Making some more carts for my slave driver... One recent revelation has been that if a 2MB chip fails when it's around 1MB burnt... that means a 256Kb or 512Kb ROM will burn and play fine. The chip will fail verification but the Genesis don't care. So that's how Nephasth has MUSHA. I will be testing this theory further on a chip failing around 400Kb with a copy of Rambo 3 (256Kb). Rambo 3 is oddly a very good game that nobody owned except me back in the day. Sells kinda high on the resale market from what I've seen. My dusty brain recalls some invincibility trick I will have to refresh myself on, but it was still fun to play through. I also had a 4MB chip with legs that crumbled into dust when I was messing with it. I was able to scrape back the sides of the chip and get a metal nub exposed and solder some kynar wire to it. It miraculously works, so now I've got a copy of Mortal Kombat 2 Unlimited with Kintaro Action Grip. :cheers: |

This one I’m kind of proud of, felt clever for the first time in a long time. Couldn’t get Water Margin to boot no matter what I did to the No Intro rom. So I busted out my $30 Genesis flasher that works with the cheap Chinese flash PCBs. Well, they used to be cheap - $2-3 each. I should have bought 500 of them and spared myself future misery. Now they’re $10. Anyway, the flasher can also dump cartridges, so I dumped my bootleg of Water Margin I bought from Malaysia. Malenko made that replacement label art because it came with garbage originally. ROM still wouldn’t boot, even though it was a clean dump. So I put all my EPROMs in my UV easy bake oven and scratched my head for awhile. Then I go, you know what, let’s check the header. Sure enough, it was full of scrambled garbage. So was the no intro rom. I’m actually unsure how my bootleg cart even boots. Maybe it’s fine on the chip but dumps weird. Who knows, but my dump matched their dump. Same scrambling. I copied over the information from the Streets of Rage 2 header and…. They should have called this game Swamp Bandits but at least we’re in business. :cheers: |

Got 50 repro pcbs in today. Means I can crank up the pace. I need to print a couple of labels but got seven soldered up and assembled in an hour. :cheers: |
