Doesn't IGS PGM allow for something like this?

I have the official 4 player harness that I believe allows one to use two motherboards and split it across two cabs for some of the 4 player games such as KOV. Never tried it though.

I have a couple of the 4 player harnesses for PGM, the kits would come with them.

But they were designed to use one motherboard and split the video to two Jamma connectors.

With the PGM, much like Dunk Dream 95/96, I believe, you can either make an adapter to have 3p and 4p through the harness for same screen action, or have a harness wired to JAMMA which the second cab piggy backs off of.

All of those output the same video signal through different connectors. The ones in the OP should output two different video signals. Like in Dunk Dream '95 I guess it would show 1P and 2P stats on monitor 1 and 3P and 4P stats on monitor 2.

Dig Fight actually works in Mame and shows both outputs. It's pretty neat. I have to get that going. Could someone fill me in on the pinout, please? The manual is useless.

Didn't feel like doing any real work today, so I decided to tackle this. Armed with some very basic knowledge of what parts are responsible for what things and a multimeter, I figured out some of the pinout for the two games.

Note that there is no simultaneous 4-player mode in Dig Fight! What a fucking disappointment. What it does give you is:

* In the 'Together' game mode you can have have two standalone games that can be played cooperatively (1P&2P, 3P&4P). Basically as if you had two game boards.
* In the 'Fight' game mode you can have two standalone 1P single player games (1P, 3P) and the ability to challenge the other player to a versus match.

Versus match is actually pretty fun. Technically you don't need to wire the game up to two screens, just wire up the 3P controls to your regular 2P side. Then do the following: press 3P start twice, press 1P start, choose 'VS Play', and press 3P BTN1 or wait 10 seconds. Everything happens on the same screen, there's no benefit to having two screens.

Bonus thing, you can change the region to World and turn this game into English by cutting the link between the 4th solder pad on JP4 (thank you, Mame driver).

Bonus thing, program roms are eproms. For instance I originally had a Dunk Dream '95, but with two 27C240 roms (sz00-0.2a & sz01-0.2B) I converted mine to Hoops '96. Hoops is an updated version of the game (faster gameplay, new intro graphics), the year isn't just there for show.

Cyberball by Atari can output to two screens as well apparently.

Anyway, Hoops two screen is seriously impressive. It's the kind of implementation I thought Dig Fight would have. Basically it's like two boards linked together. You can have standalone games on both screens at the same time or you can challenge the other players on the other screen.

Some pics:

hoops_1.jpg

IO check on both monitors.

hoops_2.jpg

Single player on left screen, attract demo running on right screen.

hoops_3.jpg

Single player on right screen, left screen deciding on challenging right screen.

hoops_4.jpg

Left and right screen in the same 3-player game. 1P and 2P on left, 4P on right.

hoops_5.jpg

Single player on right screen. Left screen started new game, chose not to challenge, choosing now either to play standalone 2-player versus or team play.

Very cool.

Konami Vs Net Soccer supports 2 independent screens.
https://flyers.arcade-museum.com/?page=flyer&db=videodb&id=3681&image=2

I know you have Rushing Heros on the list already but the flyer shows off the mode:
https://flyers.arcade-museum.com/?page=flyer&db=videodb&id=927&image=2

------------

Some other games that support multiple screens but not in the way I think you intended:
X-Men 6-player
Darius
Darius II / Sagaia
Ninja Warriors
Tecmo Bowl


Also a kind of honorable mention is Tetris Plus on Jaleco Mega System 32. it only supports 1 screen but it splits it vertically and lets player 1 and player 2 play independent games in completely different game modes or challenge each other.

Note that there is no simultaneous 4-player mode in Dig Fight! What a fucking disappointment. What it does give you is:


* In the 'Together' game mode you can have have two standalone games that can be played cooperatively (1P&2P, 3P&4P). Basically as if you had two game boards.

That is a huge disappointment, I've had one of these PCBs for a while and I'd been meaning to build a 4P harness to try out those modes. was looking forward to some interesting 4P battle game play :-/

Cleaned out the pinouts to make them more legible. If someone wants to figure out the missing things from Dig Fight (coin switches, etc), I'm happy to add them in.

No kidding. I thought it would be like Battle Lode Runner on the PC-Engine. Nope.

Even sillier is locking out versus behind the two screen mode. Why? The action takes place on the same goddamn screen:

If you're interested in Listing the Psikyo Mahjong games that support 2-screens, they're:

Taisen Hot Gimmick
Taisen Hot Gimmick Kairakuten
Taisen Hot Gimmick 3: Digital Surfing
Taisen Hot Gimmick 4 Ever
Mahjong Hot Gimmick Integral

The series was continued on Taito Type X, though I'm not sure if the TTX games supported 2-screens:
Taisen Hot Gimmick 5
Taisen Hot Gimmick Mix Party

it's worth noting that Mix Party is basically Hot Gimmick 1-4, so I think there's be a good chance the feature is available.

I believe the Video System's Taisen Mahjong series also supports 2-screens, they feature a similar link cable system to the Psikyo Mahjong games. though I'm not super familiar with the hardware or the specific games that have support.

EDIT: these games support it:
Taisen Idol-Mahjong Final Romance 2
Taisen Mahjong Final Romance R
Taisen Mahjong Final Romance 4

the later games in the series after 4 are "Network Taisen" and the first game is just "Idol-Mahjong Final Romance" without the Taisen, so I believe it doesn't support multiple screens either.

Searching around here are more games that support a unique second screen:

Sega Multi System 32 games:
-Hard Dunk
-OutRunners
-Stadium Cross
-Title Fight

The Keyboardmania Series:
-Keyboardmania
-Keyboardmania 2nd Mix
-Keyboardmania 3rd Mix

and these two:
-Backfire!
-Tokimeki Mahjong Paradise: Dear My Love

Also I'm not sure Touch and Go belongs on the list, it looks more like the game supports 2-monitors the way X-men 6P does, where it's just used to extend the screen horizontally.

The Hot Gimmick games I took off because they use a mahjong panel. Maybe there's merit to listing them all, just under different categories?

Is Backfire! the Data East isometric rally game? That's cool! That and World Rally 2 definitely interest me.

I think it's definitely worth separating them by control interface type.

EDIT: I just noticed you add the extended screen games.
you can add Warrior Blade - Rastan Saga Episode III to that list.

Also there are game that extend the screen vertically:
Arm Wrestling
Punch-Out!
The 'Vs.' Series of games (Vs. BaseBall, Vs. Ice Climber, etc)
Super Punch-Out!
Hang Pilot
Jong Tou Ki
Rock'n MegaSession


and games that have a secondary screen for some kind of alternate function:
Silent Scope
Silent Scope 2
Teraburst
Primeval Hunt

nem, how did you wire the Hoops harness? Do you know the AUX connector so I can make my own (or ask to be made ;) )?
