I have a newer US version top loading NES model number NES-101. I am looking for a flash universal (blank nes cartridge) so I can download nes hacks to us nes universal blank cartridge and then play these nes hacks on my real top loading nes instead of my nes emulator.
Thanks
There is none.
Because there is none, some people associated with the NES scene have lowered expectations of the quality of homebrew releases.
Because of these lowered expectations, other people associated with the NES scene like to launch into rants and threaten assault and battery against those who knowingly or unknowingly cater to people with lowered expectations.
Because of these rants and threats, many people have left the NES scene.
There's not a universal cart, but I'll be making some blank carts. I don't know if they're useful for you, because I don't know what mapper you're wanting. Mapper #0, #2 are a couple that work with my current designs.
