I recently used my DS3 to play through Bloodstained on my PC (there are official Sony drivers for it now, no third party software required), and yeah, every time I disconnected the USB cable from the PC, my PS3 turned on. It was annoying.

The PSP-2000 and PSP-3000 don't support controllers. So you need to hold the PSP in your hands and get some component extension cables, which is not ideal compared to a dualshock 3.


The original component cable is pretty long, maybe 2.00m? 2.50m? You will have to use the PSP as a controller, but these play UMDs, if not you can install Custom Firmware on a PSPGo and call it a day, there's quite a few fan-translated games too: https://www.romhacking.net/?page=transl ... ssearch=Go

Oh you also need a PS3 to sync the Dualshock 3 to the PSPGo and you will lose the sync each time you rehook the Dualshock 3 on the PS3 needing to redo the process again, the best thing to do is get a dedicated dualshock 3 just for the PSPGo, never hook it again and use the Dualshock 3 Charging Station.


The official component cable is ridiculously short (1.7M) IMO even for a desktop setup.

I have mine gong through AA component switchboxes and then in its own cubby with the ps TV. SO I bought a 25' Component cable and a coupler

These couplers are a godsend though and can be be bought for $5 on ebay.

The PSP feels great in your hand playing on a TV but Sony's decision to place the cable in the lower right corner of the PSP instead of directly on top does feel a little awkward.

One advantage a PS TV jailbroken does have is a full screen stretch. It looks muddy but I prefer it to sharp pixels and a full black bar border.

Sony LCD TV manufactured around 2010-2015 featured a "Portable Mode" which is designed for the PSP and stretches the image edge to edge with non interger scaling albeit. I have the Sony 65W950B which was manufactured 2013.

I have never heard of the euro street ones but that sounds like the winner as I have a collection of about 40 UMD's and would love a progressive screen with a better brightness.

I have the Street, it doesn't have the interlacing of the 3000 but it doesn't have expanded color (or whatever the setting was called), so it looks a bit washed out in comparison, and it doesn't have the button for adjusting brightness, so you need to go into the menu every time you want to adjust it.

My favorite is the Go screen, and I mostly only play RPGs when on the go anyway so I don't mind the form factor much.

They started earlier than 2010, also someone posted the result here and it wasn't good at all, whereas playing PSP games on the PS TV increase pixelization by 10000 folds, the whole stretching thing on Sony TVs increases blurriness by 10000 folds, the best thing to do is either play it unstretched, play it on a pro CRT monitor and use the settings to fill the whole screen, use an XRGB-3 or use an OSSC + Extron DSC 301 HD.

A modded PSTV lets you use nearest-neighbor scaling for PSP games, and I believe the Vita has the PSP's CPU, so the emulation seems close to perfect from all the games I've tried. Looks quite sharp, wayyy better than my PSP-2000 hooked up with component.

It's been confirmed through PS Vita firmware update info that the PS Vita is using a PSP emulator, it still uses emulation.

See the teardown:

The MIPS R4000 CPU from the PSP is included in the Vita's SoC, so all CPU code is executed natively, while the GPU is emulated. IIRC the PS2 does the same with PS1 hardware.

Partial emulation is still emulation, this is why the PS Vita still relies on a PSP Emulator to run PSP games, PS2 on the other doesn't use an emulator to run PS1 games.

I guess we have to wonder how sensitive the PSP library is to emulation artifacts. I don't really know how specialized the hardware structure of the PSP is, but maybe emulation, especially when done in-house by Sony, doesn't really matter for most titles.

Never said it wasn't emulation.

Except the PS2 kind of does emulate much of the PS1:-

Which leads to a number of compatibility issues:-

Suprisingly some models of PS2 Slim wont even play certain PS2 games!
