Japan had to wait long enough for the first MSX game
to show up on the Virtual Console that anything extra D4 Enterprise (or Nintendo, or whoever makes the emulators for the VC) could do to make the experience a pleasant one is welcome. Aleste
features an extra "MSX Option Menu" that is accessed via the minus button, which allows players to choose between MSX hardware-based music and the more advanced FM music that, back when the MSX was real hardware
, required an add-on card.
Impressively, you can also swap the two fire buttons via the "Button Change" option. It's a good thing for Nintendo that they'll never bother to release this over here, because the four people who would download an MSX game would get spoiled.
