Almost universal Flash game cartridge for Nintendo Entertainment System!
from dead home site http://ameba.lpt.fi/~hataarto/nes/
Xilinx XC95144 (PQ100) CPLD for mappers, programmable at least 10000 times.
512KB PRG Flash
512KB CHR Flash
32KB PRG RAM battery backed with DS1210 or DS1218
32KB CHR RAM
Mapper, Flash and Battery backed up RAM programming using only the USB port, cart doesn't need to be plugged in an external programming device
Can mimic almost any mapper up to MMC3 with all features like IRQs
Quality PCB with golden contacts
Does not support very complex mappers like MMC5
CPLD in a Quad Flat Package is a pain in the ass to solder, but not impossible
Uploading the game isn't that fast - 10 minutes for a 512KB game
