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. http://ift.tt/rrxY8M http://ift.tt/2tAJ3Ri http://ift.tt/2sRb21M 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!)
