Yes that's right guitar hero for your calc.
btw those things that happen when you score are lightning bolts.Yeah I suck at sprite making.
Right now I'm adding different difficulty levels and fixing the hud.

nice so far, are you gonna have different speeds?

GIMME!
I WANNA TEST!
=D

glad you use the F1-F5 keys

Well, first try... I hit the ON key to stop it since my window wasn't set right. Causing a RAM clear. (no worries there though)
Second, still didn't have the right window.
Third, everything was fine. But... all I know is that my score is OVER 100, but not how much since there wasn't any room for a 3rd digit. =P

Overall, impressive. Weird timing though.

I wonder...

I remember in xLIB xLIB Revolution and SMSD that the timing was a bit off, so waht I did is that in the options I allowed the user to change hit detection to before the arrow reach the top of the screen instead of after it did. Since my game only had one single timing check (arrow had to match, else you missed, there were no boo, good, great, perfect, etc) some people were used to hit the key right before it scrolls up again, and some others pressed it either at the same time. That made things easier for everyone. Keep in mind XXR used the BASIC getkey though. SMSD used the xLIB one so SMSD detection was a lil different

ooh I see

I was actually, just for fun, coding more onto this at school.
Only really ended up with changing the difficulty, randomly generating 'songs', changing the 'hit' sprite, and showing a hit/total notes at the end.

The more impressive part, to me, is that I was able to understand how it all worked. (after awhile)

In any case, I look forward to see what you've got done. =D
