According to the docs, it is possible to burn dlf files to the rvt h. Don't know anything beyond that. Haven't tried it myself.
Do you know how one would convert it to a .rpf file? You would have to convert the whole game, not just the .dol file, right?
Normally you would use rdpack to pack the .dlf and the data in the $DVDROOT into a .rpf file. I wouldn't have a clue what to do for retail converted games. Maybe set $DVDROOT to a folder that contains all of the game data? I would be very surprised if any of this worked on a retail game.
Wait, If you set the $DVDROOT, it shouldn't affect the rvt-h because I thought it was used just for the NDEV, I could be wrong though, I'm no computer expert.
$DVDROOT does not affect the RTV-H. It is used by the NDEV and some of the disc mastering tools such as rdpack. rdpack takes the data from the $DVDROOT and the .dlf file and packages them into a .rpf file which you then transfer to the RVT-H using the rvtwriter software. It is basically the same as making a .rvm file except it is not padded to 4.7GB, therefore it is much quicker to transfer to the RVT-H internal hard drive.
rdpack is part of the Wii Mastering Tools. It was shared with an old SDK, I believe you can find them in this thread. http://assemblergames.com/l/threads/gc-and-various-other-sdks-development-docs.45368/
Sorry, I didn't notice that some more up to date documentation had been shared with the 3.3 SDK. It appears that they now suggest only using .rvm files with the RVT-H console. There are also step by step guides for updating the firmware and using Cygwin, would have saved me some time if I had spotted these earlier
I was looking through the file that you provided, and I couldn't find Cygwin anywhere on it, am I just missing something?
