I don’t quite understand that, since the program reads from the file, not the drive itself. One can easily make a copy of the file (and if one is advanced enough to go about messing with firmware then it is assumed that one is smart enough to be able to create a copy).[/QUOTE]
This is just a matter of the effort to be invested. I took the simple version, just allowing read speed and RPC patches on partly compressed firmwares. This is safe and what most users need.
Modifying BD media codes has a too high risk of bad burns, modifying DVD media codes does not make much sense anymore. Recompressing such changes has a high risk of killing the drive.
I could spend some time on a mode that displays the media code, does not allow media code changes and still allows to apply read speed and RCP patches, but this was just wasted time.
