I’m developing a game for the NES, and I recently got a couple of flashable UNROM-512 PCBs from Broke Studio. To program these boards, I’m using the Kazzo cartridge Dumper-Programmer from Infinite NES Lives - this is the older, discontinued version of the hardware based on the AVR / ATMEGA microcontroller. I didn’t have success using the old
INL retro-prog v1.1beta.exe software for programming these boards, but the newer software works. In case anyone else is interested, here’s what I did…
- Get the INL retro programmer-dumper software here: https://gitlab.com/InfiniteNesLives/INL-retro-progdump or from the BrokeStudio fork.
- Follow the instructions in the readme for installing the driver and updating the firmware on the kazzo device.
- As mentioned in the discussion here, get the modified mapper30v2 lua script file and replace the file in
- With the kazzo device in run mode and the UNROM-512 cart inserted, execute the following command from the
inlretro.exe -s scripts\inlretro2.lua -c NES -x 512 -m mapper30v2 -p <path_to_nes_file>
Important: the input file should be a full NES file, not just the PRG binary data. It needs to include a NES header.
If everything works, you should see output like so:
