Ps3 slim playing ps2 games online

Any luck yet? I know only a bc ps3 can play ps2 games online but I was wondering if anyone created a workaround yet for the slim to play ps2 games online yet
 
So there is no way a CFW PS3 (non BC model) can play i.e Resident evil Outbreaks online via private server???? There's absolutely no work around!?
 
No way around. Maybe if some developer reverse engineering the ps2 emulator from $ony and add emulation of network and hdd functions from the original PS2 hardware (or BIOS), maybe getting help from PCSX2 coders... Unlikely that it will happen, sad but true.

Thank you very much for the reply an clarification.
 
@sandungas Maybe you can give me some light about this subject, I'm curious, I was searching the internet about this post PS3 Slim + PS2 Games online and it me lead to this topic in PCSX2 --> Does a backwards compatible PS3 contain a ps2 bios?

The quotes below gave me some attention:

Have you tried that? Or anybody else?

I don't think that a 'normal' ps2-bios version should be inside the ps3 bios as the ps3 is just not a ps2. It has different hardware. The bios is for communicating with the hardware. I really think it should be different on the ps3..

I would guess the largest part of the ps2 bios on the ps2 and on the ps3 are equivalent. But I guess especially the important hw interface stuff is quite different.

Actually, any PS3 console contains complete PS2 bios, look in /dev_flash/ps1emu/ps1_rom.bin, that is actually PS2 bios, but you need to add dummy bytes in end, to make it's size 4,194,304 bytes, then PCSX2 will recognize it

I already tried that, also ps2 emulator .self's inside ps2emu folder contains cut ps2 bios, which works on PCSX2 only using "Boot CDVD (fast)" mode. PCSX2 detects ps1rom.bin as "USA v1.90 (23/06/2003)".

So I was thinking, if using a real and complete PS2 BIOS dump and inserting it in PS3 or in ps2 emulator self, would us restore some PS2 functions on NON-BC PS3? Like Network play, HDD installs... or maybe just more compatibility with PS2 games? Has anyone tried to do something like that?

PS2 bios won't fit into emulators used in PS3. I injected custom bios, but is pita to do so. You need to replace RDRAM module to one from netemu bios, and cut off unused modules (so literally repack bios). Anyway, that won't help with net features. You need to emulate that to make it work, bios is not enough. I suggest you using pcsx2 if you own pc that can run it. Netemu probably never gonna have net play support.
 
What @kozarovv said :D
I never took a look at it, but the PS2 bios is inside the ps2_netemu.self, to replace it is needed to extract it, rebuild it, and inject it, but without exceeding the size of the original, so if we want to add something is needed to remove something

And i guess the emulator itself needs to support it, also the PS3 fimware too because is needed to create some kind of "bridge" in between the network adapter of the PS2 (emulated) and the network chip of the PS3 motherboard
 
Thanks for the replies and even addressing this issue everyone. We made it this far with the ps3, and I can only hope there will be a work around to this issue so we can all play our old ps2 games online on the slim one day. Again thank you

It is PSX firmware, not PS2 firmware.
 
The PS1 emulation in the PS3 is based around the DECKARD's PS1 emulator from the 7500x+ models. That is why it is a PS2 BIOS labeled as a PS1 one.

You're both partially wrong (or partially right). This is ps2 rom STRIPPED from ps2 functionality. So i really doubt you can run any ps2 game correctly on it as stated, being detected by pcsx2 doesn't mean it run fine. Pcsx2 just read romver, and have no clue what's inside before running game on it. This is probably the same bios as used in xperia play. Where you also had ps2 stripped rom to run psx mode as described by Yifan. ;)
 
The stripped ps1_rom.bin has been introduced in the later firmware versions. Earlier it was a plain PS2 BOOT ROM, wasn't it?
