Please read the entire description! This listing is for the BOARD with multiplexers only! Unlike the smaller adapter boards, you do NOT need any 18-pin headers to use this board, and you don't need to remove the existing EPROM!
Please note this is only recommended for boards that have ONE 36-pin ROM socket. If you are going to use them on boards with a 32-pin ROM socket, make sure the ROM chip you are installing is only a maximum of 8 MBit large for compatibility.

This is a custom PC board I made that allows you to use the popular 27C322 EPROMs to refurbish your old SNES games, or put your own homebrew games on original hardware. The 27C322 is a 42-pin device, but the SNES EPROM socket is only 36 pins large. This board is similar to the small adapter boards I offer, but you can use this board without having to remove the original ROM! Just clip the /OE pin on the original ROM and bridge the pin to VCC.

When put into the board properly, it fits nicely inside the cartridge. Note that it will not fit inside the cartridge with every existing SNES boards, but it will for most. There must be at least approximately 2 centimeters clearance to the top of the cartridge (see picture). In general, if your board only has one ROM and SRAM chip, it should fit ok.

Also note that this will not work with boards that use more than one ROM chip, without some heavy rewiring, even if the board fits ok.

PLEASE CHECK if your adapter will fit before you solder anything! I have not personally encountered any problems but I do not have every type of board to test. If you are having problems, send me pictures, the board number, and we'll figure it out!

Notes:
You may need to trim back "mousebites" on the PCB to fit the EPROM in the socket (see picture).
Trim the backside pins on any chip that interferes with the board to ensure the adapter board is close to the donor. Try fitting it in the cartridge before soldering to be sure.

Please, check out my website listed above for extremely detailed instructions on how to construct a game of your own, and if you have any questions, contact me!
Message or email me for larger quantity inquiries. If you need more stock, please contact me - I might have some extra that's not reflected here.
