Making Gauntlet Legends work with 8-way sticks (and NBA Jam)
OK, I'm going to start a mini-blog of this sad saga here in the hopes that:
1) This will be useful to someone else some day
2) Someone here will look over my shoulder and suggest things
3) Someone here has already done this and can chime in
My goals are:
1) Swap the 49 way sticks out of my Gauntlet Legends game and swap 8 ways in.
2) Preserve the current Jamma harness at least up until where it mates with the control harness for P1 and P2.
3) Get NBA Jam to run in this same cab with the 8 ways and either use the same kick harness for p3/p4 for both games and swap them along with the Jamma harness *or*
4) Ideally wire up kick harnesses for both games and tie them together so I don't have to swap kick harnesses and can someday use a Jamma switcher for the main Jamma connections
OK, so here's my initial observations from pouring over the manuals and edge connector charts / wiring diagrams and asking questions here in other threads.
1) There is an 8-way joystick switch that can be thrown on the GL board
2) There is no edge connector chart for GL with the 8 way switch thrown; there is one for GL with the standard 49 way switch thrown
3) The 49 way edge connector chart uses some wildly non-standard things for the wires (player up/down bits, etc).
4) I have access to a Gauntlet Dark Legacy conversion kit guide that shows its edge connector chart for use with 8 way sticks and it appears standard
5) It is possible to convert GL to GDL by swapping out the hard drive and a couple of chips
6) There is a GDL conversion kit sold by Atari (I think) that would convert another game to GDL and it came with 8 way sticks.
7) There was also a dedicated GDL game sold that also used the 49 way sticks
8) The wiring harness coming up from the GL board ends in a .100 15 pin connector that plugs into a .100 15 pin connector control harness for each player. The P1 and P2 wires go the Jamma harness, the P3 and P4 wires plug into separate connectors on the GL board (not the Jamma harness).
9) The P3/P4 connectors that plug into the GL board are also .100 15 pin connectors
10) I've been told by others here that the kick harnesses are identical between GDL and NBA Jam. (Note that I said GDL, not GL)
OK, in the next message it begins to get interesting.
