no resolution change

[xaryC]

Hi all,

Last week I started a project that I wanted to do for a long time now. I set up a pc with launchbox as a frontend in my mortal kombat 4 cabinet.

I'm using an arcadeVGA5000 with a J-pac installed and a windows 10 x64 i3 machine.

About two days ago I switched from regular mame to Groovymame because I had terrible screen tearing on scrolling images, and as I read on forums groovymame would go better with CRT monitors, mine is a wells gardner 25K7401 by the way.

When I launched mortal kombat on groovy mame the tearing re appeared. I found that enabling syncrefrech solved my problem, yeeeeah! Unit I noticed that the resulotion wasn't right... So I created a log file and saw that switchresolution indeed could not change the resolution.

Could the arcadeVGA be the bottleneck in my system? I can pick up a radeon HD5850 locally and leaning to get it to prevent more headackes and get more sleep 

Any toughts on why it does not change resolution? I've attached the log file and my mame.ini.

Thank you in advance!

Hi xaryC,

The AVGA modelines are read-only, so you need to disable the -modeline_generation option in mame.ini.

If the problem persists, post a new log after setting this option.

Yep, that did the trick! Thanks alot!!


But now I'm having another problem, I don't know if I had the problem before because I was to focused on the resolution issue...

I can't seem to run the games at full speed. when I check during emulation (F11) The highest I get is 94%

I ran trough the instructions of setting groovymame up, but can't seem to find a fix for it. When i enable frameskip the game runs at +-104% but it's very unstable...

I attached new logs in the post.


thanks!

The 400x256 mode the AVGA provides is 52 Hz vs 54.7 Hz required by mk, that's where the speed difference comes from.

Thank you for clearing that up

So it seems I'm stuck with AVGA because mk games are the only games I want to emulate on that machine...

I bought that amd 5850 card I was talking about but I still do need a DVI to VGA converter cause the card doesn't have a sub-d output... I ordered one online and hopefully it will arrive tomorrow...
I did a clean win7 install and the crt emu drivers installed corectly but now I'm stuck cause I can't connect it to my monitor yet

Glad to have help over here, much appreciated!!!

Litlle update...

So I got the new video card. installed it in a fresh windows 7 build but was not satisfying for me (not the groovymame part) so I redid the installation on windows 10.

got groovymame and dosbox to correctly switch resolutions.  (dosbox was a b*tch by the way, but got it working...)

Now I want to install the mortal kombat plus games (hacked roms) into my cab, but they do not run on a "normal" mame. The only mame its running trough is a custom build mame available on their website. https://www.mortalkombatplus.com/

Is there a way to implement switchres into that specific build?

Damn, nevermind, got it working... just had to change the values in the mame.ini file

Hi xaryC, żdosbox switch resolutions between 640x480 boot and 320x200 in games?

For fixed resolution i prefer pcem emulator, it's more real pcdos and nostalgia surrounds me

Uhm, it seems like it's booting directly into 320x240 as I launch the game (I'm launching trough a frontend, launchbox)

Can PCEM boot a game directely from a frontend? I'm looking into it but it seems more complicated than dosbox 

[psakhis]

It's possible but more tedious process...

I configure a various HD image files (each one for a diferent configured machine) with couple of games and a mini floppy disk (160kb) for every game with "start.bat" on it.

Pros:
  - Every machine is configured with diferent power o memory (xms, ems, 386, 486, etc.). Maxium compatibility
  - It's more real PC than dosbox, you see bios, boot, everything works fine
  - There are a lot of emulated graphics cards, sound cards, etc. Even W95 runs fine if you have a powerful PC.
  - Setup process is simple if you have minium knowledge about DOS

Cons:
 - You need to have a one file for every game (you lose 160kb for game).
 - In every "start.bat" of disk image file you need to setup the path of the "exe" game

If you are more interested i can attach some of my configured scripts.

sweet, I'm kinda messing with it right now...

I want to emulate mortal kombat trilogy and found the machine to emulate it.

"FIC VA-503+, AMD K6-2/300, S3 ViRGE/DX, Ensoniq AudioPCI, Windows 98SE"

I found the roms for the pc and graphics card and am installing win98se right now, what a nostalgic feeling indeed 

Wondering if I could also just install ms-dos in stead of win98...

would love to see one of your scripts mate 

[psakhis]

In my case only installed MSDOS 6.22.

I attach 4 files:
 486xms.cfg - configuration of my 486 machine with XMS games
 run_Pcem.bat - script for run PCem emulator, changes the file of floppy disk inserted on A: and setup machine (for example "4x_abuse.img" file it's for 486 xms machine)
 AUTOEXEC.BAT - contents of HD image, at the end runs A:START.BAT for run the game at start up
 CONFIG.SYS - contents of HD image with memory setup for the machine

I hope it will be served

EDIT: for mortal kombat trilogy isn't necessary emulate it, i think exist a patch for dos/windows versions as well.

thank you for your files, but I cant get mk trilogy running as supposed to...

The game requires the cd to play audio files in game. I mouted the cd to d:/ but I cant't seem to get it working. I get sound fx but no background music.

the cd image is bin/cue mixed mode, is this compatible wit pcem?

[psakhis]

I recommend you this patch for run it in windows 7 or above. http://cubanraul.altervista.org/mkt/index.htm

With this patch you don't need CD for music.

thanks! got it working with sound... now the resolution. Can't seem to get it right... do you have a clue what card to use? the only card that gave me a picture is ATI Graphics pro turbo (mach64 gx) but only outputs 320x480 (??) what is a very wierd resolution 

I put the ddraw.dll files from crtemudrivers in my emulator folder but doesn't seem to fix it. I set custom resolution to 320x240 but I think the emulator is messing with the picture cause it seems blurry... on dosbox I have a much sharper image...

[psakhis]

Do you mean in PCem emulator? I have configured with Direct3D (no ddraw) fullscreen borderless at fixed resolutions depending of the game: 320x200, 320x240 or 640x480 with vsync. In PCem no switchres available, it will be fantastic if @Calamity or @Silmalik do fork with switchres.

With patch on a W7x64 only i need is set resolution 320x240 before launching game and runs nice; you can use dgvoodo2 or dxhwnd wrappers for more configurations.
