Congrats! Do you have a way for bullets to get destroyed when they go off-screen yet? I can't wait to see screenshots.
Oh, thanks for reminding me 
I needed to fix the (bug?) thing where when bullets go to the right of the screen (or left) then they continue on the opposite side of the screen in the same direction.
The z80 makes it easy because of that 3 bytes extra buffer it gives you

Three bytes extra buffer space? O_O Did I miss that somewhere? And I'm interested to hear that the Nspire does the same wraparound as the z80, even though I assumed that it would.

Sprite:
I thought the z80 had a crazy lcd layout... Like the last byte of visible screen data is followed by 3 more bytes... I'll check wikiti real quick
Oh, in a sense, but the standard fastcopy routines hide that from the programmer so that a 768-byte buffer will suffice.
Here's the code from that plane sprite, by the way:
