from retrobits:

I really wanted to play Laserix 2 again on my 5.00 M33 slim -- Its one
of my favorite homebrew games ever on the PSP. So I did a quick port
of Laserix 2 to PGE (Pheonix Game Engine) the past few days. Since
the game was implemented originally in Lua, this was not too
difficult. It should run fine on all custom firmwares, greater than
3.xx phat or slim. PGE is really a great game development platform.
I am very impressed with its performance
