What I mean by this is using multiple cartridges at a time. Let's say...
1. Converter cartridge to play NES games (Retro Freak)
2. Game Genie adapter (because it's easier to pull games out of)
3. Game Genie
4. NES game
That's 4 separate cartridges plugged in one on top of the other. Would that draw extra power or put extra strain on the electrical components of the Famicom or any console with a similar set up?
Those adapters wouldn't draw much power, mostly only exotic things like a flashcart, and those should still be fine.
Even if it would draw more power I don't think it would be bad for the hardware as long as it is less power than the components can handle which is most likely much more than what the AC-adapter can provide anyway.
I guess the only possibly bad thing might be mechanical strain if put a lot of heavy things that bends some pins or something.
Using a lot of adapters may however introduce noise or delay into signals, which shouldn't be harmful but could result in some games crashing a lot.
Thanks P. The only thing I've noticed is the game takes an extra split second to show on the screen. Not sure if I'm just imagining that or not.
