@37:00 I was a bit confused that substracting 12 from the stack pointer (addi $sp $sp -12) helps allocate space on the stack, but then quickly found out that the stack grows "downwards" in memory 🙂 Now I get why function call can only take a limited number of arguments and otherwise you work with pointers (I guess).

Yeah, you can always store the extra arguments onto the stack before calling the function, and the function can retrieve it from the stack at the beginning.
