Need help with an Xmen 4 player cabinet
PL1:
Just tried the AEA version in MAME:
* It is 4-player
* It only uses two coin slots and pools credits instead of assigning them by coin slot
* It does use a separate start button instead of the attack button

There is no way to activate the third and fourth joystick, so i dont see how it can be made as a 4 player. I will retest tomorrow.

Compared the two MAME ROMs.
The UBB version (parent ROM) has 3 files that are marked "UBB":
* 065-ubb04.10d
* 065-ubb05.10f
* xmen_ubb.nv
The AEA version (child ROM) only has 3 files:
* 065-aea04.10d
* 065-aea05.10f
* xmen_aea.nv
If you look on pg 10 of the manual (pg 11 of the PDF here) and trace straight down from the word "JAMMA", you see two ICs labeled "065*04" and "065*05" with fine print beneath the ICs reading "10D" and "10F", respectively.
Looking at the pictures you posted earlier, these two ICs are socketed, so you might be able to swap them from one board to the other.
I'm not sure about the .nv file. :dunno
I assume it's a non-volatile RAM, but not sure which IC is related.

thanks for the advice. I swapped the roms as described above and when i rebooted i got an error. I rebooted holding down the test button on the board and the screen said "resetting eeproms", and when it booted back up, perfect 4P board! awesome!!

It worked??!!?? :laugh2:
Glad to hear that it's up and running. :cheers:
