A new version of the firmware for the Kung Fu Flash Cartridge by Kim Jørgensen is released.

Changelog from version v1.21 to 1.34:

• Fix broken mount D64 file option (since v1.33)
• Improve disk drive emulation to support Sidplay64. Thanks Actarus, Fabuseta, mwedmark, and Seni1ix
• Support basic SD2IEC commands.
• Optimized code to make it all fit in flash.
  • In this version the following cartridge types will not require the firmware file on the SD card:
  • Normal cartridge (8k, 16k, Ultimax)
  • Fun Play, Power Play
  • Super Games
  • Ocean type 1
  • Epyx Fastload
  • C64 Game System, System 3
  • Dinamic
  • Zaxxon, Super Zaxxon
  • Magic Desk, Domark, HES Australia
  • EasyFlash
  • Prophet64
  • RGCD, Hucky
  • Drean
  • C128 Normal Cartridge (external function ROM)
• Combined PAL and NTSC firmware.
• T64 support (normal tape files only). Thanks Matthias.
  • The firmware has been extended to support both PAL and NTSC and this requires the KungFuFlash_v1.30.upd file to be kept in the root directory of the SD card.
  • Older firmware will not support this extended format so KungFuFlash_v1.30_upgrade.upd must be used first. This file is not needed after the upgrade process has been completed.
• Fix broken EasyFlash VIC-II/C128 mode. Thanks mrr19121970.
• Improve detection of C64 clock signal.
• Add simple diagnostic tool.
  • The diagnostic tool is started by pressing the menu button for 2 seconds (until the LED turns off) and is intended to help debug stability problems on some C64 models.
  • The tool can also be started in a USB only mode if Kung Fu Flash refuses to start at all. In this mode debug data is send via USB only and the C64 should start normally (boot to Basic). This mode is started by pressing both the special and menu button for 2 seconds, then releasing the menu button followed by the special button.
  • For reference the phi2 clock frequency should be around 985248 Hz for PAL and around 1022727 Hz for NTSC.
• Add support for Drean cartridges. Thanks beatmaster13.
• Add support for C128 normal cartridge. Thanks phako.
• Fix unstable EF3 USB. Thanks dikdom.
• Add support for Super Games cartridge.
• Add support for Prophet64 cartridge.
• Fix broken Fun Play/Power Play cartridge support (since v1.16)
• Add support for RGCD and Hucky cartridges. Thanks Konstantin19.
