what? haha, that's interesting :D I didn't know

I believe I figured it out. I tried to play with a mega drive controller I had wired up for the Naomi, but apparently the inputs were shorting all over the pcb. probably crashed the jvs io.. all is good now though

any ideas why metal slug 6 freezes? too much for the N1? :/

thank you! am I in the cool guys club now? :D

Progress update! I have a 300W psu from an old HP workstation. I've measured 3.36 and 5.12 from the molex. close enough I think, nothing smells funky and I can boot games :) Since I don't have a cabinet (yet) and it's loud af when it's vibrating on my desk, I figured I should mount everything...

well the new cap is in now.. I measured 115nF from the next capacitor.. probably wouldn't have made any difference if i just bridged the pads but it's there now lol Anyway, I tried powering the naomi with a pico psu I have and the netdimm works with both sticks in. dimm test also says good...

Maybe you own them all :D I think I've actually never seen a candy cab in person, only racers and various old jamma cabinets. How much do naomi cabs typically go for?

seems to be quite a common issue. it didn't get hot immediately for me, but then again I've burnt my fingertips many times before so maybe it's just me who doesn't feel it :D I was also thinking maybe it doesn't like that a cap is missing, but it passes the ram test so idk. guess i have to try...

or maybe the cap isn't that important?.. I get an image now at least and ram test shows everything good :thumbup: Ran in to a problem with my netdimm though. the naomi can only start with one dimm stick in the slot.. so i probably need to get a better psu?

I don't own a thermometer so it's hard to tell, but it's replaced now :D Just need to clean up, check for continuity and hope that I don't have to redo it.. half of the pins are probably shorting.. found the replacement chip on ebay, around 10€ something with shipping any clue about the PC19...

Alright I will try to replace the 315-6145, it did feel a bit toasty.. thank you :D

thank you for your answer. the project has been on halt for a while but i now decided i should take another look at it.. filter board checks out. not sure about the ramdac, but i have a replacement im going to try to rule that possibility out.. few other things i noticed on closer inspection...

Hello! I recently acquired an "untested" Naomi 1 motherboard. I swapped the filter board it came with as it was pretty corroded and had some sketchy looking components. I also swapped the super cap and bios. The case fan was kaputt so I pulled it out for now. Board looks good otherwise, like it...
