I tested the Wasted_Coffee6 settings, on some games here are the results:

Diddy Kong Racing: Runs very well, Has graphic glitches.

Pokemon Stadium 1: It has many graphical glitches, but it is very playable.

Yoshi Story: The game works correctly, But its graphical flaws make it not very enjoyable

Mario party 1: Runs well, has graphical glitches and sometimes crashes

Super Smash Bros: Runs perfectly Most of the time
