Super Mario World

In Super Mario World Mario and Luigi must once again save their favorite princess as Bowser and his minions try to take their revenge on the plumber brothers in Dinosaur Land. The Super Mario series took the Super Nintendo by storm with this instant classic. This episode introduced new power ups and enemies, as well as the lovable little Yoshi and his tribe. The adventure has Mario and Luigi travel on a giant map and some levels include secret exits that will lead to hidden stages. In fact, the adventure is so rich that Super Mario World was the first Super Mario game for which Nintendo allowed players to save their progress.

also, may need to enable frame skipping, frame limit: 60, and disable scaled EFB copy for a speed improvement. now the game runs correctly. minor speed hiccups (rare microstutter), not sure if due to dual-core.

FPS
NTSC version (only tested version I have), Dolphin has to be set to 30 FPS or it will always run too fast.

(user2: cant repro this issue, using progressive scan, frame skipping and frame limit: 60)

Audio
LLE audio must be used. Due to dolphins nature when running at 30 FPS the audio will be choppy so its a trade off between too fast gameplay or choppy sound.

(user2: cannot repro this issue)

EFB Copies
you must have EFB copies to ram. I believe EFB must be set to virtual also.

(user2: cannot repro. EFb virtual only seems to slow the game down considerably, with freezes)

Menu Arrow
start menu arrow is missing from file selection.

(user2: confirmed, only first 2 options however)
