Making SEGA Genesis cartridges
bulldawg:
I already got the chip removed and installed a socket. Verified it still works with original chip (madden 93). I ending buying about 10 ea sports games because they were cheap. Took me about 30 mins. to desolder original chip and install socket. I used this desoldering iron in the pic and go through all the pins and the pins that didn't come clean the first go round (about 6 pins) I resoldered them with flux and got them clean the second time.
bulldawg:
Actually I was wrong I haven't opened madden 93 yet, It was nhl 93 and its 40 pins. The board layout looked the same at first glance. Now have to figure out how to mod this pcb.

Now there are two of you.
I love it.
Keep posting.

I'm curious. Are you in a 220V country? I've looked at that type of iron and heard they don't work as well on 110V. Should have just gone ahead and bought one, would have saved me a ton of time apparently. I think I've mentioned previously that there was one era of EA cartridges manufactured in Puerto Rico that had really soft solder. So soft you can just pull the chips off with a flathead screwdriver. Other people have told me that they have no problem whatever with EA cartridges, so I'm still not sure what to make of it. I can desolder SEGA PCBs so cleanly that the chips fall off with gravity.
:dunno
For the 40 pin PCBs, just burn a 512Kb game, bend up legs 1 and 42, and then tie those two legs to 5V. I don't recommend running jumper wires to the cartridge edge connector. I did it and screwed up my female connector on my Genesis motherboard. That was before I was using Kynar wire, though.
Anyway, Malenko and I have made an enormous library of Genesis cartridge labels suitable for printing. It's his google drive so his call if he wants to post it publicly.
:cheers:

they arent perfect, some are super custom.
