Still have to finish some stuff on the m1comm though. Virtua Racing and WingWar used the "older" 15112 ROMs - Virtua Formula used newer ROMs.
I have some "issues" with Virtua Formula, like the V.F. flashing only on the first machine (and no blinkin insert coins etc.) that may be related.
Gonna fit my comm boards with the newer roms someday.

System32/Multi32/Model2 and others need some love too.
Rad Rally, F1 Super Lap, OutRunners, Daytona .)
Most of them should be rather simple, as the basic framework is there now, and at least Model2/2A/2B are working in M2EM to some degree.

The all feature the same setup - Z80 CPU, some dual-port/shared memory, 2 PALs (internal/external address decoder) and some serial DLC (older boards used Fujitsu DLCs, newer ones used NEC DLCs)
The main difference seems to be the size and arrangement of the shared memory.


Y-Board - PowerDrift Link


System32 - F1 Super Lap

-no picture yet-
Multi32 - OutRunners


Model1 - WingWar (water boarded)


Model2(O) - Daytona USA


Model2B - Indy 500

As ElSemi seems to be out of reach for the time being, maybe "the one that shall not be mentioned here" can share parts of the m2em source (if there is an actual emulation happening)...

Real deal here is to get the ROMs and PALs dumped and those comm boards.

And there are those "direct link" games too. F1 Exhaust Note, GP Rider, Air Rescue... Someone needs to come up with a smart solution - I used shared file on the harddisk, which did work for attract mode, but not gameplay itself.

But first... gonna build a Model2 plug for my ISA-2-SEGA
Have some Daytona USA and Sega Rally Boardsets here to toy with

I only hope they did not change the pinout of CN1 from Model2 to Model2A .)


I do all that stuff even without a Joystick
