s_king Wrote:My application is checking the first 4 bytes of the selected file and allows you to use if it's:
~PSP in the header prx
_ELF in the data prx
So you can't use a compressed prx as data and/or a decompressed prx as header.

Adding the 'patch 0xE7E8 part in the vshmain.prx' ability to my program is really easy. But is this necessary only in vshmain or every other prx?

Edit: 0x18 - 0x1A is the module identifyer part in the decompressed prx?

compressed prx 0x30 = elf 0x18
compressed prx 0x34 = elf 0x40
compressed prx 0x54 = elf 0x48

compressed prx 0x48 = elf 0x5C « only vsh modules
compressed prx 0x58 = elf 0x68 « only vsh modules

edit:
regarding your vshmain.prx patch question. only vshmain.prx...
by the way its interesting to see how many prx's M33 are physically patching. DAX did it as far as I know completly by patching the memory
