if the chip in the ds-x could be run at 350 mhz, it could be possible to emulate some of the less taxing games from the ps1. you have the arm7 processor, the arm9 processor, and the ds-x's processor running together to do it. would it be tricky and probably never happen? oh ya. impossible? no.
the psp is going to be running ps1 games officially, and ps1 emus are already in the works unofficially which will probably converted to hacking the official way.
you are a douche good sir.
I'm a douche? what the fuck are you talking about? Weren't you the one who was on the DS-X skins forum bitching how the DS-X team hasn't done ANYTHING to support skinners? that the forum was embarassingly DEAD?
A DS-PSP? Uhhh, through software emulation maybe.
I'm sorry, the PS1, while dated, had it's own dedicated GPU. Not something the on-board ARM9 or ARM7 is going to come close to replacing, and the seeing as the best they can do in the DS-X is an ARM7 with no RAM (and no cache), the best they can hope for is a faster DSP. Then you have to consider limitations because it's not on-board, it's on the goddamn DS-X, where I/O and transfer rates are s-l-o-w.
They have a better chance of emulating handhelds that also use ARM chipsets and use the same/similar instruction sets. like cellphones / PDA.
labelling it as "10 times the speed your DS is running at", they're setting themselves out to fail.
