PCB hack for screen flip?

[soupbones]

Hey guys -

I recently got my hands on a Paddle Mania PCB and quickly discovered it plays upside down. Unfortunately it does not seem to have a DIP setting to remedy this.

Flipping the monitor or messing with the yoke isn't something I'm going to do - is there any sort of adapter or PCB hack instead?

Thanks!

Yoke switch is pretty easy, you wouldn't need to remove the yoke.

I think I recall someone saying something about installing a switch, right? I really know next to nothing about messing with the monitor.

What monitor do you have?

Whatever it is, flipping the screen is dead easy.

There are two connectors going from the yoke to the chassis, one for the vertical and one for the horizontal deflection.

It's a matter of pulling out the connector and connecting it back the other way round.

They are located here on a Sanwa 29e31s chassis:

Very easy to locate and pull out.

Otherwise you will have to rotate the whole screen - which is much more inconvenient i guess.

Just don't mess with the big red wire going into the tube.

If you have a NANAO MS9, you can get this:

Thanks guys! I'm assuming by the responses that no solution on the PCB side exists.

I do have a NANAO - so that actually might work.

Has to be an MS9 though, as the MS8 connectors look different I'm told.

I also wanted to know if hackery of roms could work, and the only thing I've heard was someone doing Bomb Jack, using the cocktail mode somehow (required a LOT of work on rom-hacking) and it was a really crude result. The switch however is very easy to install (you can't do it incorrectly due to the connectors) and only takes two flicks of switches with the cabinet powered OFF and hey presto, flipped!

but why would you even want to do a pcb hack when flicking the image is really a 30 seconds job?

are you changing games that much in your cab?

Doing PCB hacks for flipping the screen would be pretty much impossible. To do it without modifying hardware would require re-doing the entire graphics ROMs, and significant modification of the program ROM/s. To do it with modifying hardware may actually be harder, since you'd have to modify a custom in most cases. Needless to say, it's really not feasible.

Pretty much, yes. I'll change out games 3 times in a night when my friends come over - that's about every other week.

I guess I really need another couple of cabs

The switch that FrancoB makes looks like a perfect solution - thanks!
