This model replaces the Fiveseven weapon by Fox Mccloud's Blaster seen in Super Smash Bros Brawl.
Yeee I know, another mod about starfox but in my defense it seemed interesting to work on this model and it certainly gives me ideas for future mods
About the problems with the game...
I tried the models and they do not give me problems when using them with the exception of the p_fiveseven model.
I recommend using the mp_consistency 10 command before playing if you use the p_ model
Anyway I hope you enjoy it ;D
