Today I was experimenting with HMMC , with the R#25 CMD bit set to 1, and openMSX didn’t behave as my turboR did:

* In TEXT2 mode, the command did not execute at all, CE remained false.
  
    10 SCREEN 0 : WIDTH 80 : PRINT : I=65
    20 VDP(26)=VDP(26) OR 64
    30 VDP(37)=0 : VDP(38)=0 : VDP(39)=0 : VDP(40)=0
    40 VDP(41)=16 : VDP(42)=0 : VDP(43)=1 : VDP(44)=0
    50 VDP(45)=I : I=I+1
    60 VDP(46)=0 : VDP(47)=&HF0
    70 IF VDP(-2) AND 1 THEN VDP(45)=I : I=I+1 : GOTO 70
  
  Expected output: ABCDEFGHIJKLMNOP

* In GRAPHIC1 mode, the command executed, however the data did not appear on screen.
  
    10 SCREEN 1 : PRINT : I=65
    20 VDP(26)=VDP(26) OR 64
    30 VDP(37)=0 : VDP(38)=0 : VDP(39)=24 : VDP(40)=0
    40 VDP(41)=16 : VDP(42)=0 : VDP(43)=1 : VDP(44)=0
    50 VDP(45)=I : I=I+1
    60 VDP(46)=0 : VDP(47)=&HF0
    70 IF VDP(-2) AND 1 THEN VDP(45)=I : I=I+1 : GOTO 70
  
  Expected output: ABCDEFGHIJKLMNOP

Also the TEXT2 program only outputs anything when going to GRAPHIC1 before it (Basic: SCREEN 1). Otherwise, it will complete instantly and won’t output anything.
