Can Demoniak be ported over the PSP ? that would be super, there is a sdk for psp and from what i can see demoniak is a nice engine and it suports lua .. psp can run lua scripts , there is a lua player somewhere that i got and tested out. If you are interested in it or the psp sdk i will gladly help.
If it can be ported to the psp there will be a lot of homebrew enthusiasts out there dying to get their hands on such an engine .. there is allready a C++ engine for the psp "LTE 2" but it's quite hard to master .. your engine from what i can see is easy to understand.
