Speaking of - great work on those covers, Shenske! This is one of my favorite cover sets. And I blame you for getting me into those *ahem* questionable entries.

I hope you'll someday tackle the stranger hacks like Perla, Quartz, DarkCry, and ChaosBlack. (If you do ChaosBlack, I'd suggest something like Mewtwo for the cover, rather than...Chaos...from Sonic...

)
I've also heard there are Brown, Jade and (Creepy)Black carts for GB/C/A out there, but I've never found them.
