well, not sure, might be me but is there anything that says what language a rom is? cos i opened a gba rom link read the info but i couldn't see where the language is, and is there a way to cross out all non english roms in settings? plus for the Potentially Similar Games area as well?
Um. I think most have them have the language already. They're usually abbreviated depending on what country/languagre they're in. (U)= United States, I think (E)= Europe (J)= Japanese (F)= French (K)= Korean Some others but I think you get it.
It's usually in the name of the ROM. https://www.romulation.org/forum/index.php/topic,1359.0.html ^That'll tell you all the ones you need to know and more.
They do that with all the small Retro games such as SNES's Chrono Trigger and some N64 games, with all the hacks and other language roms with them as well, but they wouldn't do it with a NDS or GBA, as they are larger in size, wasting time. If you're meaning languages inside a game, that wouldn't work, as some games are made in Japanese first, then english or something else a bit later, so if that happened, you would find it will take even longer to be released.
how about a link to filter search results? and the U E J and stuff are for countires not actually for language.....
there are the region is pretty simple if its U than usa that means english E its europe which has english too but its not their native language and so on and j japanese(region=their language)^_^
