Loading UMD's on 1.5 which needs 2.00 and higher

Post by EdwardFMA »

I think there is a easy fix for this please tell me if anyone has tried this already....

Technically wouldn't you just have to Unassign Flash0 and Flash1 the assign them to a folder on the Memory Stick which would contain a higher version of Firmware like 2.50. For example:

Code: Select all

sceIoUnassign("flash0:");
sceIoUnassign("flash1:");

sceIoAssign("flash0:", "msstor0p1:/" , "fatms0:/flash0/", NULL, 0);
sceIoAssign("flash1:", "msstor0p1:/" , "fatms0:/flash1/", NULL, 0);

sceKernelLoadExec("disc0:/PSP_GAME/SYSDIR/BOOT.BIN",0);
Technically i have more code so that if you don't have a UMD in it will ask for it and display it, but that is at home and i'm at school... Please Reply with your ideas on if this will work or not. ^^

I may be completly off, but the PSP doesn't reload all the PRX's before starting a game, does it? So the 1.5 PRX's would still be loaded, and it would attempt to use those.

exactly 1.50 prx would be still already loaded so you need to find a way to unload them and then load the 2.00 one ... like has been done by Aenea already.

actually the sceLoadExec call _does_ unload all prxes, execute the ipl, and reboot from scratch before executing the game eboot. the "only" thing that needs to be done is to patch it so a different firmware will be booted.

I think I'm going to lock this... this... well, lets just call it idle speculation.
