The flashcart does not demand 2A. The SNES voltage regulator shuts off at 1A as a safety feature. I measured my flashcart and SNES using less than 650mA total from the power supply. Real carts were drawing less at 450-550mA. Yes, NA SNES and SFC need negative center or the console won't power on. You can use a guitar pedal polarity reversal adapter on a positive center supply that fits SFC. 1A is plenty, you just want some headroom above 650mA so the supply lasts longer and to have protection against short power spikes. 25% is enough. Electronics only draw the current they need. 1A supply works exactly the same here as 1.5A or 2A.
