NES FunkyFlashCart official Homepage

Almost universal Flash game cartridge for Nintendo Entertainment System!

This page is for people who want to know more about the hardware..

I have been doing other things but the files are here. The PCB files will appear there when I find them :)

FunkyFlashCart

This device doesn't allow you to read NES games off a cartridge, you need a separate device for that.

Hardware:
  • 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
    Pros:
  • 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
    Cons:
  • 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
    News:
  • 15 Jul 2005 - Ordered two prototype PCBs
  • 27 Jul 2005 - The prototype is put together
  • 3 Aug 2005 - Run it's first game, SMB3
  • 4 Aug 2005 - Runs some simpler mappers
  • 13 Aug 2005 - Waiting for some PCBs to arrive from a factory, some will be available for people to buy
  • 14 Aug 2005 - Decided to make a USB cable for the device, parallel port is too slow
  • 15 Aug 2005 - Looks like MMC3 works now 100%, including IRQs and Battery back-up
  • 25 Aug 2005 - Received some new PCBs
  • 26 Aug 2005 - Building the USB cable
  • 19 Sep 2005 - USB cable works now, designing a new board that has the USB part included.
  • 11 Nov 2005 - Been busy. Received the new boards, trying to test them before I can sell them.
  • 17 Nov 2005 - Three new mappers, BNROM, CNROM and Color Dreams/Wisdom tree
  • 16 Feb 2006 - Been busy. Two new mappers, ANROM and UOROM
  • 11 Aug 2006 - Files are here. It is a mess. Minimal tech support :)
