Yeah, good thing you mentioned the Dreamcast's small amount of RAM, as crafti was taking a little over 16 Mb of RAM and some of the graphics were corrupted.
I actually had to remove some of the text overlays due to RAM issues. (it's also the reason why it only has sound effects and no music)
Many thanks to @Vogtinator
for the game, releasing its source code, as well as his fantasic programming skills.
Because believe me, you're a refreshing change compared to some proprietary devs... (see postal's source code as an example)
It's the reason why the GCW0 and DC ports are even possible. (porting Minetest to both consoles was out of question)
Hopefully i can find the motivation to clean up the sauce so i can get it merged upstream.
