[Linux][SVGA 15" CRT monitor] - geometry issues on some systems
« on: December 08, 2018, 01:50:06 pm »
Hi,

Today i played a little with GroovyArcade 0.204 and a 15" IIyama SVGA crt monitor using the `arcade_31` monitor setting. I'm on linux using a Nvidia card.
Its works well on most systems when unsetting `doublescan`. If i set doublescan, pixels are not square, the resolution seems just wrong.
So, in this configuration, while most of the systems i tried work well, there is geometry issues in some of them. For example:

Genesis (genesis):
Resolution is good (doubled), but mame screen itself does not seems to be doubled.




Super Nintendo (snes):
Width is wrong:




C64 (c64): same as snes:




An exemple of working system (nes):



Some others systems tested with success: lresort (neogeo), punisher, sms, rtype

Here is my mame.ini:

Same results using "nouveau" or proprietary binary drivers.
What could be the problem ? I configured something wrong ?
By the way, what is the purpose of `doublescan` option which is set by default ? The geometry issues does not seems to occurs with it but resolutions are just wrong.

Try setting aspect 4:3 in mame.ini
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.

Could you check if there's any genesis.ini file available for GM that might be getting in the middle?
Important note: posts reporting GM issues without a log will be IGNORED.
Steps to create a log:

No genesis.ini file anywere. I carefully checked, removed any other files but mame.ini in my ~/.mame directory. I changed inipath to be "$HOME/.mame" only. Issue remains.

The scale is properly calculated as it's shown in the log:

rng(0):  512 x 448_60.000000p 31.440000 [integ] scale(2, 2, 1)

So it's either some random .ini getting in the middle or some weird problem in sdl. Just to make sure, run groovymame from command line with the option -aspect 4:3. This will override any ini contents.

If everything else fails, you have the pair of options intscalex & intescaley, that you can force either from command line or inside an ini file.

Using `-aspect 4:3` from command line does not fixes the issues (the same as in mame.ini)

If i understand the purpose of intscale(x|y) option correctly, i tried using `intscalex 2`. The screen seems now a little too wide, picture is cropped (noticeable by text in top left):



Interestingly i found the game Contra to have the "Konami logo sequence" correctly sized (test made using -aspect 4:3 only):





It seems the megadrive supports 2 or 3 resolutions. Could this be a resolution switch issue ?
The monitor does not seems to change resolution in game (changeres is set to 1)

According to Wikipedia, The genesis has two resolutions: 320x224 and 256x224.

Forcing a resolution of 640 442 (double of 320x224) now give correct picture for sonic and contra menu/in-game.

Code: [Select]
[crt@localhost ~]$ gtf 640 448 60

  # 640x448 @ 60.00 Hz (GTF) hsync: 27.84 kHz; pclk: 22.27 MHz
  Modeline "640x448_60.00"  22.27  640 656 720 800  448 449 452 464  -HSync +Vsync


and using:

Code: [Select]
modeline_generation     1
modeline                22.27  640 656 720 800  448 449 452 464  -HSync +Vsync

On the other hand Konami Logo sequence seems to be at 256 224, the screen as correct aspect but pixels are not good.

Yes, now that you mention that, it's clearly an issue with in-game mode switching not working. However, your log doesn't even show a mode change during game, but maybe it's because you exited too early to catch the change. Could you confirm this by a running a longer log? I want to check whether it's sdl not being able to switch modes (I don't remember what was the current state of this as things tend to break on Linux every few months) or it's actually Swichres not catching the mode change.

In either case, you may bypass the issue by using super resolutions (set -resolution 2560x0)

The mode switch is certainly not catched, for whatever reason. I'll need to check this. God knows how long this has been broken.

About 2056x0 resolution:


About resolution switch,  maybe the mame genesis driver is broken ? I can test another driver (arcade game or other) which has resolution switch if you know one..

Thank you for your help Calamity.

**EDIT**: Maybe the strange 2056x0 ratio is a bug in nvidia binary drivers. I'll try with nouveau. However it has nothing to do with initial bug as i tried with both drivers with same results.

About 2056x0 resolution:

I don't understand why it picks 2560x224, while in theory you're using the arcade_31 preset. It should be scaling the vertical by 2. I'd need to see a log to figure out what it's doing.

Genesis driver is fine. It's a bug with the sdl build. Anyway the last log you posted was from Konami, not Genesis.

No, it has nothing to do with that.

command line:

./mame64 -resolution 2560x0 genesis contra &> /tmp/groovymame-genesis-contra.txt

Logs are attached.

Note: -aspect is set to 4:3. Here are the result when set to auto:

To avoid confusion, it is the Genesis (US megadrive) game "contra" (which is a Konami game).

-aspect 4:3 is compulsory on GA due to how the desktop is configured (we'd need to set by default in the cd), so don't touch that.

I'm seeing an issue with super resolutions on Linux & 31 kHz (one case I had never tested).

By now, I believe using -resolution 2560x480 should fix it.

It is far too slow to be playable but the screen resolution is OK. My nvidia card is a PCI-e 1x, i believe this resolution is simply too high for my system.

Anyway, GM works pretty well for most of the Mame drivers i use so i'm happy with that.

By the way i can run tests to debug "in-game resolution switch" and "2560x0 resolution" issues above in Linux if it could help. Let me know.

Again thanks for your help.
