There's a note about that:

> Snowboard Kids 2 was written in C and compiled to MIPS machine code. The compiler was likely GCC 2.7.2 based on the instruction patterns [3]

> This is mostly just guesswork and trying different variations of compiler versions and configuration options. But it isn’t as bad as it sounds since the time period limits which compilers were plausibly used. The compiler arguments used in other, similar, games also provide a useful reference.
