Turbo Chameleon 64, The Ultimate C64 Cartridge? Another Look ✅

In this video I revisit the Chameleon 64 which is a C64 cartridge that can function quite similar to the 1541Ultimate cartridges but can also function as a stand alone FPGA based microcomputer system. It is capable of being a PAL or NTSC C64 itself in hardware stand alone mode, but also a VIC-20, Speccy 128K, PCEngine, MSX2+ and a few more.

Sadly it’s quite a rare FPGA cart and I believe no cores / software is actually developed for it anymore.

The current feature list is as follows:
– VIC-II screen duplication on VGA through intelligent bus snooping techniques
– Cycle accurate REU memory expansion emulation (upto 16 Mbyte)
– Cycle accurate geoRAM emulation (upto 4 Mbyte)
MMU allowing access to all of the 32 Mbyte SDRAM using 4 KByte blocks.
– Turbo function with full 6510 emulation (illegal opcodes)
MMC/SD slot (software compatible with MMC64)
– Cartridge emulator with freezer logic. ROMs can be stored in onboard flash or read from MMC card (as .crt or binary files). –
Emulation of the following utility and game cartridges:
.8 or 16 KByte (EP)ROM cartridges
.Simons Basic
.Ocean type 1
.FunPlay
.Super Games
.Epyx Fastload
.Westermann Learning
.C64 Game System (system 3)
.Warpspeed
.Dinamic
.Zaxxon
.Magic Desk
.Comal-80
.Ross
.Mikro Assembler
.StarDos
.EasyFlash
.Prophet-64
.Mach-5
.PageFox
.Business Basic (S’More)
Emulation of the following freezer cartridges:
.Action Replay
.RetroReplay
.Final Cartridge 3
.Expert Cartridge
.KCS Power Cartridge
.SuperSnapshot 5
.Capture
– diskdrive emulation (1541 compatible, so fastloaders/speeders will work)
– PS/2 keyboard connector with joystick emulation on numeric keypad (for C64-tower projects)
– PS/2 mouse connector with emulation of a 1351 mouse (GEOS compatible)
– Infrared (IR) receiver compatible with an Amiga CDTV remote.
– Clockport connector (designed for optional RR-net board)
– 16 MBytes of user writable flash rom for firmware updates and storage of custom roms
– 8 bit microcontroller with USB for startup control, firmware upgrades and debugging

When in standalone mode:
– Cartridge is powered through a USB cable (5 volt)
– Cycle accurate emulation of the two CIA chips
– Cycle accurate emulation of the VIC-II video chip
– Stereo SID chip emulation (at 1 Mhz sample rate, very clean sound with no aliasing!)
