You need to use a cheat with something like Codebreaker (which is not compatible with nonBC PS3s/blacklisted ELF by Sony) to patch the memory to create a flag that went unused on the NTSC-U version of the game, also the installation is buggy because it was built for japanese versions of the game.
There is an alternate way to do that by patching the ELF executable of the game but it's really complicated.
The Final Mix version of the game though allows you nativelly to install if it detects a HDD plugged on your PS2 (PS3 in this case). I have to do that since ages though (atleast 2,5 years), I may be a bit off on some tiny details.

EDIT: Don't do your tests with games like SOCOM that just CACHE the files on the partition because once you exit the map or the game the files are going to get killed from the cache leaving an empty/nearly empty partition. The best option you could go with is in my opinion Resident Evil Outbreak 1 and Kingdom Hearts Final Mix+ that STORE a the whole map/model/audio/script information on the HDD in a simmilar way current generation games/consoles work.

There's plaintext lists of a bunch of PS2 title ids in all the ps2_emu files if you unself them There's some flags too at the end of the lists:

-mbrboot....-invalbnnetcnf..-poweroff...-booterror..-installerror

I just had an idea... back in a bit.

Dammit we finally get back on the PS2 side and my PS3 broke...FML.
Suggestion: Anyone know of any PS2 devs? If we can get one to make a hombrew that acts similarly to the games that do full game install then maybe we can get ps2 games running off hdd. Or we can mod a game so that instead of installing itself actually installs a different game.

Just some of my thoughts.

I supposed, but i had my doubts if there was something inside the data package specific for each game, but at this point i guess is not

The data package is "dumb" and does what the emulator orders (the most "clever" thing it does is that has two different installations for the main disc and the patches), good because theorically by tweaking the emulator this functions can be used by other games (adding a new DISC_ID in a interesting position replacing other DISC_ID from a similar game with similar requeriments)

The problem is that it's different type of data, the game won't boot since there is no executable for it. The idea of what you said is to find the (debug) syscalls that are responsible booting/linking an ISO 9660 file off dev_hdd0 which is the only function PS2 Classics (PSAR disc image enclosed) still use regardless hardware revision.

EDIT: Also all PS3s but mostly nonBC PS3's have somekind of whitelist of what you can boot, there are specific funtions that are disabled to get used, hence most homebrew on PS3 result into PSOD (blacklisted elf).

LOL imma be stubborn and think it is still possible. At a friends house right now and fell asleep, woke up and no one is in the house....im scared lol. Also since the installation of the ps2 game only requires well.... a ps2 game I figure a Ps2 dev can eventually make a ps3 exploit on the ps2 side, or go the extra distance to make a homebrew game that does what I mentioned from scratch. Since iirc we know pretty much there is to know about ps2.

Yes, but the functions for the HDD are not "open source/documented" and the ones that were written from scratch in the PS2 homebrew scene are not working on PS3 hence you can't install a game on PS3's internall HDD using apps like OPL, that's what I'm trying to say. Last time I talked about it they said that they tried to fix that on PS3 but it seems that the emulator refuses to allow them to use those functions they created from scratch and somebody must do it with the official SDK in order for them to work.

OK thanks will look further into it when I get home tomorrow. And I'll buy water blocks for for my PS3 probably next week. And then a flasher. Hope my PS3 don't break again , its like my baby lol.

What I was thinking was to hex-edit the title ids in the ps2_emu.elf files (and ps2_gxemu.elf, ps2_softemu.elf) from a game that installs to HDD (and boots without the disc? Do any of those exist? I'm thinking Playonline but I don't know it's title id) to another title id (say SCUS_974.02 Killzone) then re-self them and put them back in dev_flash. Pop in the Killzone disc and see if it installs to HDD and is bootable from XMB. Unfortunately, I'm dog-tired and have to work tomorrow, but I'll pursue this later. Only problems I can see if this does in fact work are 1) I don't know if there actually is any PS2 discs you can install and run from HDD without the disc inserted, although Playonline seems to be one, and 2) that's a lot of work to install a single game, you'd have to edit the files for every game you wanted to install. However: if this does work, you could then take the installed folder and make a pkg of it. A few people could in a short time make pkg installs of most of the PS2 library.

Okay, I just changed my mind, I'ma try it. (I can sleep when I'm dead) I believe the Playonline title id is SCUS97269, and guess what? It's in the elf. I'm going to edit it to SCUS97472 (Shadow of the Colossus) in all the ps2 elfs (including the pst ones for Cobra) then re-self it and see if it installs the disc. Wish me luck.
