Help Needed: Unusual PSP BIN Header

Are you possibly referencing "Inside" or "PSPLink" ? I'm pretty sure I have both but I haven't tried to set them up. I could try on my DC release machine though

Info dump for anyone working on it.

Code:

0x08960A0F file loaded to
0x09FFF2B3 directory folder is loaded to



08836C00 is the file reading function
088051E8 is too late, config messed up

Looking for checkfunction 
08804E50 calls where we eventually hit 088051E8
088AAD0C big switch stuff, seems important

088103B0 = String Comparison: addiu    sp,sp,-0x10
088AA9CC also seemsto be important

z_un_088aa9cc: VERY IMPORTANT TOO. CHECKS THE STRINGS
    andi    v0,a0,0x3
   
088AAD0C = Check Line: z_un_088aad0c:    sltiu    v0,a2,0x4



088051D4 got to here then got distracted with other stuff

 

Hi, I decrypted the EBOOT.BIN, as suspected, it is a regular user prx. (I PMed the link to the decrypted prx to the OP)

The ELF is somewhat interesting because it has symbols for undocumented nids, other than that the path to the TITLE ID it checks the config for is parsed from PRODUCTCODE.TXT sadly I would have to disassemble the binary to see what the expected configuration is, which I currently have no time to do, at first glance the application appears to be downloading videos and playing those using the psmf.prx module, I would assume the configuration contains the link/path to the videos.
