Obligatory mention of Kaze, who has spent the past several years optimizing Mario64 using a variety of interesting methods. Worth a watch if your interests are at the intersection of vintage gaming and programming.

I was just about to post his video from August explaining how much excess ram mario 64 uses and where, which was the first serious mention I saw of a ps1 port being possible. He uses the ps1's smaller ram size as a kind of benchmark.

I did not expect it to happen so soon.

He's great. (And ripped!)

I wonder what someone who has PS1 knowledge equivalent to Kaze's N64 knowledge could do on that console---perhaps using Mario 32 as the benchmark.

(Mario 32 = Mario 64 on PS1.)
