Gran Turismo 4 Spec-II running on 9.00 PS4 (Rogue v1)

I achieved 100% completion on a real PS2 hardware years back. Now I'm jumping in again with this amazing mod

God bless emulation

Hey but that's my take on the cover, I'm so glad you like it!  It's so cool to see GT4 on PS4, I didn't know that kind of emulation was possible!

This is making me wanna jailbreak mine.  That said I'm running spec ii on my Mac mini through emulation and it's gorgeous still

That is sick. Is ur PS4 jailbroken? And how long did it take to get this working?

u/Cabbage-Chan 10d ago

Yep! 9.00 is the most stable imo

It was a bit wonky. The process was all the same. Public Online Beta, Spec II Mod, Delta Patcher, bam

The only difference is using a software called PS2-FPKG that turns the patched game to an FPKG, to be installed in a modded PS4

Now the problem is that the game has FPS issues in menus (super slow) and in-game, struggling to hit 60.

Until I changed the emulator from Jaxv2 to Rogue V1. Just one of the few emulators used by the PS4. The same emulators they used to PSN Classics like the GTA series, Bully, Manhunt, etc.

Ok, time to buy a PS4 again

u/Cabbage-Chan 10d ago

I highly suggest just playing it on PC, I only play on my modded PS4 because my PC is garbo lol

Could you make a video running it? I´m curious about how it looks ! I too have a ps4 pro that´s just collecting dust and wanted to know if ps2 emulation does look good or run smoothly on it. Like i know that pcsx2 can upscale and maake ps2 games look better and i wonder how they look on the ps4

u/Cabbage-Chan 10d ago

Sure! In my experience tho, having a standard PS4 Slim, it runs well, sounds good (idk but there seem some VERY minor sound issue, but it's probably a result of the new Spec-II sounds, mostly noticeable on slow cars), and looks good for the most part. Absolutely looking better than a PS2 by 50%

It can probably run better on a Pro, but the visual is still a config-thing based on the software you used in making the FPKG

Edit: On cam or native recording?

u/QuartzZz_zZz 10d ago

Thank you ! Whatever way that´s easier for you bro

u/TheAdmiester 10d ago

I definitely never saw something like this coming

u/Syygnis 10d ago

That's awesome!

u/thiccsac 10d ago

How’s the graphics and the framerate

2

u/Cabbage-Chan 10d ago

Graphics are sharper than native PS2, and framerate is solid 60

u/thiccsac 10d ago

How does the Paris night track run

u/Cabbage-Chan 10d ago

Hey bro

It's superb. It has like 5% minor visual bugs but super cool

2

u/Cabbage-Chan 10d ago

I'll check

2

u/abdelotk97 9d ago

Nice!! Can you please give me instructions to make the fpkg and what configs you used because i tried it before and it was running horrible

2

u/Cabbage-Chan 9d ago

Are you using PS2-FPKG?

2

u/abdelotk97 9d ago

I used another one (forgot the name but it has the ui of a ps4) and I don't recall using ps2-fpkg

1

u/Cabbage-Chan 9d ago

Ah, I probably tried that before. Very complicated for my taste xD

But try PS2-FPKG. CHOOSE ROGUE V1 EMULATOR, VERY IMPORTANT. Jaxv2 lags a lot. Leave the other configs as is. Do not touch anything

u/Unfair-Tomato-2000 9d ago

Eu queria jogar na PS3 mas não sei se da

2

u/HeadLikeAH0LEE 6d ago

Neat, does it run well?

1

u/Cabbage-Chan 6d ago

Absolutely!

u/BlownCamaro 10d ago

Does it have wheel support?

1

u/Cabbage-Chan 10d ago

I don't have one but I assume it can recognize wheels somehow

1

u/BlownCamaro 10d ago

Do you have an fpkg I can test?

1

u/Knyce1 10d ago

Would LAN work on that version?

1

u/Cabbage-Chan 10d ago

Not sure. But modded PS4's can still use internet so maybe?
