I still get the rainbow screen when I boot my pi so it's not getting enough power.

Rainbow on the whole screen on boot? This is normal and is just telling you the GPU has booted up successfully. If you are getting low voltage you would see a lightning bolt symbol in the upper left corner of your screen. If your power strip is good quality I dont suspect youll have any voltage issues.

"a lot happening on screen" is subjective.

I was fighting three medium sized ships with a lot of missiles while all three were giving me "bullet hell". That's when the tempo on everything dropped substantially.

What colour box did you get ?

I've never gotten a box. That's why I was asking about them. I guess I've never really abused my pi yet.

@obsidianspider said in SNES Bio-Metal slow-down (throttling?):

@Lyle_JP SNES shooters were notorious for slowdown.

As far as the Pi telling you when it's overheating, it's on by default. You have to explicitly turn that off.

Both good things to know. For what it's worth, I haven't been able to duplicate the exact conditions that caused the profound slowdown. But I still see minor slowing here and there in the game. I'll chalk it up to "typical Mode 7 SNES shooter" issues and not worry about it.

Thanks for everyone's input.
