yeah you can either run it at a steady 60fps (which is slower than the original snes, which is about 60.08 fps) and lose about a second every 10 minutes or you can select to run it at the exact same snes speed but at a cost of a screen tear every 10 seconds (single buffer) or at the cost of a frame drop every 10 seconds (full buffer... this also adds "no more than" a frame of input lag)

anyway, I found this answer on the Zelda: ALTTP forum https://www.speedrun.com/alttp/thread/fu8mj/1#s9uiz so i'll go with that.

Hi I was just wondering if the Analogue Super NT is allowed for submitting runs... And if so would that fell into console or emulator category? keep in mind that the console is not a software emulator but an FPGA representation of the snes...

Thanks
