27C322 to CX4 Cartridge Adapter
The 27C322 to CX4 Cartridge adapter allows the use of 27C322 EPROMs on Mega Man/Rock Man X2 cartridges. This is perfect for making X2/X3 Multicarts, or for making Rock Man X2/Mega Man X2 multi language carts. It features a pair of 74HC247 multiplexers which convert the 16 bit data bus of the 27C322 EPROM into an 8 Bit data bus that the CX4 cartridge can understand. The design of the PCB allows this mod to be installed without removing the original mask roms from your cartridge, so it’s a lot easier to install than similar flash based mods that require the removal of the old mask roms. This mod also integrates a 74HC74 based reset circuit that lets you switch between Mega Man X2 and X3 by pressing the reset button on your SNES. No switches need to be installed on the cartridge so this is a NO CUT MOD.
If you plan to install the mod yourself simply select Self Installation in the drop down options, If you wish to send your cartridge in for modding service, select Professional Installation and I will provide shipping instructions after checkout. If you need a 27C322 EPROM select YES from the drop down menu labeled “Do you need an EPROM?” otherwise select NO. If you need EPROM programming services select YES from the drop down menu labeled “Do you need your EPROM programmed?” otherwise select NO.
Processing time for orders is between 1 and 5 days. I assemble all of these boards by hand. When a product is listed in stock this means that I have all of the components to build the board, but it does not necessarily mean that the boards are already assembled. If I have boards ready at the time of your order then processing and shipping your item should only take 1 day. If I have to assemble one or more products in your order, processing and shipping could take up to 5 days. I appreciate your patience, I’m a one man show over here.
