This routine prints the following tokens, depending on the galaxy number: * Token 220 ("WAS LAST SEEN AT {single cap}REESDICE") in galaxy 0 * Token 221 ("IS BELIEVED TO HAVE JUMPED TO THIS GALAXY") in galaxy 1 This is used when printing extended token 10 as part of the mission 1 briefing, which looks like this when printed: It went missing from our ship yard on Xeer five months ago and {mission 1 location hint} where {mission 1 location hint} is replaced by one of the names above.
.MT28 LDA #220 \ Set A = galaxy number in GCNT + 220, which is in the CLC \ range 220-221, as this is only called in galaxies 0 ADC GCNT \ and 1 BNE DETOK \ Jump to DETOK to print extended token 220-221, \ returning from the subroutine using a tail call (this \ BNE is effectively a JMP as A is never zero)
