    Perhaps on a related topic: Modifying and flashing a modified DVRP firmware is possible, but there seems to be an initial program loader on the DVRP which runs some check on the firmware and refuses to boot it, if (probably) the hash of some part of it does not match some value stored at an unknown location. (The purpose was to be able to replace a broken HDD with a generic such.) So when a modified firmware is booted, the PSX DVR will just hang with no possibility to write a new firmware but to program the flash chip directly to restore the original one.

    Interesting!

    That might be useful for what @krHACKen (Edit: Alright, it is... ^^) is currently testing in relation to the PSX! :)

    Little tip for those who are interesting in kelftool: to forge PS2KEYS.dat, You can retrieve all from ps3dev wiki. Just hash them and compare to author naming convention to put proper one in proper place.
