TODO:
- raster effect in Gemini Wing THE END ending, needs accurate clocks measured
on a genuine board (waitstates too?) and a side-by-side test;
Notes:
- btanb: missing drums in backfirt, there isn't any ADPCM / rom that makes
that to happen (code still tries to writes on that, but it's just nop'ed);
