Hardware How accurate is PSP "emulation" on vita ?

[Vlad_78]

Not the right topic for this post...

But to answer your question, Portable Ops, and by extension Portable Ops Plus, can't be played on the Vita for US accounts, only for EU accounts.

Thanks for answering and sorry for the wrong post! But another question would have to download it by accessing PS3 my American account and transferring to the vita ? I say this but I have ps3, if necessary with one to download

That method doesn't work with Portable Ops.

Wow my thread reached 10 000 views. Cheers. Must be from google searches.
Was there some progress in understanding how it works and its limits or are we still confused as hell? Altough yifan_lu's post made sense to me.

Yeah, as yifan said, the Vita contains a whole MIPS Allegrex R4000 on its system-on-chip, basically running all CPU instructions natively, so that statement still holds true.

Media Engine instructions are emulated through an ARM version running on the Vita’s side, and the GPU is completely emulated altogether.

The Vita also contains the whole PSP boot chain (bootrom/IPL/kernel, etc.) so those don’t need to be emulated that much either.
