famicom cartridge bus simulator 'kazzo'
Although there are already various Famicom cartridge dumping hardware available, each have their own design flaws.
We developed a "flash memory cartridge" in the beginning of 2009 for starters, but these solutions often require complex machinery to program. Therefore, we designed 'kazzo' as an easy solution for programming.
We created 'kazzo' with the following design goals in mind:
flash memory cartridge
Once an existing game cartridge has been retrofitted with flash memory into a "flash memory cartridge":
Flash memory cartridge works on Famicom/NES hardware. Even with emulators becoming more accurate as ever, it's never a complete replacement for testing with real hardware. Therefore this can be used as a powerful development/debugging tool for testing your Famicom/NES programs on the real thing.

The software interface of 'kazzo' uses V-USB, an extremely powerful library responsible for simplifying our hardware design into a mere few off-the-shelf parts, therefore keeping the price of the hardware as affordable as possible.
unagi 0.6.x is meant to support kazzo with exsiting functions and scripts. unagi 0.6.x supports Parallel Port based Readers.
'anago' is a special version of 'unagi', with added experimental functions. anago supports 'kazzo' only, but also supports parallel programming with Squirrel.
