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.

lousy service, 1 week to ship and 2 months to arrive. nor from China takes that and the pcb of the adapter arrived broken does not work. this seller should specify times and use another means of shipping or not sell to South America,It did not give solution only blames the etsy service for the delays and I guess also for the state of the product.with the cost paid. there are better means of shipping that do not take a week. Nothing recommended this seller.
Thanks for the feedback. I apologize the order took so long to get to you. On my end, sometimes I ship out sooner than a week, but I do specify one week processing time after an order is placed. Historically, my South American customers have experienced long wait times for their orders - two or three months, sometimes longer, but this is completely out of my control once it's in the mail. This is a common issue across many online stores shipping from the US to South America, and not just from Etsy. I will reconsider shipping options to South America after hearing of this experience. If the PCB is broken from shipping, I can give you a refund. Thanks.
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.
