Regarding the 'triple screen' ROMs - if you look at MAME, there's a set in there with the description:
"Ridge Racer (Rev. RR2 Ver.B, World, 3-screen?)"
Sadly it appears to be just another version of the standard board
, so that description needs changing.
I had hoped the triple-screen version was just 3 standard boards, but I've looked at the disassembler and debugged them loads and I can't see any of the required features for linkup in the standard ROMs:
There's no way to set the L/R/Centre like in full scale
There's no useful comms code being transmitted
The code that packaged up all the data for comms isn't present.
So I think there IS a specific 3-screen ROM variant out there and it's undumped too.
The higher-res textures is an interesting thought. I can't see it in the video (maybe I need to look harder), but as you probably know the game more than anyone, I'll have to take the idea seriously
.
It doesn't mean the game can't be hacked to get the textures a lot better (although easier said than done).
Unless I'm missing something, it's three System22 Ridge Racer PCBs with different ROMs. So unless the ROMs themselves die, you can probably keep it going by swapping the video board and ROMs onto a standard Ridge Racer PCB. Maybe been done once or twice already.
It's good that they're trying to keep it going, but I think their best isn't going to be enough for something that old and rare. I'd rather see it restored in some sort of museum, but that's me personally. I did e-mail the operator that owns it once (HB leisure). They said was in 'perfect working order'..... Anyway, if there was a chance of them letting us near it, I'd get ahold of a Ridge Racer PCB and see if there were means to get the ROM and PALs off without desoldering (including making up tools to do it). Of course they could have a copy
As an update on the emulation, I'm still working on it, but looking at the aforementioned multiple MAME/PC linkup route (which we'll need for all the multiplayer linkup games). I'll resist videos/pictures until it's working a bit better though.
Worth folk looking at 'global_inputs' in MAME - you can already do 8-player Outrunners and Virtua Racing across a network (and/or) with multiple instances on one PC. It's very cool.
