@substring said in [SOFT] Arcade Manager : install overlays and manage roms in a user-friendly, fast and cross-platform GUI:
@cosmo0 i dont mean "rebuild", i mean simply check if the rom is valid
No, sorry.
First, because CLR Mame Pro already does that, and it works under all platforms (using Wine for Mac/Linux). Despite the... complicated interface, I'm not a fan of doing things that have already been done.
And second, because this tool was designed for Retropie at the beginning, and this feature wouldn't make sense in Retropie, between the "arcade" folder, the multiple MAME versions, etc. As you're probably aware, Retropie is... complicated 
I might do it in a later version, though, it's not really complicated (open a zip file, checksum the files inside, check against data in an XML...).
