; the y lookup tables encodes this formula: BITMAP_ADDRESS + 320*(py>>3) + (py & 7) (y from 0..199)
; We use the 64tass syntax for range expressions to calculate this table on assembly time.

`Additional custom compilation targets (such as VIC-20) <https://github.com/gillham/prog8targets>`_
Various custom targets for Prog8 that are not (yet?) part of the Prog8 examples themselves.
These additional compilation targets may be in varying state of completeness.
Perhaps most recognisable at the time of adding this link, are the various VIC-20 targets.
