VBA's emulation of the Super Gameboy is very primitive. A simplistic high level emulation of certain 'command packets' sent from the emulated GB to the emulated SNES is employed, which gives somewhat-working borders, palettes, and extra controllers. Over a third of the command packets are not implemented at all. This isn't just about Space Invaders; many games use the extra sound and oam functions, and some use the functions that VBA does emulate in ways that it does not support. Timings are likely junk as well. In short, what I want to say is that VBA's SGB makes Mupen look like Nintendulator. I think VBA should be obsoleted for the specific purpose of making SGB movies. I don't particularly care whether there are viable replacements; an emulator that entirely ignores the existence of half of the hardware in the console is not accurate enough to do any justice to tool assisted runs. Thoughts?

Bizhawk will be the newer choice for SGB. I prefer doing a run of KOF '95 or even a playaround of Bomberman GB using Bizhawk.

Didn't bsnes contain a functional SGB emulator? I don't know whether it was implemented in other emulators, though.

we could also use lsnes. Just use a SGB enhanced game with the SGB loader.
