Ripping ROMs from PS2 discs

[Ghostlines]

I did a quick search on the forums and didnt see this question already asked. Is there a way to rip ROMs from a PS2 disc, for example? 

I did some searching on Metal Gear 1 and 2 that were officially translated for the MGS3 Subsistence bonus disc and the general consensus is that the ROMs probably arent running through an MSX emulator but rather using assets unique to the retail copy. Basically, no known way to extract the ROM from the disc to see if it would run through an emulator.

So with that said, I started looking into other PS2 collections like Street Fighter Alpha Anthology. Which apparently runs a ROM like it would run through MAME, if I understand the information correctly. So in theory, you'd be able to extract the ROM from the disc. There's no real point since those have been dumped for years now but what about Hyper Street Fighter Alpha? It's only a versus mode that combines all the alpha games similar to Hyper Street Fighter II. Is there a way to dump that specific game and run through MAME or some other emulator? I'm going to assume the ROM is packed like the other arcade versions of the game but I have no way to verify this. Are there tools to explore a PS2 disc and it's contents? Or are there smarter people than me who can find this information out for the sake of preservation? 

The other reason I ask, is because Street Fighter Alpha Anthology doesnt seem to be compatible with the emulator I'm using at the moment and it's an unlockable game. I think it would be cool if could be a stand alone ROM that could be booted by whatever emulator can run it. I'm sure there are other games this could apply to as well.

I've seen this done with Nintendo Gamecube games like Animal Crossing and Ocarina of Time Master Quest, so I'm curious if this could apply to PS2 and Xbox.

This post has a link to imgburn that says that is how you do it

Actually disregard my post I see you are trying to do something much more complex

Yeah lol. I was reading the post and the outdated post it linked to thinking I was missing something. 

I have no clue how Capcom wraps their ROMs to be played on PS2, so I dont even know if it's possible to pull it off the disc. I'm going to assume either A) It's not possible because it's encrypted or, B) No one really ever thought about it because it's a pretty obscure thing to do.

I've seen people from Mugen forums open the ISO and rip sprite animations from that specific disc so It got me thinking if it was possible. Especially since ROMs were pulled directly off of Gamecube games. I've also ripped my game and tried to peek into the ISO but I dont think I have the tools to get more  than just surface level stuff. I'm also not well educated on this kind of process so I'm learning as I'm attempting to do it. Which makes it difficult to convey what I'm trying to do. 

Thanks for trying to help though!

why wouldn't you just play the games in PCSX2 by ripping the disc they are on into an iso

Two reasons.

One, the game has all sorts of graphical issues and slowdowns when emulated. I imagine that's due to how the game itself is structured since it's a compilation. I could never get it work properly on my old modded PS2 with HDLoader either and that was the explanation given back in the mid 2000's when the game came out.

Two, I kind of want a seamless launch experience for Bigbox. If the game itself actually ran properly, you'd then have to unlock it or enter in whatever code was necessary to access it since it's a hidden game. If the game was able to be ripped off of the disc similar to how we have the others (ssf2t.zip, sfa3.zip, sfiii3.zip, etc...) I could directly launch it, in theory. I guess it would depend on if the ROM is even playable in MAME since MAME doesnt have a listing for it or if you'd need to use some other emulator like FBA or a standalone CPS2 emulator. 

To a lesser extent, I'd like to this with Metal Gear 1 & 2 from the MGS3 Subsistence disc but there's less hoops to jump through to get to those when you launch the disc. So I just made two listings in Launchbox and had it launch the ISO instead of the MSX ROMs.

I think I may have found a solution that is way simpler for what I was originally trying to do.

So instead of ripping the ROM off of the PS2 disc itself, I created a save state right at the title screen for the game I wanted. With that said, is it possible to have launch box launch a PS2 iso with a PCSX2 save state? If so, what the command line I would use?

It is if the emulator supports loading save states via command line, Mame allows it and it does work through LB.

You would have to check the emulators documentation to see if it's possible.

I'm gonna have to do a little digging then. The last thing I was able to find so far was a post from 2010 that says an old version of PCSX2 could not load from a save state.
