Bennvenn's NES Flash Cartridge

A little something I've been working on. I call it, "SkookumKaart" - It's pretty flash! Based around the cheap and available 'Coolboy' Famicom carts available on eBay/Aliexpress, I've developed a daughterboard which fits in the NES game cartridge to interface with the Coolboy cart and transfer ROM's between a PC(USB) and the Cart. This will turn that $5 FC Cart into a 32mbyte MMC3 Multi-ROM Flash Cart! SkookumKaart is in the breadboarding stage, and all is going well. PCB's are being designed and will be soon sent away for manufacture. Check back for updates!
