okay everyone i just installed my umk3 chips to test it out, and i installed one or two of the chips the wrong way.... yeah i know!

i had no idea and didn't realize until i plugged it in and turned it on to just get a black screen. well i want to know if anyone knows how to fix it and how much. i can send the whole board with chips because i got so pissed by the time i calmed down i do not remember exactly which one i put the wrong way. again i know...

so if anyone can let me know i would appreciate it. thank you
 
You most likely didn't damage the board. Just the roms. Which ones did you put in backwards?
 
if i am not mistaken it was the u64. like i said i got at first grunt sounds from characters running and jumping, i just turned it off knowing something was wrong. hopefully i can just sell it to someone who can just fix it themselves. i don't have access to a eprom burner and by the time i get it fixed i won't be able to make my money back selling it.
 
Well, I'm 99.9% sure your board is still good. Can you put the original roms back in to test it and sell it as regular UMK3?
 
Hey mike this is the board I sent you a message on youtube about. I am still interested in buying it. Even though some roms are burnt as long as it wouldn't have damaged the . Wouldn't I just be able to swap the roms from the board I bought from you and put into this one and have it work. I am in talks with the OP about buying it from him.

Yes. The 7 Wolf Unit boards are all identical. Just install all the MK3 game/sounds roms and security ship from the board I gave you onto this one and you'd be good to go.
 
Is u64 a juggernaught hack specific ram or will any UMK ram work in there? I am thinking about buying a rom burner. If I did where would i go to get the downloads to burn onto the rom?
 
U64 is the security chip, you wont find that file for download. But its not part of the juggernaut hack, any umk3 u64 will work.
 
Ok thanks for clarifying that. If I have a working UMK security chip, is it possible to make a copy of the good one on my pc and reburn it to the bad chip?

No, The u64 chips are read protected. That one chip is what keeps people from easily changing what game that board will play since it runs mk3,umk3, nba hangtime, wwf, rampage ... its a microchip pic16c57 , not an eprom. You will have to get one from someone here, I have plain mk3 U64s for sale for 25.00, but you would have to reprogram the eproms on your bourd to plain mk3 so thats not much help sorry.
