In addition to the new Internet radio support, an unannounced extra in today’s PS3 2.10 and PSP 3.80 firmware updates is the ability the remotely play all PS One titles. Players may also play any owned PS One title from the PS3 hard drive rather than downloading the game to the PSP memory stick.
Although this unexpected bonus feature has been confirmed by GamesIndustry.biz, it’s unknown whether there are any incompatibility issue with specific titles. Certain titles will require players to reassign controls to compensate for the PSP’s lack of two analog sticks and four shoulder buttons

“PSP’s lack of two analog sticks and four shoulder buttons”
If my memory serves me the original PS1 controller didn’t have analogue sticks and only had 2 shoulder buttons so there shoulnt be any problems at all.
Well Norbit, you thought wrong. Although the original PS controller did NOT consist of analog sticks, it did have 4 shoulder buttons.
Um…in the later PSX days like when Ape Escape came out on the PSone, it did require both analog sticks to work. So some PSX games do require the analog sticks. And yes there was an L1, L2, R1, and R2 buttons.
I stand corrected. I dont know why I thought it only had 2 shoulder buttons because I can remember using my PS1 controller on the PS2 when it first came out so it must have had 4.
@ KoE_Dae’Loki. Ape Escape was ported to the PSP in 2005 so they must have go it to work somehow.
