Have you ever looked at the pycho kiss fps engine on dreamcast it look's as modable as most. It's based on the Lithtech 1.5
engine..
Game's that ran on that engine are
1.0
Shogo: Mobile Armor Division by Monolith Productions (1998)
Blood II: The Chosen by Monolith Productions (1998)
1.5
KISS: Psycho Circus: The Nightmare Child by Third Law Interactive (2000)
Might and Magic IX by New World Computing (2002)

For Half life dc
I could try to help with the dll's i downloaded all of them a wince version of the src. it should be possable to compile them as a sh4 target.\
No promise on this.. I dont have wince Dev kit set up right now, i have been doing kos..
I would like to see a mod for half life , that look's like quake 2
since quake 2 is a no go to fully port to dreamcast.. I'm sure something could be made to look like quake2 on half life dreamcast engine..
MY 2 cent's lol
