I've made a hdma effect that writes a sine-adjusted scroll value to BG2HOFS. It works fine, but the window edges also become twisted, in both mednafen and bsnes-plus. Is this an emulator bug, or is window supposed to be affected?

Grog's guide explicitly says window is not affected by scroll, but then with the state of SNES docs and conflicting info around...

Oh, it only looked that way, because the outside-area was zeroed, showing the bg color. Both emus working fine.
