Tromedlov has released a new Lua App in our PSP Emulation & Homebrew forum, heres what the coder says:
This is my first homebrew program that I made from combining some of the sample programs from the Lua player. This program initializes USB mode while your in the Lua "Lowser", so you can edit and compile your programs on the spot. You can already do this with the "3d cube" sample program, but I made a program specifically for this purpose. It also has moving stars in the background, and a zoom in text (I did that on my own). I can't wait to start homebrewing some of my own stuff, this is awesome!!!
