no >.>  I actually haven't set up the stuff to make it.  I deleted a few parts of the example code, so I could use some other music, however I must have deleted something important, I'll resend it and try to fix it some

If anyone wants some more epic music, here are some more demos.  They really push the player to its limits though.  You can erase the first data structure in the example file, recall this into the code, and store it to Str4 to use the 4 button to test these.

The first one is from Pokemon Gold/Silver the surfing theme
The second one is from Big Blue in the original F-Zero.

Yes, you can have sound effects as well.  There are many options.

One way is to include it separate from the interrupts.  To play the sound effect you would just write the routine using whatever combinations of freq() you need, and then use that when you need it in the code.  The routine doesn't have to have interrupts disabled when playing the sound effect as long as you don't mind having your sound be interrupted by the music which may or may not be desirable.

Another way would be to modify the interrupt routine so that it queues all the sounds that need to be played every time one is loaded.  That would prevent simultaneous playing however.

Uploaded one more, this one is from .hack, never played the game, but it sounds cool and it shows how the tempo can be changed.

EDIT: By the way, you can change the interrupt frequency to speed up the music.  4 is slightly faster, 2 sounds nice but its really sped up, 0 is just insane.

The way I have it set up now you load songs into the music player using the L variable.  However, the routine also uses the P variable to figure out what to play after the sound has finished.  If its the same song as before, that's how it creates a loop.  If it is zero however, it will be loading the stop command into the player which will halt all sound once the original track has finished.  You can even do more exotic things with it.  Lets say you have some music which has an intro part and a loop part.  You can load the intro part into L to get it going and then load the loop section into P so that it will continually call the loop section after the music reaches the end.  Its a pretty cool system.

great! i like this sound =)
when in a game z80 with good music background?
I am impatient

* calcdude really wants that adapter
I'll say "keep up the good work!" even though I'm not judging it myself

Did I just... get rick roll'D?

Regardless awesome stuff lol
