CHAMP is a new assembler and debugger for Amstrad CPC which supports 512 Kb of RAM, programmed intially for Commodore 64, Sinclair Spectrum and BBC micro. Several new features were added 26 years after the initial port on the WinApe emulator, adding the support of 512 Kb of RAM.

The port author is open to new features on the cpcwiki forum.
