So Far tested some games that use to give me issues:
Cruis'n USA - works perfect, no more slowdowns and audio glitches
Cruis'n Exotica - works perfect, no more anoying texture that follows you when you drive.
Hydro Thunder: Can finally Hear sound and music. Minor Issue; at boat select screen, water appears as a green background
Legend of Zelda Ocarina of Time: Don't need that delay cheat anymore to access inventory.(playing the game on the n64 console is still a bit faster to acess the inventory, buts good enough)
Mortal Kombat Trilogy:No more Slowdowns or Audio glitches, has a minor bug;the cursor is kinda glitchy at the character select screen.
All tested with PJ64's default plugins, more to test tommorrow.
