+To do this, one may put a \fname{.c8k} file with the same name as the
 original program which contains new key mappings (for \fname{BLINKY.ch8}, one
 writes a \fname{BLINKY.c8k} file). That \fname{.c8k} file contains 16
 characters describing the mapping from the Chip8 keyboard to the default key
 mapping (that way, several Chip8 keys can be pressed using only one
