I opened my copy of gradius collection yesterday!
Ive only played the first 2 on it,
gradius 1 is same as if u ever DLed the rom, very old but good.
but gradius 2 is where it gets real good.
there are 4 viewing options for screen size,
and u can save your game which is interesting.
there's also a gallery mode w/ movies and music.
all in all, it's a great game to play on the go in short bursts.
regarding both games tho; using the dpad would be a bitch.
my dpad is modded so the games moves flawlessly.
but maneuvering tight spaces in gradius,
or pulling off moves in sfa3 with an unmodded dpad
will most likely frustrate you and get u killed
