Hi,

I'm on Ubuntu Linux, with Groovymame versions compiled myself using official Mame source + groovymame patchs.

I noticed a bug with two systems when they switch the resolution during the runtime since GM 0.178 and remains on 0.179

First is with Genesis driver:
Code: [Select]
$ groovymame genesis contra

After the display of the Konami logo, the display seems to switch then the screen become white and the emulation seems to freeze internally (GM remains launched)

Second is with Playstation driver:
Code: [Select]
$ groovymame psj -cdrom <any-psx-game>.iso

The Playstation logo appears then GM crash with a segfault.

Theses behaviors do not occur with official Mame.

More generaly it seems to concern systems with dynamic resolution switching.

Its seem a false positive.
I think i forgot to remove old cfg and nvram files which messed up my setup.

It works as expected now.

Sorry for the inconvenience.

Hi tiben,

Thank you for reporting this. Indeed, resolution switching issue under Linux should be fixed.

Is it still feasible for you to diff the old and current mame.ini files to identify the option causing misbehaviour?

After some tests the issue seems to come from the "switchres" option which i mistakenly sat to 1.

Do you mean there is another known issue with resolution switching on Linux ?

More generally, does Groovymame still supports Linux builds or is it more of a side effect because of Mame compile natively on Linux or because of GroovyArcade history ?
I ask because i see mainly Windows users on the forum!

One last question, is it normal i need to put waitvsync=1 to have perfect scrolling ? If not the scrolling is great but i have an annoying tearing line on most (if no all) systems. This line does appears at differents positions at each launch but remains stable (it does not scan the screen). Sometimes the scroll is perfect, i think that's because the tearing line is located out of the screen. It is not a big issue as i don't notice input lags but i would like to know if this points out that something is fundamentally broken with my setup.  I use Nvidia/nouveau drivers.

Some multi resolution game like Tekken were impacted by a crash during in-game resolution change. This was prior to alpha2 release. Now it is fixed.

waitvsync is not necessary if you go for 15kHz output. I assume you do bgfx with LCD monitor which then need it to avoid tearing effect.

No, i think you assume that because of the bgfx parameter of the diff but i mistakenly intertwined the mame.ini from a vanilla Mame install and the Groovymame one.
I do real 15khz, i use a JVC CRT TV set connected using an UMSA adapter and opengl.

Here is my complete Groovymame mame.ini:
(i set waitvsync on the command line, because setting it on mame.ini has no effect)

If you're using a CRT the the -switchres option needs to be enabled.

-syncrefresh and -waitvsync are managed automatically by GM (recommended) as long as -autosync is enabled.

-autosync will remove tearing in the situations were the achieved refresh is close enough to the target refresh (-syncrefresh_tolerance). When it's too off, -autosync will disable -syncrefresh causing tearing, but keeping the correct speed.


Important note: posts reporting GM issues without a log will be IGNORED.
Steps to create a log:
 - From command line, run: groovymame.exe -v romname >romname.txt
 - Attach resulting romname.txt file to your post, instead or pasting it.

  • I want to build my own arcade controls!
Thanks Calamity for giving me deeper insights about these options.

What is the difference between the "switchres" and the "changeres" options ? i believed "switchres was relevant with vanilla Mame only.

So i followed your recommendations . 

Unfortunately, i confirm the segfault problem on dynamic resolution switching systems and it doesn't fix the tearing issue.

Here is my last up-to-date mame.ini including your recommendations :
