Wait, is it not based on a decompilation of the game like with Ocarina of Time and Mario 64?
it is remake done with the XNA framework
No, how would that even work?
There's already an LADX decomp project, it's not unfeasable
Yeah I know, I've done a bit of work on it myself. It's not a decomp though, but a disassembly. The game was written in Game Boy assembly language, not C, so it can't be ported to other platforms, it has to be emulated.
