There's no ifs about it. I always build projects myself and gave this one a shot literally 10 minutes ago. I had to grab libz just to begin building, and then it got stuck again. If it builds, it's not with devkitpro and I wouldn't run
Just tried to build it 10 minutes ago. It doesn't build. Not with devkitpro r45, anyway. Unless you have some insight in libz configuration for devkitarm that I missed.You're wrong, it compiles just fine.
Zlib is required because update archive (TTP file) is basically ZIP archive with special header.
