On: Super Mario 64 has been decompiled

Surprising that an unoptimized build could be fast enough to not be noticed.

Their toolchain might not have been mature enough at that point for the compiler to optimize reliably. Just means they had to optimize it manually.

The SDK used the compiler from the IDO 5.3 package which was provided by SGI for developing in IRIX 5.3 (if you paid the extra for that option).

I think by then it would have already been pretty mature.
