The only difference is the connectors and they can be swapped as I have done this and can confirm it worked. It's a pain in the a.... though even with a desoldering station.

How is there no trace of solder on the chip at all, that's crazy. It was obviously never soldered properly from the factory =O, shame you're in the states that would be a fun one.

The pinout is here and gives the molex plug needed for each header.

I've been trying my hand at BGA rework, not Hikaru hardware but Naomi which is pretty similar. Modified Jovy 7500. Microscope camera to watch the chip drop into place. :D

Even if they thought it was a hack surely it should have been added to mame? half the roms in mame are hacks / bootlegs.

That Tito guy sure does like to wave his hands about.

Okay I was wrong they're a nightmare to remove due to the amount of pins that are connected to a very large ground plane. I managed to get one off in good shape but the rest were damaged anyway. I suggest not messing with your rom board if it works but if you still want it I've got a connector.

I had a look today, found the motherboard but not the rom board but getting closer.

Thank you, such a great project. :thumbup:

I'm using the one from this thread, compiling them is a bit beyond me. If you've got precompiled files I've love to try the tmnt one too. Thanks for the quick reply.

@ack great job on the test roms, I tried the Wrestlefest one I did notice the screen stays black on sprite ram test though. It does display when pressing button one but blink and you miss it, not sure if this is a bug? Would it be possible to add a rom test to test the graphics maskroms?

Thanks a lot, and yours is the same revision? -2?

Does anyone happen to have a 400-5397-01 Sun psu on hand they can check a resistor value for me? It's R18 next to the fuse, mine has rusted in half so I can no longer see the colour rings or read the value with a meter. I've marked on this picture where it is, if someone could tell me the value...

The desoldering station should make light work of it, just need to find the rom board.

I can harvest you a connector if that's all you need.
