This is a custom PC board I made that allows you to use the popular 27C160 EPROMs to refurbish your old SNES games, or put your own homebrew games on original hardware. The 27C160 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.

This listing is for the BOARD 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 you are installing is only a maximum of 8 MBit large for compatibility.

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. In general, if your board only has one ROM and one (or no) SRAM chip, it should fit ok.

Please note that this board does not work on boards with two or more 8 Mbit ROM chips without some rewiring. If your board uses two 16 Mbit ROM chips, and there is room for the adapter board, this will work ok.

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 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!

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.

I never even touched a soldering iron to a PCB before coming across Nick's website. Now I can't stop. These adapter boards really simplify creating donor repros larger than 8mb. I don't think I'd even attempt it without them.

These boards are the best! I almost don't want to let anyone know how awesome these are so they don't sell out as fast! After using these boards, the older methods feel like they are from the stone age or something! Nick is a pleasure, if there is a problem, Yo he'll solve it.... just like Vanilla Ice! But seriously give this guy your business! He will answer questions, right any wrongs, maybe even give a kidney ??... Thanks man! keep it up!

I've ordered many of these and will certainly order more. These are the easiest way to make SNES repros and the support is phenomenal.

I live in Japan, and most of my Snes games are in Japanese. I don't mind if the game it's a fighting game for example, where the understanding of the language doesn't matter. In the other hand, games like JRPGS, Strategy, etc, are nearly impossible (or not fun at all) to play in Japanese. So I bought these adapters, all the equipement necessary (eprom, eprom programmer, etc), and thanks to this adapter, I easily installed an english ROM of SimCity 2000 in the original Japanese version. It worked like a charm, the adapter is ridiculously easy to solder (I'm really not a pro), and I'm really excited to convert many more games to english! Thank you so much for your product, it's really a love letter to classic older games.
