@GreenHawk84 please provide a verbose log for a game with the issue. suspect you have issues with bad override files.

Went to /dev/shm/runcommand.log after running Streets of Rage 2:
Parameters:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-genesis-plus-gx/genesis_plus_gx_libretro.so --config /opt/retropie/configs/megadrive/retroarch.cfg "/home/pi/RetroPie/roms/megadrive/Streets of Rage 2 USA.md" --appendconfig /dev/shm/retroarch.cfg
[CDROM] No sg devices found and sg kernel module is not loaded.Then I ran a Mortal Kombat game and the issue did not appear:
Parameters:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-genesis-plus-gx/genesis_plus_gx_libretro.so --config /opt/retropie/configs/megadrive/retroarch.cfg "/home/pi/RetroPie/roms/megadrive/Ultimate Mortal Kombat Trilogy.md" --appendconfig /dev/shm/retroarch.cfg
[CDROM] No sg devices found and sg kernel module is not loaded. -
@dankcushions it seems to be intermittent. I loaded the Mortal Kombat game again and it did the weird display.

@GreenHawk84 Enable verbose logging in the Runcommand launch menu, this should add more information in the log.

Hello, I uploaded the file with logging, it did it upon first load of Robocop vs. Terminator:
https://1drv.ms/u/s!AluYjzvuXNufjgfHyEkBpRElX1bn
Here is a file for X-men which did NOT do it on first load up:
-
I tried to update Genesis-GX from source but no fix. I started X-men and it did not do the issue, exited, entered X-men 2 and the issue appeared, then went back to X-men and it was there. So something is getting mixed up.

[INFO] [Overrides] core-specific overrides found at /home/pi/.config/retroarch/config/Genesis Plus GX/Genesis Plus GX.cfgplease post

/opt/retropie/configs/megadrive/retroarch.cfg -
@dankcushions @mitu here are the files:
-
I changed the default Master System emulator to Picodrive and the problem went away. So it is definitely something that went wrong with Genesis-GX. The problem is I prefer to use Genesis-GX.
-
@GreenHawk84 You have an overlay set and a custom viewport for the core, which partly explains the issue, though I don't understand why it behaves differently based on the game.
You can try to rename the
.cfgfile for the core (Genesis Plus GX.cfg), then add the overlay configuration in/opt/retropie/configs/megadrive/retroarch.cfginput_overlay = "~/.config/retroarch/overlay/genesis.cfg" input_overlay_enable = "true" -
@mitu I noticed the custom display port set in Genesis-GX but I never set that. I haven't touched anything else other than setting up the overlays which worked for years. I updated this one time and it started doing this.
Is there a way to just remove the display port? What was the default for that setting?

The default is to not have those settings and it will work fine, but your overlay might not work.
-
I wonder if this Core was updated and changed a setting along the way.
-
@GreenHawk84 Core specific settings are not stored in the
retroarch.cfgfile, but in the options file (/opt/retropie/configs/all/retroarch-core-options.cfg). There might have been some changes to the core that would affect the video display (viewport).Try to re-do the setup for the overlay and see if you manage to get it working as before.
-
@mitu I went in and removed Genesis-GX and installed from binary just in case. I also located the Genesis-GX override and deleted it. Games display properly without overlays applied (black side bars). If I save an overlay, they do the odd viewport. I uploaded Alienstorm's game override file here:
https://1drv.ms/u/s!AluYjzvuXNufjg8y76QZyWCzCz5d?e=UsKPcC
This never use to happen, so where are these overrides getting the viewport setting from? I never ever set a custom viewport in my years of using Retropie.
-
I think that the custom viewport might be added by the overlay - is there a way to get the overlay you're using ? What's your monitor/TV resolution ?
-
Hello @mitu, I really appreciate your help here.
I uploaded the overlay file and the .cfg associated with Alienstorm:
https://1drv.ms/u/s!AluYjzvuXNufjhOPYuwPii8rTQVm?e=GK2abP
https://1drv.ms/u/s!AluYjzvuXNufjhSeJv6xpE4g9lMQ?e=mrSrmy
@mitu my resolution is 1920x1080.
-
I basically started from zero by loading Genesis-GX without any overrides, just stock settings, and the video displayed normally. I started up Streets of Rage 3 and applied my overlay for that game and it displayed normally during the session. I saved it as a "Game override" and then exited. When I reloaded the game, the overlay loaded, and the issue appeared. So something is setting up this issue in the override .cfg file. I have no idea where it is coming from or how to reverse it so I can get my Sega games looking normally with an overlay applied.
-
I have always set my aspect ratio to "core" for everything I have ever done in Retropie, but I am noticing that it wants to revert to "custom":
Perhaps this is causing something? I have never once set anything to custom aspect ratio.
-
It's strange, but I cannot reproduce this reliably. I've repeatedly started from scratch, loaded the overlay then saved the game override. The next start, it might show the strange resolution or not, but if I exit and then start again a few times, the screen is right (overlay + game).
I certainly bumped into the same issue as yours, I don't think the viewport settings are at stake.
Can you reliably reproduce this, even if you restart the game after saving the game overrides ?
