sorrycostello said:Not everyone knows, but the PSP is actually dual core although the second core (the MediaEngine) only has limited access to the other hardware. Not all emulators take advantage of the second core as it's tricky to use, but it does mean it's unlikely for a PSX emulator to be full speed on the DSTWO although not impossible.
I don't know how many times it needs to be said, but POPS IS NOT AN EMULATOR. There is no need to emulate a PS1 on the PSP because the CPU is the same, all you have to do is virtualize the hardware. Yes, it is tricky without a MMU but VMware and Virtualbox do it on the x86 and the x86 is not normally virtualizable (i.e. the MMU is not very helpful so it has to be done in software).
