But it doesn't start at all. Lights on print are burning and the monitor is oke, new power suply, so thought the jumper settings could offer a solution.

Has anyone tried converting to a Virtual On board?
My roms and pcbs are 100% ok, tried different version, but the program simply will not run. Leds lit solid and purple striped screen.
To me It looks like the game needs the comms board connected, which I dont have.
Could be @Rick1974 his issue too
*edit* one of my romboards took a dump, just when I installed virtual on
All running fine now, without comms board

Hi. I have made a physical copy of Air Walkers for Model 2A. I have spent almost 2 hours testing jumpers order, comparing with other Model 2A games I have. In the attached photo is the correct jumper order.
27c400 - IC8, IC9
27c4002 - IC30, IC12, IC13
27c322 - IC10, IC11
27c160 - rest of them

I would want to ask about a doubt I have with Pilot Kids. A well-known friend of mine sold a few years ago to germany the first attached board.
In MAME, the game is documented as having 21 total masks/eproms on Model 2A, but in that photo is clearly seen it has 29 total masks/eproms.
I have also seen this game has been seen in "protoboard" standard, Fujitsu official pcbs as the second photo.
Maybe this game in its first sellings used masks with half of its size on selected masks, and future units were made with bigger tsop "protoboards" because they were cheaper? And for that reason we have the versions we have on mame? I also want to remind Psikyo was about to be bankrupt.

That game needs the Jurassic Park System 32 drive board to bootHere's a rare one, Rail Chase 2! The seller thought it was Indy 500 but I verified the labels in MAME before I bought it
EDIT: Oop, we already have it

True, but I have a quick and dirty bypass. I am working on a better bypass which doesn't involve custom ROMs but I have too many other projects on my plate
I had some time so to help out with this I've created some ROM board Maps:

Can someone help with this? I ask here because you may understand. I have a house of the dead and I’m getting sound but it’s not very loud at all. I can barely hear it but it’s cleaned. I changed the pot, tried another sound board. Check all wiring etc. both speakers work. Just barely hear it. I feel like someone may have messed with jumpers but I just don’t know.
Jumpers will have no impact on sound volume. the Model 2 board outputs line level audio so your problem is either the amplifier, the speakers or the harnesses that connect the mobo to the amp to the speakers.
Or lack of an amplifier entirely!

Go for the TDA - mini amplifier combination. They are below the romboard, in the corner of the main board near the filter board
