I just wanted to stop by and say that PSA is working just fine also. No problems over here! Happy smashing and thanks again!!

Holy cow it does work!! Thank you so much!! You both have been a big help. I'm so stoked about this you don't even know. I was about to dual boot and install windows XP... haha Thank god I didn't go ahead and do that.

Now I'm a complete noob with Brawl Editor and PSA but I have 4 very specific characters I want to make. I know I've got a long road ahead of me haha It will take some time to figure it all out but at least I've actually got the tools do to so now. Thanks again to the both of you!

I've managed to get all 7 parts concated and I unzipped the BrawlBox.7z data. After that I got the BrawlBox WineSkin app. I double click it and nothing happens so I held option + double click Here I get Install Software, Set Screen Options, Advanced, and Quit. I try installing it to a setup .exe to the C Drive but I get this "Oops! No new executable found! Maybe the installer failed...?" So maybe I didn't install it properly to C Drive?
I'm pretty new to this wineskin stuff too so any help would be appreciated! Thanks guys

This thread is very helpful. Another Mac user here. Hoping to get BrawlBox and PSA working on Mac. I plan on trying to get it working on my Macbook ASAP. Please keep the thread updated! Thanks
