It is not exactly the same, however the PS1 emulator in Vita is based on the PSP one (they updated the emulator to improve compatibility and stuff, and it seems that the Vita version has access to a greater CPU speed).

Why? Because the CPU of PSP (MIPS) uses the same architecture of PS1, while Vita uses a different architecture (ARM), so emulating PS1 on PSP is more efficient than emulating PS1 on Vita. And Vita already had to include the original PSP processor anyway to run PSP stuff, so why to write a completely emulator from scratch if you can use the PSP one?

    I rather enjoy a life of taking it easy. I haven't reached that life yet though.

    @SylverReZ, atleast wiimmfii went fine although people only use it for Mario kart Wii
  • SylverReZ @ SylverReZ:
    At least if they ban you for cheating, get another Wii. They're cheap as chips.

    Remember when RiiShop was a thing?
  • BakerMan @ BakerMan:
    not really
  • SylverReZ @ SylverReZ:
    It got shutdown because somebody "accidentally" leaked the database for the amount of people using the beta.
  • SylverReZ @ SylverReZ:
    RiiShop is the laziest way of downloading Wii games. Did somebody not think of this through?
  • BakerMan @ BakerMan:
    although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
  • SylverReZ @ SylverReZ:
    @BakerMan, I think you're talking about the recovery mode that the SaveMii used, and also was to restore softbricked systems.
  • SylverReZ @ SylverReZ:
    If your NAND was hardbricked, then just buy another Wii. Or go with the dirty NAND flasher method.
  • BakerMan @ BakerMan:
    and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
  • Xdqwerty @ Xdqwerty:
    Brb
  • SylverReZ @ SylverReZ:
    @BakerMan, Oh yeah, that was a thing too. Dolphin does support Wiimmfi.
  • BakerMan @ BakerMan:
    yeah you just need to put your NAND backup with wiimmfi on it
  • BakerMan @ BakerMan:
    ngl i feel like if a bunch of my friends have wiis and know how to get wiimmfi and back up their NAND, then we could do a PMEX Remix tournament
  • BakerMan @ BakerMan:
    maybe even add UMVC3/DBFZ and make it a biathlon/triathlon
