@tdelios Just a single file per MAME version/folder, a lot less annoying than changing the core for every single game using the UI menus.
And no, there is no plan to split MAME into version.
Recalbox is currently supporting AdvanceMame, MAME2000, 2003, 2003+, 2010 and 2015 (maybe more in the future). It would be even more confusing than having a single folder.

Here may be of help

@clonedevil Hi,

This is not possible yet, but we're thinking about such a feature.

oui 512 cpu/système et 512 gpu
pour la n64 ça dépend des jeux. Des basics genre super mario 64, mario kart etc... ça tourne bien.
il faudrait une archive de support pour regarder ta config.
