Hacking AKAIO, rumble in homebrew, per-game settings.

[Vague Rant]

I was just fooling around with Spinal's DiagnoSe and the rumble tester contained within, and found that it's a bit of a struggle to get it to do what I'd like. At the moment I have rumble off by default, because for the most part I don't want it; it's annoying and lame. What's rumble doing in Picross, anyway? Regardless, because homebrew has no per-game settings, I have to enable rumble globally to use it in DiagnoSe or any other homebrews which use it. I'm aware that I could choose to enable it globally and run through all my rumble-enabled games and specifically turn rumble off, but this isn't really something I want to have to do, so I was curious as to whether there is something I'm missing; another way to go about this. If there isn't, I'll happily ignore it, because occasions where I need to test my rumble or use it in any other homebrew (what even uses it besides Lameboy?) are few and far between.
