Exact same as the PC in almost every aspect with the original but heavy optimized to allow running it on the Dreamcast.
This is a very rought test and playtrought for the mentioned game and altought some problems due the 16bit palette and an engine that doesnt release the ram, it goes pretty well.
I forgot to save in the vmu so all the advance is lost, but anyway is just a video to show it running it with a gdemu and the most up to date Dreambor from Ian.
