Acoustik Posted February 16, 2006 Share Posted February 16, 2006 I Repost ... ---------------------------------------------------------------------------------------------------------------------- ... One man ( a french ) succed to run GTA LCS on as Firmware 1.5 ... His Technics ... Yoshihiro finally chose to share his method on how to create a loader to run gta:lcs on 1.50 psps, here it is: decrypt all your ~psp and rebuild your iso download the pspsdk and build your ~PSP decryptor with the 2.0 PRX and ELF support you have all you need on psardumper 2a i not have time for that assuming it will with DEVHOOK 0.22 because dev hook not use the game_pluging.prx for load your iso and iso emulator yes . look when you load your iso from the psp os with umd emulator your psp after the white screen check if your eboot.bin is encrypted and if is not encrypted you get an error 8002048 :=) . now download the pspdev sdk and code your loader ;=) (this is a log from sonyxteam channel) As he said we do not have time for that, so I suggest another dev team work on this, based on yoshihiro's method. The Link$ -> http://www.sonyxteam.com/modules.php?name=...=article&sid=22 Good luck for the which that code the loader... Sorry for my english i'm french !!! ------------------------------------------------------------------------------------------------------------------------- And I add the of the misc. necessary programs : - PSPSDK - Psardumper 2a - HookBoot Launcher (Devhook) V0.22 - http://ps2dev.ps2-scene.org/ In The First News : 04 Oct 2005 PSP memlmd... Very interesting things are happening in PSP scene. Great work Nem and PspPet With the release of IPL decrypt stuff and PSAR decrypter 2, I've decided to put on the site the source of memlmd.c. That is the decrypt code from 1.0 fw; memlmd has only 2 keys; you can find keys 0x2->0xF in mesg_led. Also, I compiled a table of calls to semaphore , a (WIP) sample to decrypt PSP files: PSPdecrypt and COP0 Control Registers usage. The Author Speak of IPL... IPL Of GTA ?? I Don't Know ! - http://forums.ps2dev.org/viewtopic.php?t=931&start=30 A Similar operation with another game... It's all I know... Good Luck...

GTA3Freak-2001 Posted February 16, 2006 Share Posted February 16, 2006 Its not actually the LCS disc working on a 1.5 PSP but rather an iso combined with a myriad of decrypting tools and loaders which bring this technique almost into warez and illegal territory.

Rob. Posted February 17, 2006 Share Posted February 17, 2006 That is the decrypt code from 1.0 fw; memlmd has only 2 keys; you can find keys 0x2->0xF in mesg_led. Also, I compiled a table of calls to semaphore , a (WIP) sample to decrypt PSP files: PSPdecrypt and COP0 Control Registers usage. GTAFreak is correct, being able to decrypt te files in order to make it run on a lower system, could easily mean that you wouldn't need a disc for long, and so i think you'd just be able to rip games like LCS to a memory stick. For all i'm still aware LCS will NOT run on anything lower that 2.0, is this still the case? Link to comment Share on other sites More sharing options...
Cubanwhip Posted February 19, 2006 Share Posted February 19, 2006 Yeah. LCS can only run on 2.0. Ripping it onto a memory card is the only way to play it on anything lower, and doing that is illegal. So really, Acoustik should not be posting that because those are instructions on how to rip the game onto your memory. Link to comment Share on other sites More sharing options...

.Christopher. Posted February 19, 2006 Share Posted February 19, 2006 does it really work! Link to comment Share on other sites More sharing options...
Cubanwhip Posted February 19, 2006 Share Posted February 19, 2006 Oh. So it's legal. Well, sorry for the mistake. Anyway, I can't really understand how to make LCS run on 1.5. It all looks so complicated. Well, if anyone knows how and can simplify it, please PM me. Link to comment Share on other sites More sharing options...

But as far as these forums goes its not allowed as there's no way to dertermine if someone really does own the orginal, so in principle its fine but not really to be discussed here.

~Neon~ Posted February 23, 2006 Share Posted February 23, 2006 Wow, this is great news. Im going to test it out. Hopefully this now means we can extract the ISO and mod it as if it was a PC GTA. Link to comment Share on other sites More sharing options...
