.MT27 LDA #217 \ Set A = 217, so when we fall through into MT28, the \ 217 gets added to the current galaxy number, so the \ extended token that is printed is 217-219 (as this is \ only called in galaxies 0 through 2) EQUB &2C \ Skip the next instruction by turning it into \ &2C &A9 &DC, or BIT &DCA9, which does nothing apart \ from affect the flags
