NIGaShootuh is a fun space shoot em up. If you have a OE/M33/SE firmware then copy the “NIGaShootuh BETA 2” folder to the GAME150 directory inside of PSP on the root of your memory stick. If you have 1.50 then you will have to kxploit the eboot and copy it to the game folder. if you are on any other homebrew able firmware then put it in the GAME folder.

Changes:

-added menu system
-overclocked cpu to 333
-now enemy shoots back at you
-fixed all collision, so now collision is a lot better
-added semi-homing missiles
-added a points system
-added ability to pause your current game and return to the main menu and when you go back to the game it will be in the exact position as when you left.
-fixed various bugs
