Gambatte Sprites not rendering #1083

To Reproduce: Load Pokémon Red Wait for the Introduction animation battle to begin. Sprites glitch as attached.

This only appears to effect GameBoy games in Gambatte, not GBC Games. Tested against: https://github.com/TASVideos/BizHawk/commit/1f0c9f2be883ab1c9d5dc23589217cbd4248c29e

Hmmm, actually the sprites are fine, it's the background that isn't being displayed. I'll look into it.

It only appears to effect GB games playing in GBC mode.

Turns out Gambatte wasn't intially able to load GB games in GBC mode at all. This capability was a side effect of having BIOS support.

Honestly, I forgot I even did that.

So I've reverted the behaviour back to where GB games will not load in gambatte in GBC mode.
