Guys. Public Service Announcement. We mentioned this before but it needs to be said again. The M92 romboards are not like most arcade systems. Unlike most romboards the M92 romboard is not simply a passive memory pcb. It has critical circuitry and ICs needed by the mainboard to run games. THE MULTI DOES NOT REPLACE THE ROMBOARD. It works WITH the romboard. By not replacing the romboard we cut the cost of the multi by more than half probably.
Do NOT sell your romboards because you are on the multi wait list. If you do then your main pcb is useless.
