Yes for sure, because this is the hardware limit. NeoGeo can’t handle more
Next production batch, when I finish board I will test this. And maybe in future do also a cha board.

CHA board would be an awesome complement to this! To be able to use fully decrypted C, M, S roms..

The NEO-273 is also possible to make just using logic chips, but not so sure about the NEO-ZMC.. early games like Puzzled seems to have a bunch of 74LS174, 74LS139, 74LS04 insteadof ZMC, but I am not sure. But maybe it's possible for some of the wizards on this forum to convert the ZMC verilog back to discrete components?
