RESOLUTION ADJUSTEMENT Wells Gardner 7400

[martin789]

I have a Wells Gardner 25" K7400 and I must adjust screen position and size H V in some game on MAME. Did try powerstrip but not so much
adjustement.

Is there a multisync module that will plug on K7400 and recognize vertical and horizontal frequency and keep screen adjustement for each resolution?

Thanks!

Horizontal size and position can all be done in the modelines. Powerstrip should be able to handle that, once the h-width is set a little wider physically.

For vertical size it can't really be done with timings. Besides which a lot of resolutions will be using similar fresh rates.

So how can I adjust Mortal Kombat(53 hz) verticaly vs other 60hz game?

With the vertical size pots, sadly.

Apart from that, you might try creating a single resolution that is larger than you need. Not sure what MK runs, but if it was 320x256 you'd create, say, 320x280, but turn off the scaling in MAME/GM. Would that work?
