Feature Request: Add frame blend option from GB core

[KremlingKuthroat19]

The Super Game Boy is my preferred way to play SNES games, especially with the recent addition of save states to the core. The only feature that it's missing from the Game Boy core afaik is the the frame blend option. Not many games use it but it's an effect that adds a psuedo-transparency. These two games I know use it, and there are probably more:

• Chikyuu Kaihou Gun ZAS
• Wave Race

Is it possible to add the frame blend option to the Super Game Boy?

I was looking up who did the frameblend and it is none other than paulb-nl himself!
