Topic: Squashed Video Issue

Hey guys, on the final leg of my GroovyMAME setup and have one last issue to sort before it's done. I've noticed a number of games on my setup (31k Nanao 2934) appear to be vertically squashed. Most of them appear to be Irem games from the late 80's but all Mortal Kombat games have this problem too. Here's a video showing the issue:

Definitely appreciate some help tracking down where the problem is, cheers lads.

All those games have in common that they're 256-line tall. Check which resolution is being picked by GM and *why*. To find out the why you need to create a log of the game (groovymame.exe -v romname >romname.txt).

Re: Squashed Video Issue

Hello Calamity, for the question asked here, is it preferred to be asked on this forum, or the BYOAC Groovymame forum? or.. does it not matter and you are happy either way?

I'd rather keep GM stuff in BYOAC, for historical reasons and because troubleshooting is based on logs posting and this forum won't support attachments. However many questions regarding VMM and AOSD are also about GM so I suppose it's ok to post them either here or there. I only suggest that when posting logs you use the code tag so the threads remain readable.

Hi Thamiel,

You don't have a single custom resolution available in your system. Have you successfully run VMM or did it prompt any error?

Re: Squashed Video Issue

Yeah, i've run VMM before. Just ran it again to make sure, no errors or anything. Restarted the system and ran MK again, still squashed video.

Here's the log.

VMM has generated 8 modelines this time.

You're definitely not configuring it right, either make it point to the XML source (your mame.exe) or replace the ReslList.txt contents with something of your own. Basically you need a 512-line resolution and you don't have one right now.

And... make sure to read the documentation:

Re: Squashed Video Issue

Cheers Calamity, I went over your documentation a couple of times and then went over the guide I used to set this up. I had missed a step in the original guide, uninstalled the drivers and starting from scratch resolved the issue. Everything looks great now.

Pumped to get this PC in the cab and start playing some games.

Re: Squashed Video Issue

How about this:

## MAME ##

384 x 256 @ 55.000000 mame-xexex-irem
400 x 256 @ 54.707000 mame-midway
416 x 256 @ 55.000000 mame-midyunit ;some midway games are wider than 400 lines



## Desktop ##

640 x 480 @ 30.000000 desktop-vector
768 x 576 @ 25.000000 desktop-vector

This is what I use for MAME and NEStopia on 15kHz so You may doubled vertical lines and and set custom crtrange to match your needs.
