sorry forgot to mention about this game, this is intended for free for all only at the mo, you can play team games but you only have 3 of the characters costumes to pick (this will be fixed soon) so 1 player stuff shouldnt really work like adventure mode, classic mode all star mode and the rest.
the other problems you are having are the same problem someone had in this thread
http://www.wiiso.com/showthread.php?292715-Slayers-Custom-SSBB-(V1) but they figured it out so ask them maybe as i use cfgloader so i cant advise you there but theres nothing wrong with the files and i use gc control too and everything fine for every port and it works pefectly
I can understand that. I just wanted to play some against AI, so that was my only option at the time. Excited to hopefully get everything working though!!
Thanks for the link, I'll look through now
EDIT: looked through, do I just need to add those codes in? How do I add them?
Also, will this fix the problem of not being able to play against the CPU?
