I've read forum posts somewhere from Vanity about consoles softlocking once they reach to Path when selecting either Lucas or PKMN Trainer, I understand the reasonings but then I saw he posted that the way to avoid it from softlocking was to play on a vBrawl download, I did that for 4.2, still softlocked, then i did it for 4.0bc, still softlocking. I have also softlocked in 4.0bc after defeating Porky in The Ruined Zoo. Very confused.
you can easily avoid the crash in the ruined zoo by choosing pokemon trainer over lucas. lucas crashes the game everytime upon selection there. as for the way around it, the only i found to get around it is by switching to vbrawl, completing path to the ruins there, and then switching back to b- after completing it. it's impossible to progress past the stage in brawl minus. i still have yet to find any way of preventing the crash otherwise. i've done minimal testing with it on 4.2, mainly because on console sse seems to lag a lot on versions past 4.0bc. this is the main reason emulator is the only platform that can be used for sse speedruns.
