Thanks for all the suggestions. I should have no problem scraping the region artwork I'm after now.

@windg said in Extract region of games via command line:

You can take the hash of the rom and compare it with a database. For example this site : http://redump.org/ have the hashes of the games of a lot disk systems.

Unfortunately that site does not have retro games listed. Only PSX, Dreamcast and up. However the m5 hash approach gave me an idea: I can download a rom pack and compare my roms to the ones from the pack. Thanks for your helpful answer! :-)

Thanks for all your help everyone. This has helped me learn a lot!

It looks like maybe I could mess with mame.ini if I want to try to configure this, though I haven’t quite yet determined if that works for lr-mame2003.

Anyway, seems like maybe the right way to play this particular game is with a different emulator anyway!

Thanks.

'ss' is the internal one used by ScreenScraper. So it's not a region per-se. I am actually not sure what they use it for.

EDIT: I have pretty much all of them in my Skyscraper docs here. Skyscraper uses an internal region priority list as documented there. It will also auto-detect regions based on the filename. Also documented at that link.

Yes, after comparing the SNES bezels *.png names with all SNES roms and swapping the roms with the correct versions I also realized the bezels are about 95% for USA versions and rarely for Europe or Japan versions of games.
Thanks!

@mitu said in Regional dependencies on ROMs across different emulators:

The emulator should be able to scale it to your native TV screen's resolution.
EDIT: What I've other people recommend - and it sort of makes sense - is to try and run the NTSC version of a ROM when possible. NTSC ran at almost 60hz, similar to the modern displays.

Bingo - that's exactly what I just did before I'm reading this :-)
Set boot config to CEA-4, removed default emulator video choice from on-game startup menu and sorted out my ROMs so now it's all USA (NTSC) versions.
Now it's all perfect.
As always: Thanks buddy for your good explanation and clarification.

You want to rename the roms to remove region, or remove the roms that are not of your region ?
The first is basically not possible, because you can't have 2 files with the same name in the same directory :) You may batch rename them if you want, but can't simply remove the region.
The second options is also feasible, but we would need more informations.

Anyway, @BobHarris suggestion or scapping is the best way IMHO.

On NES games the music plays way too fast, and on SNES games, there are minor issues with the sound.

I can't speak to the SNES issues, but I believe both lr-fceumm and lr-nestopia need to be aware that a game is PAL before they will play at the correct speed. If I remember correctly, lr-nestopia achieves this by checking the NstDatabase.xml file in your BIOS folder and lr-fceumm checks for "PAL" to be included in the file name. Outside of that, you can also force PAL from the core options in the RetroArch menu as well.

@jonnykesh I tried a few combinations and it seems "Generic 102-key (Intl')" with "English-US" is the one to use.
Thanks for helping!

Question 1 sorted by getting no intro sets and cleaning it up manually, bit easier than regular sets.

Will bump this once to see if anyone has solutions to question 2

@lostless what if i disconnect the wifi? maybe it would stress it less?
