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; }
While the Japanese Space Manbow forces 60Hz, it's unofficual Dutch sequel Manbow 2 forces 50Hz.
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.
