For one byte of RAM, I'll give you another 2 cycles:
LDX ScanNumber ; 3 Next line: tiles or ball?
BNE BgLine2 ; 2
; BIT $00 ; 3
LDX readgrantedzerofromram ;-)
JMP NormalLine2 ; 3 13
BgLine2
; NOP ; 2+1
JMP X3 ; 3 13 76
-----
NormalLine
LDX #0 ; 2
NormalLine2
STX COLUP0 ; 3
STX COLUP1 ; 3 8
STX ENABL ; 3
Greetings,
Manuel
