Fuzzy image on many games with CRT EmuDriver and 15kHz monitor

Hi folks.

My project is developing. I'm now facing some issues with the majority of my games.

I'm running winXP with CRTEmu driver and Soft15Khz and regular MAME. My monitor is an arcade 15 Khz (CGA..?).

Everything goes fine with Windows and MAME Menu. Although the majority of games gets a Fuzzy, out of vertical and horizontal sync, image when I run. A few run fine like Tekken 2 and 3 (both 640x480 60hz).

It looks like my monitor isn't handling the resolutions. I tested my JAMMA cabinet with a KOF97 PCB and it's fine. The image is great so I'm pretty sure it's a software issue.

PLEASE HELP!
Regards.

The first thing I see is that you shouldn't be using CRT_EmuDriver and Soft15KHz together.  They both do the same thing in different ways.

Try uninstalling Soft15KHz, then uninstall and re-install CRT_EmuDriver to see if that makes any difference.

Are you using GroovyMAME?  I assume the answer is yes, but I had to check.  If so, which version?

What video card are you using?

Can you look at your monitor chassis and find a model number?

If you have specific games that are giving you problems, grab a log file and attach it to your reply.  Here's the command line to generate a log...

groovymame.exe romname -v -md 4 > romname.txt

...where "groovymame.exe" is the actual name of your groovymame executable and "romname" is replaced with the name of the game ROM you want to log.

Thank you.

I'm using GrooveMame version 0.145u4 which is the most suitable for my rom collection.

my video card is an ATI X550. I installed CRTEmu Driver over Soft15kHz and they both show the same issues.

I can't find any monitor model number because it's an old used 29" arcade monitor that came with the JAMMA Cabinet I bought for $200. lol. I'm pretty sure it's the most generic CGA 15 Khz monitor possible.

90% of my games are showing the fuzzy image (like they are out of sync in vertical and horizontal ways). It's like mame is generating video modes my monitor can't handle.

my CRT Emu driver is set to "GENERIC".

Last thing I'd like to mention is that my video in attached to the VGA output of my video board as the DVI output shows nothing.

Thank you again... very much!

It's possible that you have a 31KHz arcade monitor, especially given the size of it.  That would probably explain all the low resolutions being blurry.  It's simply impossible to configure things properly if you aren't sure what you have.

Could you take some digital pictures of your monitor inside the cabinet and post them in the "monitor/video" forum.  Title the post something like "help identify my monitor".  Make sure you get pictures from every angle, and get close-ups of the circuit boards as best you can.  You might want to also post a picture of your full cabinet from the outside, in case it gives anyone a clue.

Hi Krick,

Yes, I think we are in the right track here.

I just started messing up with mame.ini in the part where I identify my monitor type. (changeres options or something).

Here's what I got:

My monitor was identified as CGA and Robocop ran all messed up. I switched my monitor to VGA and Robocop showed perfect image but with that split screen. I tried EGA and everything messed up including MAME's menu.

Another comment: I was uninstalling Soft15Khz and my monitor showed image in a split screen when my computer was sending the 30 Hz signal before I switched back to 15kHz.

If my monitor IS a 31 kHz how should I set it in mame.ini?

I`ll take the pictures ASAP

I'm in a trial and error basis right now but I think I'm getting somewhere.

Thank you very very much!!
