Deniska the winner of the first PSP News 30 Day Coding Competition has ported the awesome Rise of the Triad to the PSP, heres what he posted
"Attached zip file contains the first version of my port of
Famous Doom-like FPS from Apogee/3D Realsm: Rise Of The Triad (http://www.3drealms.com/rott/).
It's still in a very early stage and crushes after ~30 seconds.
But it's a proof of concept.
I just want to release a first version before someone checks the code in to some public repository and accuses me of stealing it as it happaned with rRootage port, which I stoppped developing and left in capable hands of mrBrown...
Current demo features
-full screen support
-sound
-full speed emulation
I'll try to release a playable version short after I get back from my ski vacation."
