PSP to PS2/PS3 connectivity emulation (via pcsx2/rpcs3)

[ghost]

This is a feature that lets you connect a PSP to either a PS2 or PS3 so you could get more content or transfer saves to/from them.
There is a partial list here for PSP to PS2 : https://www.reddit.com/r/ps2/comments/atwi34/list_of_ps2_games_with_psp_connectivity/
Didn't find a list for PS3 games but there are some that could connect to a PSP.
I know that Dolphin does something similar for GBA to GC connection by using VBA-M .
The PSP connect to the PS2 via the USB port.

PSP to PS3 connectivity is used for Hatsune Miku: Project DIVA Dreamy Theater which can be played on PSP Project Diva games on a PS3 But it requires a PSP connected to a PS3.

[ghost]

Well there is an issue open on rpcs3 side which lists some games : RPCS3/rpcs3#4119
I didn't find any corresponding issue on PCSX2 side though.

I'm less sure about PS3, since there was very limited remote play support, but I think PS2 "connectivity" was just importing save data on the memory stick. I think it DID support this via USB, but it'd be simpler (especially for Android) if the PS2 emulator just exports a file for you to put in PSP/ somewhere.

It's also possible some of these used online features that are no longer available.

For PS3 it was also about transfering saves and modifying them.

For GTPSP, you can upload transfer favorite cars to GT5's Arcade Mode to a section called "Portable Garage".

For Crash Tag Team Racing, You can connect the PSP to PS2 to unlock exclusive cars and battle arenas.

Interesting thing about Resistance Retribution it got unique features when connected to a ps3 or the TV while playing R2 .
Too bad the game is not working properly on PPSSPP.

[inukaze]

Someone had Explanation or Cheats for example to Unlock Outrun 2006 Content in the PSP version ?

[ghost]

Does USB count as networking?
I think this might be more simple then adhoc/infrastructure etc but maybe I am wrong.

[unknownbrackets]

Well, USB is implemented as its own API and special device on the PSP. It's not related to any of the networking APIs.

It's also a bit annoying to debug, because the tooling we use to create automated tests and examine blackbox PSP firmware behavior operates and communicates with a PC via USB - so testing the APIs, parameters, error codes, etc. means doing it a slower way.

I've only seen games do this via save data, but I've heard since my last comment about games doing it via a live USB connection.

[anr2me]

Just a reference of what kind of USB devices can be emulated on PCSX2
https://forums.pcsx2.net/Thread-Qemu-USB-plugin-formerly-known-as-USBqemu-wheel
https://github.com/jackun/USBqemu-wheel

[ghost]

Yeah on PCSX2 the USB side (peraphials etc) is emulated almost 100% well.
Not sure about RPCS3 but it also emulates some USB stuff properly :
https://wiki.rpcs3.net/index.php?title=Help:Peripherals_and_accessories

very few PS3 games uses the USB connection (like Assassin's Creed: Bloodlines) though.

Some further info that I found (from JPCSP repo):

Lol

Yes thanks for the link.
I saw that you contribued code for usb emulation on rpcs3/pcsx2.
Would it be mangable to emulate it on either JPCSP or PPSSPP any time soon?

For reference since you didn't mention an example, Daxter requires a live connection to Jak X for the secret content to exchange

[ghost]

JPCSP got a bit further now with it's draft implementation (I have made an issue request there too).

If someone is interested to look at.

[mitch03]

any news on this?

[anr2me]

nobody working on it (yet?) AFAIK, if there are some changes related to this, someone will probably post it here

[LunaMoo]

It's much easier to just unlock those things by cheats or plugins and for some more popular games those already exist. No game actually downloads anything from the other console, it's just an advertisement to get the game on multiply platforms and all of the "extra content" exists on the disc from the start.

Some games got it for transferring progress though from ps2 to psp which would be nice if you did start a game on ps2 or pcsx2 and wanna play it on your psp/ppsspp afterwards (could be that you wanna sell your console/PC or/and you wanna play it on the go on Android/IOS).
But yeah it does sounds niche enough.

[agent13]

Monster Hunter 2 have connectivity with Monster Hunter Portable. You can unlock the monster Yian Garuga quest on MH2 village and other bonus:

This would be very useful for the PES scene.

As you maybe know, Pro Evolution Soccer games lack a lot of licences (kits, emblems, ...).

There are communities (ex : EvoWeb, ...) where we create option files to update all unlicensed things (player names, kits, ...) to improve the overall game experience.

There is no utility to convert these PS2 option files to PSP option files. The only way is to connect a PSP to a PS2 and use the in-game feature to transfer the modifications contained in the PS2 option file to the PSP one.

Having the connectivity from PCSX to PSP (real hardware) or maybe to PPSSPP would really be awesome and help the PES scene.

[StillPlay2]

This is especially needed for WWE Smackdown Vs Raw 2006 were the PSP/PS2 versions are linked up to unlock Jake 'The Snake' Roberts. PCSX2 & PPSSPP connectivity would be an amazing feature, similar to Dolphin/mGBA in regards 😃😊

[LunaMoo]

especially needed for (..) unlock

Nah.
I mean I understand the way of thinking "game I like is the most important", however "unlocking" stuff can be done with basic cheats or memory editing, if such doesn't already exist it just means not enough people cared or even knew there's some hidden stuff to unlock.

The whole connectivity between few completely different emulation projects while cool and might happen someday requires far more effort than simply making some cheats or even injecting some stats into the game memory directly then saving it.

[hrydgard]

Yeah this would be cool but the amount of gain for the amount of effort would be very, very small. So it's unlikely much effort will be spent in this direction soon.

[anr2me]

Another approach may be, by creating a plugin on PSP, PS2, and PS3 sides (that can works with emulators too) that hooks on some sceIo syscalls and intercept any access to usbpspcm devices (ie. Resistance Retribution might be using usbpspcm0: instead of usbpspcm:) and transmit the data it read/writes over TCP/IP (ie. plugin to plugin communication).
We will also need to make sure the game detects a usb connection by faking it so it can progresses to reading/writing data on it.

[LunaMoo]

usbpspcm0 is only used by that Resistance Retribution plugin as fake ID, probably only changed to recognize it from other syscall, the game normally calls usbpspcm

E[SCEIO]: HLE\sceIo.cpp:2086 UNIMPL sceIoDevctl("usbpspcm:", 03415001, 08ed48a0, 4, 00000000, 0)

[anr2me]

yeah, anything that starts with usbpspcm should be treated as usb connectivity for games

[Florin9doi]

Rpcs3 has now support to connect real PSPs : RPCS3/rpcs3#15540
