Mame delegating different region or older versions of a game help.


Recommended Posts

Hey guys I'm cleaning up my mame non merged set to save space. When I'm deleting a game that has Japan Asia and other countries. And I want to save the us version only. After I expanded the grouped games to show their individual versions. I select the ones I don't want and only leave the us version. I hit delete and Launchbox asks do you want to delete the 4 games for example. Then do you want to delete the roms for those 4 games this can't be undone. Then after that it asks " would you like to delete additional application roms as well " ? What does that mean didn't it already delete the roms ? And if I hit yes does it mess anything up for the remaining us game that did not get deleted?? PXL_20240515_131822999_MP.thumb.jpg.5e74d96f379e726156c7c31cb004cdd5.jpg

Speculating here...

What may have happened is, when you expanded the games, that info was still cached (not yet written to the xml file).  And when you when to delete the other files, it 'thought' there were still additional apps.  So at the "would you like to delete additional application ROMs as well" prompt, I'd select "No".

OR... it doesn't actually check for additional apps, and just puts that message up 'just in case'.

Thank you for the info.

You should never use that functionality for a MAME set unless you have a non-merged set. If you are running split or merged which files you can safely delete is wildly different that non-merged.

Yes of course I'm using the non merged set.

you can safely delete those if that is what you wanted to do. Non-Merge the only clean way to go about it.  Reason you get the additional apps message, is because Launchbox views those other version as "addition apps". So you would only delete those roms you selected to delete.  When you right-click on the game and "Edit Metadata", you will see the additional apps on the left column, which contains the other versions of those games.  Hope that helps clarify why Launchbox put up the additional apps message.

Makes total sense. I have to try this and see if it shows it like you said. Never really noticed that before. Thank you for the info.

Bro I just tried it and man! Thank you ! This is exactly what I was looking for. The other way I was doing it when I expanded the game that has different versions. Sometimes the other versions disapeared.  Not next to the original. Then I'd find them somewhere else by the regional name. This is way faster and better to delete exactly what I wanted. Again thank you.
