Just for the stats: I'm on a EUR console, tried all V3 files posted here, as well as Sonic's site and the raaaw one, and I consistently get 'memory allocation failed'.
Sorry I thought this was reddit. OT: I'm on 5.4.0, but don't have SSB so eagerly awaiting Loadiine with MiiMaker support for 5.4.0. Or whatever surprises Hykem has for us ;-)
