RESP1 artifacts in Missile Command #21

Closed thrust26 closed 7 years ago

thrust26 commented 7 years ago

At the bottom of the base P1 is displayed.

There is a RESP1 in this line. The first copy (there is only one) shouldn't show, but it does in the new core and Stellarator.

That's interesting --- I have checked missile command before, but failed to identify this as an artifact :smiley:. I am very curious what causes this. If there is a RESP1 in this line, then this must be the consequence of some badly handled overlap between RESP1, the draw counter decode and the write to NUSIZ.
