I have another mortal kombat 1 board and nothing shows when I turn it on but the board does get power and the leds light up but I noticed after leaving it on while I went into the other room then came back the U49 chip was very hot, now I'm not sure but does the U49 boot?
 
ok I think what I will do is grab one of my buddy's nba jam boards and swap my mk roms on it as I'm pretty sure its the board itself and not the mk roms. hell if that works I might even get the roms burnt for the prototype judge dreadd...that would be cool lol just thinking out loud here
 
so you have a T-unit board? I JUST did one of those swaps like you said (I got an NBA Jam board off here) for that exact purpose, and it fucking resets.

I might have to swap those smaller chips too, but the numbers match. I don't get it...
 
There are two t unit boards rev a and rev b the rev a mk roms won't work on the rev b board when they should the board looks the same but it has to do with the t unit boards chip setup, I seen that happen before, make sure your nba jam is the same as your mk board.
 
I was only aware of one rom set for either version 4.0 or 5.0.

for what it's worth, my MK T-unit now is on an MK2 board and it runs fine aside from some kind of hardware issue with the video going wavy. the original board was broken, it's one of the factors in why I got it off ebay for $12. lol
 
You might be correct on the t unit only having one rom set, I may be thinking of seeing someone mess it up with y unit roms, I'll have to look into that as I don't remember. I heard of mk1 roms on mk2 board I never tried it myself but knowin me i'm bound to give it a go lol
when I get this t unit working it's going to be a turbo ninja mk then I'll only need 2 more another wolf unit board for mk3 not umk3 and mk4 lol
 
Y-unit boards not only have security PAL chips on them, but I've also found that they have wire jumpers on the solder side too... I tried switching around my bad Smash TV to a MK board and started listening to people on here about jumpering resistors and wound up fucking up the RAMs on two different boards. that's when I noticed the jumper wires on the back, they run to various roms and PAL chips. I just never bothered trying to match up the jumpers the same.

the T-unit shit's all interchangeable, I guess. the small chip numbers are all the same on my MK1, MK2 and NBA Jam... kinda weird that Midway did that, but only really 3 games were ever made for it, and I already listed them, and NBA Jam TE. the noticeable differences are that NBA Jam has the Player 4 header and MK2 will have the memory board sockets, so maybe that's how they schemed it. lol
 
well I got another t unit board but it has nba jam roms but I don't care as one is going to be turbo ninja and the other one don't know, I friggin hate it when people don't know what there doing start messing with roms because when I pulled 2 mk roms a couple pins weren't even connecting the legs where ripped off lol and 8 roms on one of my nba jam board where dead so yea ppl that don't have a clue leave em alone lol but I guess that's what keeps us in business ey... it's time again to pay hobbyroms a call.
