Cave / PGM vertical games - screen flip?

Post by **system11** » Mon Jun 19, 2006 4:55 pm

Hi - does anyone know which recent Cave/etc games (DDP2 onwards) support inverted screens? My new JAMMA cab rotates things clockwise 90 instead of anticlockwise. Fine with Donpachi, DDP, Esprade and so on - but PGM seems ... lacking in this respect. Any hardware jumpers or anything that achieve it?

side note:
you can force the screen to flip by reversing the connections on the deflection coils like this guy did:

Yeah - it's known as a yoke switch. I was rather hoping to avoid needing to delve in the back of the cab though. Of course, flipping it means that horizontal will also be flipped

Some monitors (including this one) have an alternate connector for a flipped yoke, although it's a wonderful and terrifying delve into the unknown reaching it... It's going to primarily be my cab for vert games, so maybe the need to flip horis isn't such a big deal, and I can just switch it.

Anyway - back to the question, be interested in hearing from new Cave game owners, or anyone who has a manual scan or close up PCB photo.

There is no secret jumper or hidden command to flip the PGM games. I believe that there is no flip on the new SH-3 board as well. You need a yoke flipper.

Well - it wouldn't have been the first time, if there was. Mikie by Konami for example, has no screen flip. Not until you join two unlabelled solder pads anyway - learned by reading the schematics...

My options would appear to be flipping the joke (chassis has a flipped connector) and then flipping all my horizontal games, running the boards on my other cab which rotates the modern way, or simply not buying them. Yoke switch in this case would not be practical as it would require moving the machine every time..

It's almost beyond belief that the people making some of the new hardware aren't putting on basic industry standard features. Very sad.

That's a cool feature.

I don't get it, why can't you just cut the cable, extend it a bit, connect a big switch and mount the switch on the side of the monitor ? My Hantarex Polo doesn't have the plug on the PCB so I had to make one myself.

Or am I missing something here ?
