JOUST23 SGAMES/CAR among others
