gcz to iso

[Gamerdactyl]

I was trying to play Smash Brawl with project +, but project + requires Brawl to be an iso, but my brawl is 2 seperate gcz files and it only works with an iso, how can I convert my gcz files to one iso?

I don't see why Project+ would require Brawl to be an ISO, but regardless, it shouldn't be too hard to convert from GCZ to ISO.

I have no idea how your Brawl could be two separate GCZ files, though. It should only be one file. What are the names and sizes of the two files? How does running Brawl from these two files work?
