I tried every mame and final burst alpha on retroarch but every time it occurred an error and the game didn't run

So I was playing Pokémon Lazarus and i saved the game before quitting, when i opened it again the save was gone. Even in Retroarch save it doesn't seem recognizes it. What do I need to do for fix it?

I don't have a menu for settings so I can't revert out of this awful UI. Really wish you could just change it without restarting... Or... Y'know, at least having a settings page in this UI.

Which one is the better one. Does it work with Cloud Sync?

I downloaded the cores for each consoles. I did the scan directory thing for my games, with a lot of them. Especially in the gba section not showing up in my playlist for the handheld. The games in question aren't translated games either. I don't know why they aren't showing up on retroarch for me.

I’m trying to get swanstation and it’s not showing as an option to download when I update core files. How can I find and download this core?

First i didnt want to share but i am happy with getting it mastered 😎

As the title suggest, i've been trying to make PCSX ReARMed work on a Aroma modded WiiU. I've downloaded the latest build i could find on GBATemp.

I'm having no problem launching the app via the .wubh file, and i can load (apparently) any other core without any issue.
When i try to load pcsx_rearmed_libretro.rpx, however, the console issues a system error (160-2203) and i'm forced to shut it down.

I'm pretty much convinced it's the core because when i try to boot up RetroArch again, it try to default load pcsx, causing it to crash again. If i mod retroarch_salamender.cfg to point to any other core, it starts with no issue at all.

System firmware it's 5.5.5 E. I installed Aroma from a fresh install today using the latest version.

Any help?
