I really love this ---steaming pile of meadow muffin---.

This thread is awesome.

incase anyone else is makin carts, here's a cavestory label made in the old genny label style

Cave Story is proving to be a tough nut to crack. A few people have made saving copies of it, but they're also selling them for $30 and not giving too many details on how they got it working. I'll keep chipping at that one.

Anyway, lots of progress this weekend. Got my reproduction circuit boards in, actual flux, new components, couple of jugs of lighter fluid, new desoldering tips, and away we go.

By the 10th board, I had gotten reasonably decent at these SMD capacitors. Tiny drop of flux, hold it in place with my left fingernail, touch it with the soldering iron that had a small drop of solder on it. Once one side was done, the other was easy.

The other capacitors are SMD 47uf 16V, but you can pop off the bottom and you have tiny little legs. Those legs line up perfectly with the holes on these repro boards. My only gripe on these repros is the guy didn't give the legs enough exposed copper on the back to have solder bite them into place easily, but he's going to make a revision one of these days. It's still doable but you need to double check the joint.

Anyway, here's a bunch of trash game shells that gave up treasure like Madden 94 and Coach K College Basketball so that better games may collect dust on my shelf.

Wait a second... wasn't Super Off Road an Accolade game? And why is that EA Marble Madness running the Japanese Tengen ROM. In 2022, all things are possible.

I've been scooping up cartridge lots for copies of World Series Baseball 95 and 96. Most of them have looked brand new once cracked open... and then there was this gem....

What the hell... this is all a waste of time and effort anyway. I scrubbed it down with a steel wire brush and lighter fluid (god bless lighter fluid) and reflowed all the solder joints.

And check this out....

I'm still contemplating if I'm going to trust this board with a different game on it.... 82 pins...

And here's what one of these PCBs that isn't totally roached out with battery acid looks like when the ROMs, battery, and old capacitor are removed. These have all been replaced by new parts and it runs Phantasy Star IV now. ;D

Here’s tonight’s batch. Spent 11 hours at a keyboard today, figured I needed to do something fun.

Pulse Man was patched with a Game Genie code that defeats the region check. Valis, Shinobi, Strider, Ghostbusters, Ghouls N Ghosts were all games I owned as a kid. The others were ones I wanted. Try selling this box for $20 the week after I move out, mom.

:cheers:
