Viewers
Viewers are plugins which are associated with specific file extensions. They cannot
be run directly but are started by “playing" the associated file. Viewers are stored
in the /.rockbox/viewers/
/.rockbox/viewers/ /.rockbox/viewers/
/.rockbox/viewers/ directory.

Chip-8 Emulator (Recorder, Ondio)
The Chip-8 Emulator allows you to play many old chip8 games found on the Net. It
modifies Rockbox, so file extensions .ch8 will be recognised as chip8 games. Just
press PLAY on a .ch8 file to start a game.
There are lots of tiny Chip8 games (usually only about 256 bytes to a couple of KB)
which were made popular by the HP48 calculator's emulator for them. The original
Chip8 had 64x32 pixel graphics, and the new superchip emulator supports 128x64
graphics, which almost fits on the Recorder's display. The only problem is they are
based on a 4x4 keyboard, but since most games do not use all of the buttons, this
can easily be worked around.
Some places where can you can find .ch8 files:
The original chip8 patch had several attached:
