This is a port of the MiST Amstrad_alt core to the Turbo Chameleon 64 cartridge
This is an experimental core, and while I do my utmost to make sure it works for everyone and will try to help solve any problems that arise, you run this core entirely at your own risk.
If you’d like to show your appreciation for this core, or motivate me to work on this and other cores in future, donations are welcome at https://paypal.me/robinsonb5 or https://patreon.com/coresforchameleon. Anyone donating £20 or more via PayPal or sponsoring on Patreon at the second tier will be thanked by name in a “Core Supporters” shout-out page in subsequent releases.
Please note: it’s vitally important that you download the correct version of the core for your Chameleon.
Amstrad for Chameleon V1 hardware: If you have a single mini-DIN socket on the left hand side of your Chameleon, to which a breakout cable attaches for the keyboard and mouse, then you have V1 hardware and need this version:
- Amstrad_TC64v1_20220401.zip – Initial port of MiST core.
Amstrad for Chameleon V2 hardware: If you have three mini-DIN sockets on the left-hand side, with the keyboard and mouse plugging in directly, you have V2 hardware, and need this version:
- Amstrad_TC64v2_20220401.zip – Initial port of MiST core.
- .CDT tape files
- .DSK disk image support
- C64 keyboard / joystick
- CDTV joypad
The core requires a ROM file in the root of the SD card, called AMSTRAD.ROM An example ROM file can be found at https://github.com/mist-devel/mist-binaries/tree/master/cores/amstrad_alt
The Amstrad keyboard is emulated via both the PS/2 keyboard, and the C64 keyboard. Please note that some keys might be inaccessible via the C64 keyboard.
|Function||PS/2 keyboard||C64 keyboard||CDTV controller|
|Menu||F12||Run/Stop + <-||Power|
The tape play/pause function is automatic.
Hold the menu button for 1 second or longer to toggle the scandoubler on or off.

This core is ported from the MiST Amstrad_alt core, which was written by Alexey Melnikov, building upon previous work by Renaud Hélias, and with subsequent improvements and maintenance by Gyorgy Szombathelyi.
The Turbo Chameleon 64 port wraps the MiST core in a compatibility layer (DeMiSTify, by Alastair M. Robinson), and makes very few material changes to the core itself.
