Cape Mario works for me. The FS works fine.
it dont worked for me and afew others (also why SMBZ mario needed a new FS since it is built from that Psa)
I didn't actually have a problem with the FS freezing when I used it strangely. And besides, surely if we want to have a nice proper tourney, we wouldn't even use Final Smashes? Barring that it's a great PSA. Heck half your SMBZ Mario was based upon that.
i think vontower edited the bone to where FS fire spawn or something like that but anyway it crashes for some and not for some others
