Open ASM_INTS.bas and follow the instructions

Code:
' --- IF any of these three lines cause an error ?? Simply Comment them out to fix the problem ----
wsave1 var byte $A0 SYSTEM ' location for W if in bank1
wsave2 var byte $120 SYSTEM ' location for W if in bank2
wsave3 var byte $1A0 SYSTEM ' location for W if in bank3
(also, there might be a newer elapsed.bas that uses DT_INTS. Does anyone know where that is?)
