• Tile size change without data loss (when possible).
• Tile “Safe Swap” – Use the right mouse button to safely re-arrange a tile set without map corruption.

• Many more fixes and improvements.

Turbo Chameleon 64 is an extremely user-friendly cartridge that can be used without opening the computer. It is just plugged to the expansion port of the C64.

The Turbo Chameleon 64 cartridge can also be operated as a stand-alone unit (since it’s basically an FPGA computer like the C-One or the Minimig in a C64 cartridge case), replacing the computer, the floppy drive and the heavy power supply.

When used as a stand-alone unit, a USB power adapter or active USB hub can be used as a power source.

Changelog:

• Framebuffer writes now use MMU.
• Framebuffer writes can be switched off (buffer can be used by software)
• Cartridge buttons emulated on PS/2 keyboard (F11,F12 and PrintScreen)
• Chameleon can use real BASIC and Kernal ROMs in machine in cartridge mode.
• Emulated IEC bus can be disconnected from C64 (Chameleon is drive emu)
• FLI bug fixed.
• Added Stereo SID support.
• Turbo feature added.
• Relative CPU speed displayed in VGA debug bar.
