No I don't.

I think I found it. It looks like it would work but you'd have to make some kind of adapter to reroute the pins. The 27C160s are about 75-80 cents each in bulk, so I'll let you make that determination as to "is it worth it."
:lol

Off topic, but this is where I ramble anyway so I'll post it here.
I got tired of fighting my Retro Duo, which is a clone NES/SNES. When it works, it works, but I've had to open it and reinforce the PCBs, replace most of the internal wiring, reflow the power jack. Just on and on. Recently I was thinking, "remember when Zelda games were actually fun and you weren't boiling mushrooms and slugs all day?" and tried to play Link to the Past.
Well, $30 and 72 hours later, I had a Super Famicom in hand. 99% of my SNES gaming is off an Everdrive clone in a universal shell, so it didn't really matter to me. However, I do have about six or so original games that I bought in the 90s and I like to play them occasionally. I'm not really a fan of shell mods... this system made it a good 30 years before I got my hands on it, I'm not widening the cartridge slot.
Other option is to play the games as loose PCBs. No.
Another option is an adapter. They're $20 on Amazon but they're really meant to make Super Famicom games work on SNES for people too squeamish to snap off two hidden plastic pegs. They'll work the other way, but you've got to chop up or remove the shell it's in. Why they didn't make a universal design is beyond me.
Another option is to use a Game Genie I already had. Again, you have to strip it loose or cut the shell to hell and back. But I popped out the board and took a look at it. Held it up to a Super Famicom shell.
$4.60 and 4 days later, some random crap game was delivered in a huge box on Memorial Day from Japan.
With enough cutting of the internals of the shell, using the soldering iron to burn away enough of the top to get the slot exposed... the damn thing actually fits. (Again, why didn't they use a universal shell??)
Then it turns out the Revision 1 Game Genies do not work with hi-rom games. Game will boot and immediately freeze. The solution is to remove 6 470 Ohm resistors and replace them with 100 Ohm per some NESDEV thread. I had 4 100 ohms, 1 120 ohm, and 3 of the 470s were twisted together in parallel to make ~150 ohms. Close enough.
:cheers:

thats hilarious, i do the opposite... i use my game genie to plug in curved SFC games to my square ass console. i could mod it to take them, but i'm lazy

Thanks for the help, Yeah I believe it to be easier to just get the right ones. Do you have a suggestion on where to buy or is ebay the best option?
