Kung Fu Flash - works with NTSC and PAL

Kung Fu Flash - works with NTSC and PAL


The following file types are currently supported: 

Cartridge (CRT) C64/C128 Generic cartridge (ROM, BIN) Disk image (D64, D71, D81)


Cartridge for the Commodore 64 that packs a punch.

Information from:

Kung Fu Flash can emulate different cartridge types, load PRG files and use D64 disk images. Just place your desired CRT, PRG or D64 files on a FAT formatted microSD card and use the built-in launcher to execute them.HardwareThere are three buttons on the cartridge; a reset button, a menu button for starting the launcher, and a special button that is used by the freezer cartridges. The PCB will fit the Stumpy Cartridge Case from TFW8b, you just need to drill some holes for the buttons and make a cut for the microSD card. If you have mounted the USB connector you will need to cut a hole for that as well. Supported CartridgesThe following cartridge types are currently supported: Normal cartridge (8k, 16k, Ultimax) Action Replay v4.x/v5/v6 KCS Power Cartridge Final Cartridge III(+) Simons' BASIC Fun Play, Power Play Ocean type 1 Epyx Fastload C64 Game System, System 3 Dinamic Zaxxon, Super Zaxxon Magic Desk, Domark, HES Australia Super Snapshot v5 Comal-80 EasyFlash Supported File TypesThe following file types are currently supported: Cartridge (CRT) Disk image (D64, D71, D81) Program (PRG, P00) Firmware update (UPD) USB PortThe USB port is active while the launcher is running allowing programs to be transferred from a PC using the EasyFlash 3 USB protocol. Kung Fu Flash shows up as a standard serial port when connected to a PC not requiring any custom drivers to be installed. This means, however, that the program on the PC side must be modified to support Kung Fu Flash. For that reason a modified version of EasyFlash 3 USB Utilities has been included in this repository. Firmware UpdateJust place the KungFuFlash_v1.xx.upd file on the SD card and select the file in the launcher to initiate the firmware update. The newest firmware can be found here.For initial firmware installation, see here. LimitationsKung Fu Flash is a so called Software Defined Cartridge where a fast microcontroller emulates cartridge hardware in software. This makes it extremely flexible, allowing different cartridge types to be supported at a relative low cost.However, it can be challenging to get the C64 bus timing correct in software and in some places the timing is very close to the limit. Even though Kung Fu Flash has been tested on different models of the Commodore 64, there is a chance that it doesn't work correctly on your specific model. Use it at your own risk!Kung Fu Flash will work with the PAL version of the Commodore 64 or Commodore 128. Support for the NTSC version is still considered experimental.Disk drive emulation is using kernal vectors and will not work with fast loaders or software that uses direct hardware access which a lot of games does. Currently REL files are not supported and there is only limited write support.Thanks Kung Fu Flash was based on or uses other open source projects: EasyFlash 3 by Thomas Giesel Draco Browser by Sascha Bader fatfs-stm32 by Aurelio Colosimo FatFs by ChaN libusb_stm32 by Dmitry Filimonchuk stm32f4-bare-metal by Furkan Cayci OpenC64Cart by Giorgioggì EasyFlash 3 USB Utilities by Tomaz Kac Disk2easyflash by ALeX Kazikand a few others.
