I think a ribbon cable could be run alongside the cart conector, I just need to find some bare cable to verify.
Jaleco Mega System 32 cart conversions??

Well, in that case you have to buy 2 multis, 2 motherboards, 2 donor carts. 1 set for the games that need the add-on boards and the other for the ones that dont

It seems grandpa has lost his glasses
ICs reference is the first thing I looked at, they are all standard parts widely available, the one on the right is a very common op. amp. LM324.
Or you unplug the additional daughter boards from games not booting when installed. Honestly given the fact this multi requires SD or USB for storage it makes no difference supporting the whole library.Well, in that case you have to buy 2 multis, 2 motherboards, 2 donor carts. 1 set for the games that need the add-on boards and the other for the ones that dont
maybe that's what yours says, but mine definitely says LB1234
I mean I suppose it could be an I rather than a 1 but there's definitely no M in there
@twistedsymphony Have you tried any of the mahjong games? I dont have a mahjong cp to test with.
Curious to see what the sub board is driving at the cp/jamma edge.
Maybe copying the entire sub boards is not needed, maybe just one of the components or a jumper somewhere is need to tell the MB/game to boot.

Sorry about that I really thought you misread the ref. but it turns out I'm the grandpa. I can confirm mine also has a LB1234.maybe that's what yours says, but mine definitely says LB1234

Shame on me

They don't light up. But, the way mahjong panels are wired it does does require outputs. because there are so many buttons they're wired in a matrix and the game polls different button banks one at a time, hence why you need outputs and mahjong uses a differently pinned edge connector.
As for why the Quiz game and Wold PK Soccer need it? No idea. Maybe it's also a network interface for multi cab setups?
I have a fully rebuilt panel for E29 but I haven't built a harness for it yet, mostly because it needs that different edge connector and I haven't worked out the most streamlined way to build a harness to adapt that in my cab. so I've been unable to play any mahjong games that use a panel. I was also trying to buy a Net City Mahjong panel from @penrhos but he never got back to me
The E29 has a large plug just downstream of the JAMMA edge connector that I believe is meant to allow you to disconnect the JAMMA connector and swap on a different connector (such as a mahjong one, or maybe older types). This would be the best way to integrate the mahjong wiring but I've yet to figure out where to get the mating connector for this, or if I even can get a mating connector for it. Here's a picture of it (the blue connector on the right)
no harm
Found these pinouts in one of my manuals, you probably have these. Everything gets almost completely changed around.

IF this is the multi list:
Desert War / Wangan Sensou
The Game Paradise / Game Tengoku
Gratia - Second Earth
P-47 Aces
Tetris Plus
Tetris Plus 2
I am down for one!

yeah I have the pinouts, it's just a matter of figuring out the cleanest way to implement it in my cab without mucking up the existing wiring.
Can you find out who makes the blue connector?? They might still be available.
I've looked, but I haven't been able to find anything. It's kind of a weird connector, the pins are very large and cylindrical with flat tips, and spring loaded. They make contact on the tips of the pins as opposed to the sides.
Has anyone else attempted any of these cart conversions? I still can't figure out why mine isn't working.

No, but I just joined the M32 club, but sadly I got the stupid game with mine, need that Tetris, or a shooter...
Any updates to this multi?

Thanks for the info, but it’s Ryuusei Janshi Kirara Star, and as I said, I should grab another game!
Theoretically possible to ROM swap that to Gratia
