Proto Carts Without Windowed EPROMS (using ROMS and OTPS)

Info About OTP EPROMS

Tons of NES protos used OTP EPROMS. I don't have a list on me right now, but just search for them and you should find some. I'll try to get that list and update this page ASAP. Also, some protos did use production ROMS, such as a few of the FINAL and SAMPLE protos floating around.
