I see you didn't set bit4 of $FF06 (same as $D011 on C64):
LDA #$3B
STA $FF06
Two notes more:
- preserve the first two bits of $FF12 (due music possibly running, they're high bytes of one of the two channels)
LDA $FF12
AND #$03
ORA #$F0
STA $FF12
- keep it both PAL/NTSC compatible:
LDA $FF07
AND #$40 ; bit6 for PAL/NTSC
ORA #$18 ; bit4 for multicolor
STA $FF07
