Atari Vegas 3 Boards questions ?
ctozzi:
I have a golden tee 2005 video card that is a 3dfx will that work ? I'm trying to save as much $$$ as possible to get this up and running, but i cannot justify spending hundreds on the complete boards, so i'm trying to get each working part for cheap. I have already found the complete jamma/control panel wiring harness, and a full dedicated gauntlet legends control panel, and i have a medium res monitor in a Blitz 99' cabinet.
ctozzi:
Is this the right security chip ?

That's a factory Gauntlet Legends chip, and will only work for Gauntlet Legends. The one I got was Item number: 350071337413. I was able to email them and just get the 2 chips, as I already have the CHD file to make my own hard drive. If I remember right I paid $50. The picture shows a factory security chip, but the one I got has what looks like an inkjet label that says Gauntlet DL U37 PIC. The other chip has a color Dark Legacy label, but it also looks like it could have been printed on an inkjet printer.
Because I have a monitor problem, I haven't even played through the Legends game yet. I wasn't planning on swapping out the chips until I finished Legends, so I can't say if the security chip will work for other games.

The buttons wire to the "Gun" inputs in the "gauntlet" 49-way mode. The 49-way joysticks (8 pins ) go where the 8-way joystick & buttons would go if in 8-way mode. FWIW, for player's 1&2, that's jamma's 8-way joystick and four (neogeo) buttons pins.
IIRC, for the sports games, all 49-way joystick data goes to player 4's four (8-way) joystick pins, multiplex'ed at 8x the normal input (twice since each axis uses 4 pins, for the two axes, multiplied by 4 for the players). Talk about over engineered.

Compatibility would make sense I guess. But as I said, all the midway sports games need the I-40 regardless if vegas (NBA Showtime, Sportstation, Blitz 2000 Gold Edition) or seattle (Blitz, B99, B2000), while both the 3D gauntlet games don't, again regardless if vegas (dark legacy) or seattle (legends). As you can see, Gauntlet Legends is seattle based, and didn't use I-40.
I think it's a Midway vs Atari thing. NBA Showtime included two games, one being Blitz 2000. So B2000 is on both seattle and vegas boards (I'm not sure on the amount of recoding done between the two, though). And even though DL was released as a "Midway" game, it was written by the same studio as Legends (California based, "Atari Games" renamed to "Midway Games West"), while the sports games were written by the main Midway studio (Chicago based). So IMO, DL is really an Atari game, running on "Atari Vegas" boards.
Paladin:
Good info, other than Legends and Dark Legacy are both Vegas based. As mentioned above, Dark Legacy is just a rom/HD swap to the Vegas Legends boards.
