wont work, that file is probably a fw 1.5 dump
reasons it wont work
1) PSP filer is written for firmware 1.50 ONLY. It uses firmware 1.50 kernal mode, which means it wont work on any other firmware
2) Still need to write a 1.50 IPL to the...IPL. Apparantly that needs kernal mode (im no coder, so i dont know)and there is no kernal mode on 2.80...yet
