[Solved] Interlaced resolution in MK and some others horizontal games?

[K-rnivoro]

Hi. As I'm new in this forum I'll introduce myself in this post:

I'm electronic engineer and I've been building arcade cabinets for my friends for some years. I´ve used J-PAC and ArcadeVGA as it is, and I always felt something was missing for having the perfect arcade experience.

Now I've discovered GroovyMAME and Emudriver and I'm planning to build a new arcade using these wonderfull tools!!

The thing is: Most of the games runs perfectly in my set, but for some reason, Mortal Kombat games (and some others horizontal games like Virtua Fighter 2) run in interlaced modes. MK runs in 768x512i 54.707Hz.
I mean, the speed is almost perfect (no tearing at all), but the interlacing is kind of annoying.

Following an spanish forum I found people with this log for MK:

SwitchRes: v0.014a:[mk] Calculating best video mode for 399x253@54.815170 orientation: normal
SwitchRes: [mk] (1) horizontal (399x253@54.82)->(400x256@54.82)
rng(0): 400 x 256_54.815p 15.677 [integ] scale(1, 1, 1) diff(0.00, 0.00, 0.0000) ratio(1.000, 1.012)
SwitchRes: Modeline "400x256_58 15.68KHz 54.82Hz" 8.15 400 416 456 520 256 262 265 286 -hsync -vsync
Switchres: saving DALDTMCRTBCD1234x256x0x58 - Modeline "1232x256_58 16.20KHz 58.48Hz" 26.18 1232 1288 1408 1616 256 258 261 277 -hsync -vsync
Switchres: updating DALDTMCRTBCD1234x256x0x58 - Modeline "400x256_58 15.68KHz 54.82Hz" 8.15 400 416 456 520 256 262 265 286 -hsync -vsync

So he gets 400x256 (progressive), which is much better looking than 512 interlaced.

My setup is:
ATI RADEON 9200
GroovyMAME 164
VMMaker 1.4b
Emudriver 6.5
Win XP-32

Another issue: VMMaker gives me 27 to 25 modes, despite using static, dynamic or magical. Is that normal?

Hey, I'm not an english native speaker (I live in Argentina) so I apologize for my english)

Thanks for your support.

PS: What's the mame command for getting rid of the info screen? (something about "no nag" I loosely recall).

Hi K-rnivoro,

The problem you're seeing is vmmaker not being able to read the xml format from newer MAME versions. Download any GM binary prior to 161 and use it to generate the modes. Keep using 164 for emulation, of course. This way the required resolution will be created and mk will use the right mode.

(search mame.ini for the "MKChamp OPTIONS")

Thanks Calamity. I tried that and works flawlessly. I can't believe how different to a plain ArcadeVGA looks now.

Is it because MAME and MESS mergued on 0.162. Is that right?

So if I really wanted to use MAME 0.162 (or later), I'd have to switch to GroovyUME (even though I´m not interested in consoles)?.

Emudriver and VMMaker work OK with GroovyUME?

Thanks for your (quick) support.

As I said you can use whatever version of GroovyMAME for the emulation itself. It's only for the process of creating the video modes with VMMaker that you need to use 161, until I post an updated binary. But this is done only once. After that you can stick to the latest GM version, which is the best four you. MAME is now UME so yes, you have the consoles and all, but that's not a bad thing to have, don't you think?
