I'ver tried the PC version and must say: It really rocks!
Especially your custom engine lets it look like new game.
The maps are looking like the old Blood but they are sooo much nicer!
But I dont think that the maps of the PC version will work well on DC. If yes, the loading time will take minutes. On my WINME System with 256 ram and 1800XP Processor the loading time is high. And when you compare it with DC's 16mb ram and 12x GD-Drive, you will agree that the maps have to become extremely smaller.
I think that it's possible to make it run on the homebrew ports but not on the TS port. Reaper told me that he'll bring out a new version of his RADQuake port which has 14mb of heap and stereo sound so I think TransfusionDC seems very realistic!
scrambled or unscrambled stuff (confusing)
When you compile your DC source you'll get an ELF file. This ELF file will be converted to an unscrambled BIN file. To make the DC think the BIN is loaded from a GD and not from a CD you have to scramble it. Or you use DCHakker or Demomenu, they let you load an unscrambled BIN after presing the Y Button.
There's a tool that can tell you if a BIN is scrambled or not:
