Ms. Pac-Man Maze Madness no music audio when entering the first portal of the first level.

When entering the first portal of the first level the music cuts out and stops playing. Not supposed to happen. Running the NTSC version of the game. Confirmed clean dump, tested in bin/cue format and chd format.

Known issue. You can pause and resume the game to work around it.

Oh ok will test that thanks.

I found that many games are GD_PAUSE with SPI_CD_PLAY command. It works fine if I change the code like this.

gdromv3.cpp

void libCore_CDDA_Sector(s16* sector)
{
    //silence ! :p
    if (cdda.status == cdda_t::Playing)
    {
                SecNumber.Status = GD_PLAY;
                libGDR_ReadSector((u8*)sector,cdda.CurrAddr.FAD,1,2352);

case SPI_CD_PLAY:
        {
            ...
                        cdda.status = cdda_t::Playing;
                       //SecNumber.Status = GD_PLAY;
                       SecNumber.Status = GD_PAUSE;

Unfortunately, the above code seems to be incorrect as a bug was found in some games (Bust-A-Move 4).

It does fix Ms. Pac-Man though, so that's a good hint at what the problem could be.

I checked on real hardware and Status=GD_PLAY is set immediately when a CD_PLAY command is issued. So it's probably not the right fix.
