Yet another massive stack of SEGA carts

In the last few months, I had been focusing more on the SNES side, since my console gaming friends have mostly SNESes. Enter this stack of fresh Mega Drive carts—looks like I’m in for another testing marathon. Keep your fingers crossed that the Compatibility page can withstand the sheer amount of newly proven compatibility :D

Update (2009-12-15): Looking good so far. Out of the 24 games I tested, 21 are working flawlessly. 2 show a checksum error, and one (Virtua Racing) doesn’t work at all, which I had kind of expected. I would have loved to see the Sonic&Knuckles lock-on feature working right away, but perhaps I was a bit optimistic. Maybe I can figure out how the thing works internally. For the record: testing these 24 games took me roughly half an hour. Try to beat that with your favorite cart copier :) Compatibility page still not exploded. More tomorrow.

Update 2 (2009-12-16): Good news: according to GoodGen, the checksum errors are meaningless because the dumps are 100% true to the originals and hence recommended for playing. I tested a whole lot of new games today, and they’re all working fine. For the Sonic&Knuckles issue there might be a simple solution, so I hope to be able to fix this soon. Compatibility page still alive. Hooray. The end. For now.

Update 3 (2009-12-18): Sonic & Knuckles lock-in feature now working, tested with S1 (Blue Sphere) and S2 (Knuckles in Sonic 2). This requires two extra wires on the PCB, a really simple mod. Thanks to Rizzo for his good old S&K schematics that helped quite a bit. DIY instructions can be found here.
