I think it's hardcoded in this part of the code:

  if (sync == VDP_SYNC_AUTO) {
        vdp->palMask  = ~0;
        vdp->palValue = 0;
    }
    else if (sync == VDP_SYNC_50HZ) {
        vdp->palMask  = ~0x02;
        vdp->palValue = 0x02;
    }
    else if (sync == VDP_SYNC_60HZ) {
        vdp->palMask  = ~0x02;
        vdp->palValue = 0x00;
    }

Back in the day it could result in unwanted effects on a TV, but I doubt a lot of us still suffer from that

I have always thought that Konami had in mind to release Space Manbow internationally because all in-game texts are in English and the game is from 1989 (well, late 1989) and other Konami MSX from that year arrived to Europe (Nemesis 3 and Contra).

I meant the country of production

Yes, I know My comment was as a side note. All Space Manbow texts are in English, quite suspicious, isn't it? My guess is that Konami was planning to release it outside Japan but who knows.
