Uh huh.
He didn't write those emulators. He ported them. I know more then a few of the original authors tend to ignore the fact that he's essentially selling their work, and when pressed on that matter they tend to get a bit irked about it.
Bannister's work might ultimately make up to 2-5% of the total time invested in any one of those projects. And yet he's the guy making money off them indirectly through a clever loophole. The original authors don't get anything from his income.
How is that fair? If I wrote an emulator and open sourced it, I'd expect it to stay open source. Bannister doesn't even post the source for his changes. And he charges for Emulator Enhancer, and advertises himself in the emulator disk images. Give me a break.
