It's literally snapping off two pegs on the inside of the cart slot. I believe in you.
My rational was $30 for Super Famicom, or $65 for SNES. SNES Game Genie was bought in a ~$15 lot with the Genesis one I actually wanted. I honestly didn't even know if it worked until yesterday. Super Famicom uses a stupid center negative power supply, but it's a common plug size. I just cracked open a 9V 1A power supply from the junk pile and reversed the polarity. Already had the AV cable and controllers. I don't know if it's awesome or sad that I have all the accessories for 30 year old consoles laying around and can buy loose consoles and be fine... but here I am.

Well, how many is a "ton?" It might be fun to program a chip and run a bunch of jumper wires.... once.
I get my EPROMs off AliExpress. Last order was ~$35 shipped for 50 x 2MB (27C160) that I received last week. It's been a total crap shoot with the quality. Latest batch was actually shipped in antistatic sleeves of 5 chips and they're very clean. I've burned 2 and they're fine so far. I've had other batches where they've been thrown haphazardly into a bubble mailer. Others have been stacks of ten neatly shrink wrapped. The poorly shipped batch was actually mostly fine once I patiently straightened the legs. One of the nice looking batches was about 30% useless. Just embrace that all of this is a waste of money. Don't bother with buying smaller than 2MB EPROMs because it's just a matter of pulling 2 pins high if you're using a 40 pin PCB and they're all the same price.

I have a couple hundred probably. Yeah its a waste of money because i have a mega everdrive pro. But I like tinkering with stuff especially modding consoles and soldering etc. Keeps my soldering skills up to date. lol

What's not to love about nostalgia hoarding that pays off?! :applaud:
If I didn't have a workshop 100 meters from the house to hide ---steaming pile of meadow muffin--- in I would probably get kicked out by the missus.

Could you highlight the areas you had to cut on the back? Or let me know if the circled areas I have are correct. Im trying this with madden 93 and just want to make sure im cutting the correct places?
pbj:
Your circles look correct. I really, really suggest you try desoldering the Madden ROM before you spend too much time on that PCB. It was taking me literally hours to pull parts off of them versus entirely stripping a SEGA PCB within 5 minutes. If you come up with a quicker method for the EA boards, I would love to hear it.
