EMoney120 Posted January 30, 2007 Share Posted January 30, 2007 (edited) thats the problem, i don't know what file has the 1.50 EBOOT.PBP u download the 1.50 EBOOT seperate is there an easy way to find out if LCS is patched or not before i buy it. and i know i have to buy it used which is really hard considering none of the game stores have it used i really dont know. i have my old lcs case right here on my shelf but i dont think its any different than the patched lcs version box, since people have been saying the patched boxes have copyright 2005 on the back and were still patched.

I know pspu has a thing on it but I don't know where it is, if someone knows when the patched versions were released a simple browse through pspu's achive will yield the results in minutes. edit: found it: How to tell the difference between an unpatched, and patched version of LCS.

GTA3Freak-2001 Posted January 30, 2007 Share Posted January 30, 2007 well i heard downgrading past 2.5 on my moptherboard can brick my psp. but i kinda scared of taking the chance of downgrading. That normally is the case but this downgrader applies the patch which allows a motherboard of your type to successfully downgrade. Or so the readme for the downgrader says.

Yep, download the 3.03 Firmware onto your PC from here, http://www.psp-hacks.com/file/958 (don't worry about it being US, it doesn't matter) Then copy the EBOOT.PBP to your PSP here, ms0:/PSP/GAME/UPDATE (you will have to create the UPDATE folder)... On the PSP, go to the memory stick option and simply run the update... By the way, I've not heard any reports of the downgrader not working or bricking so if I were you I'd go for it...

edisoncarter Posted February 2, 2007 Share Posted February 2, 2007 I see what they did. Basically they renamed the exploit savefile from ULUS10041S0 to ULUS10041S8. GTA:LCS only saves/loads savefiles numbered 0-7, and the FW patch only goes into effect for savefiles 0-7. The trick is that GTA:LCS will find and load higher numbered savefiles during the autoload stage (it must be using ULUS10041S? or scanning 0-9), so by renaming the savefile to S8 they bypass the FW patch but it still can be loaded by autoload at the start of the game. Nice find by Noobz! So the GTA exploit lives on...

edisoncarter Posted February 2, 2007 Share Posted February 2, 2007 EC: Wow, they are smart! I would never of though of that! I think everyone assumed the patch was too simple to get wrong, which is why it took so long before anyone went to the work of looking at the patch code. I still can't think of why the patch would be written this way instead of more airtight ways that are simpler. The obvious way would be: if (strnicmp(pszDir, "ULUS10041S", 10) == 0 && ((short*)pData)[2] > limit) return (fail); To do it the way they did it, you'd have to do something more confusing like: if (stricmp(pszDir, "ULUS10041S0") >= 0 && stricmp(pszDir, "ULUS10041S7") <= 0 && ((unsigned short*)pData)[2] > limit) return (fail); or something like: if ((stricmp(pszDir, "ULUS10041S0") == 0 || stricmp(pszDir, "ULUS10041S1") == 0 || stricmp(pszDir, "ULUS10041S2") == 0 || stricmp(pszDir, "ULUS10041S3") == 0 || stricmp(pszDir, "ULUS10041S4") == 0 || stricmp(pszDir, "ULUS10041S5") == 0 || stricmp(pszDir, "ULUS10041S6") == 0 || stricmp(pszDir, "ULUS10041S7") == 0) && ((unsigned short*)pData)[2] > limit) return (fail); Link to comment https://gtaforums.com/topic/266053-any-downgrades-for-281-yet/page/2/#findComment-4037148 Share on other sites More sharing options...
