PAL and NTSC have different resolutions.
Perhaps when you are running PAL games, the screen output is resized to fit the extra vertical lines (576) onto the screen and that 'squishes' in the sides a bit. NTSC only has 480 lines.

You can probably eliminate the top/bottom black bars with overscan settings, but it seems like the left/right bars will likely always be there when playing a PAL game.

@williamcaput said in Megadrive ROM language select:

RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.6.1

The 4.6.0 series had EmulationStation at version 2.9.1, your log shows an much older version (2.6.1) is in use. Are you sure you're using RetroPie 4.6.1 ?

The log shows the ROM files are launched fine. I would check the ROM files as @windg suggested and maybe post a verbose log from launching with lr-picodrive. Use pastebin.com for the output, since they're quite large.

@sleve_mcdichael said in Stand-alone Genesis rom dir:

I don't know why you'd want to update an existing link actually, except for that's how it currently does

Then it falls back to a design decision/principle of the inventors: Does RetroPie-Setup follow a "desired state" approach (=always recreate symlink) or does it have some tolerations (=if existing leave untouched)?

Better letter-crown positioning.

@sleve_mcdichael now when I try and connect to my Pi from my PC using ssh pi@retropie.local (which you helpfully advised in another post) it just opens a black box for 3 seconds which then disappears before I can do anything. My PC and Pi are on the same network.

@Floob stupid pandemic. One day though, you never know.

Hello All,
I'm dealing today with the same issue but my investigation shows so far that for me it is only related to PAL MD games

I opened a separate threat here with some more research : https://retropie.org.uk/forum/topic/34696/megadrive-50hz-games-with-genesis

The problem that I have if I use 1980 x 1020 @ 50Hz is that the monitor for whatever reason has black borders all around and I experience this on PI4B

@yfzdude cheers dude. Helpful stuff

Look like you copied a gamelist.xml from another system, which is configured with genesis instead of megadrive. What exactly did you change before you got this message ?

@sleve_mcdichael

Default will skip roms that have any piece of data from this source, and “only missing” will skip roms that have any piece of data from any source?

Yes, I had actually forgotten that point, it's quite an important distinction.

And you're welcome. Have fun with it!

@quicksilver I can do VERY minor graphic changes. I'll have to take a look at where that's at and see about changing it.

@dankcushions yes! I did the change when I found this new emulator was ported to libretro. At the end I found that the main problem in my lr-genesis-plus-gx performance is the bilinear filter. If I turn it off it's working 58-60 fps with very good sound quality. So as I see it maybe I overloaded my raspberry pi 3B too much, if I'm correct is definitely something to have in mind if you dont have a rpi3B+ or rpi4. SegaCD is working fine too now!

I'm having a similar issue with Sega CD / lr-genesis-plus-gx on the pi4. My files are .chd format. Worked in my previous build, verified the BIOS against the official documentation... nothing.

@lekzerum Any chance you could throw that file in a google drive link for me to try?

As @YFZdude mentioned, the genesis folder is a symlink (shortcut) to the megadrive folder, so there's no need to remove it - it's not actually taking any space. You can leave it as is, it's ok - the scriptmodules expect a megadrive ROM folder and updating the MD emulators will re-create the folder.

We could make it the default, since ScreenScraper is the default scraper in EmulationStation it didn't have such a great impact. The change required some code changes in EmulationStation for ScreenScraper, so that's why it wasn't added after the issue was reported.
