- Colours are incorrect
Notes:
- BS-BASIC v1.0 have a graphic bug with the RX-78 logo, it doesn't set the read bank so all of the color
info minus plane 1 is lost when the screen scrolls vertically. Almost certainly a btanb.
- BS-BASIC v1.0 notes:
-- COLOR x doesn't do anything. It sets a memory location with x, but does nothing with it.
-- COLOR x,y where y sets the background colour. This part works.
-- When BASIC is first started, it sets the colours but doesn't save the information. So when
COLOR x is entered, although x has no effect, it also sets the background colour, which not
having been set, sets the background black.
-- At the first scroll, the display memory is disrupted in the logo area, probably another
btanb. After that, scrolling works correctly.
-- Need a real machine to confirm these problems, but if true, one can only wonder how such
obvious issues made it out the door.
