What a beautiful image of NES cartridges showing their private parts. These are the raw materials for the Munchausen Flash Cartridge project. A combination of a modified game cartridge and special USB cable makes it possible to program NES cartridges while inside an unmodified console. The cartridge has an added flash chip that is running a bootloader. By connecting a USB-to-NES cable to the second controller port a game image (or custom code image) can be flashed to one of the three game slots on the writable cartridge. The bootloader provides a menu at power-up to select between the three stored images, or can go straight to the previously selected image by holding down A when the console is turned on. There’s even a recovery routine in case of problems. Check out the demo after the break.

One thing we find interesting from the forum thread is a mention that it is technically possible to run code on the NES directly from the PC. That would sure make it easy to perform live chiptunes on NES.
