This is my first ever publically released lua application!
A souped up "Hello World!" with a button tester built in, which displays which key is pressed, but due to the RESTART and SCREENSHOT functionality built in, it does NOT test the buttons START and SELECT.
Home, Volume, Screen and Note buttons are also excluded.
If this crashes your PSP just remove the "System.usbDiskModeActiva te()" line fromm the top on the index.lua file.
I don't care if you use the index.lua file, it's there to learn from!
Place the "Hello World!" directory in:
"ms0:/PSP/GAME/luaplayer/Applications" for 1.00 and 1.50
"ms0:/PSP/GAME150/luaplayer/Applications" for 2.71 SE
Expect more from me in the NEAR FUTURE!
