I think the SLEEP macro uses undocumented opcodes in it's
default state. StellaX doesn't support these. There should
be a compiler switch that you can define to make the macro
compile to only normal opcodes instead.

Can you reproduce it reliably on the emulator? When I try
hitting SELECT in your game, the sound plays just fine in z26.
But while working on the next version of z26 I had some situations,
where it seemed as if there was an echo in the sound. Maybe
the sound buffers get played twice or something. I can't figure
out what triggers this, so it's a little difficult to find out
what's going wrong.

Is this what you are hearing, and do you have any idea how to
trigger this? That would help me to find the bug in z26 and to
fix it.
