I've done everything it said in the readme file. Only thing that's stopping me is when I execute 3.52 M33CREATOR.

It says " loading 1.50 firmware...SHA1 of psar doesn't match expected"

I have the official 1.50 eboot.pbp(renamed 150.pbp as it said in the readme) and all the other stuff needed.

Just someone please tell me how I can fix this problem. please?

make sure its not called 150.pbp.pbp check in winrar if its called that and on your desktop all u should see is 150.

That's one of the problems though. When it's just named 150..it shows it is just a file and is not picked up by the M33 Creator. When it's 150.pbp .. it is shown as a pbp file and is picked up by the M33CREATOR

but the SHA1 problem then comes up..

I've tried downloading two different 1.5 eboots ..but they are the same file strangely.

Do you all know of any other websites besides pspupdates.qj.net and pspcrazy.com ? that i could download the 1.50 eboot from?

does anyone think it could be the memstick?

my memstick is a: SanDisk MemoryStick PRO DUO 256 MB

is that one that usually messes up?(i've emulated on it before if that count's for anything)
