i also use daedalusx64 i play mario64 and smash bros i hope that a new playable n64 emu come for the vita soon
A vpk installer for user of PSP save transfer method that should have an option of installing extracted VPK files this would save a lot of time because for vpk that are 4 gb there would be no need for double the space on the limited size memory card. I know VPKShrink and VitaOrganizer exist but both those methods require ftp which can be dangerous if connected to your main internet router.
More details about the ftp method is on reddit: https://www.reddit.com/r/VitaPiracy/comments/507inp/for_anyone_who_will_not_have_the_space_to_have/
but my request is a simplified method that would just require extracting the vpk to a folder on pc and transfer to Vita using PSP save method then the vpk installer would take care of the files without requiring double space.
edit- Actually it wouldn't really being installing the data, more like moving the game data to the correct folder.
This is what I am really looking forward to also.
I've been using daedalusx64 on vhbl. Some games are quite playable. Starfox, Mario64 is good as well. Ocarina of time is not playable. Messing with the settings helps a little.
Anyway, it's an option until there's an official port if you want to play.
