DIY: You'll need UMDGEN. Extract BOOT.BIN from the iso; hex edit this file & go to 00000C94, write zeroes (replacing 03004014) then...
PSP/EMULATOR ONLY: Re-insert the file, relink EBOOT.BIN (use BOOT.BIN as source)
VITA (ex. Chovy Sign): I used the sign_np found within Chovy Sign's "tools" folder. Execute "sign_np -elf XXX YYY 9" where XXX = input, edited BOOT.BIN, & YYY = output signed EBOOT.BIN; then with UMDgen replace EBOOT.BIN (don't relink, leave BOOT.BIN untouched)
I would've given you another patch (the attached file follows the "PSP" method) but encryption is a big no-no (size, legalities).
