So I found the issue. Turns out downloading the Github repository does not work whatsoever. I haven't tried it yet, but the Mega download has numerous files in it that aren't on Github.
The repository download is for the uncompiled mods - it's mean to be copied into the "workspace" folder for Sm4shExplorer, in case someone wants to use my mod pack as a base for their own mods. It's also for people who want to have a "nightly" version of the modpack, because I don't always update the download when I add new content on my end. I'll be sure to specify that more clearly when I update the OP next.
Vertex edited characters work fine online, not sure where you got this information from. You're thinking of model swaps (ex. Elec Man over Mega Man).
I just found this out myself. I had heard wrong some a person on GameBanana. Thanks for verifying though, I'll update the OP.
I can edit/add customs right? So this is an unpacked mod pack? Thanks BTW
It's supposed to be packed, not sure why it isn't packing them properly. If you'd like to add your own content, I'd highly recommend downloading the Github repo and putting those contents in your "workspace" folder. Future versions of this modpack will be packed properly, to improve load times.
So did anybody test this for EUR version?
Not tested on EUR, and probably won't work. I don't have the EUR version myself, so I wouldn't have a way to build or test it properly. However, if some experienced modder would like to take the files from Github and build a EUR version, I'll be more than happy to work with them to make that happen. However, it needs to be someone who knows what their doing... If I have to baby step them through the whole process, well, that's not very efficient, is it? :-/
