Alberta, Canada"notice NO lag with FCEUX."
notice is the key word there - you definitely have input lag
When you are just learning the game, it doesn't matter nearly as much, since the tricks you're doing won't be as precise - but once you're incorporating things like pipe jumps, it will start to matter a lot more that some number of milliseconds pass between pressing a button on a keyboard and mario responding. Your brain will adapt, but it's still more difficult to account for the timelapse than it would be playing on an actual console with a CRT monitor, where the input lag is effectively zero.
so optimizing an emulator to minimize input lag is a worthwhile thing to do, because even if you played emu on a literal supercomputer with no other programs running, you'd still have significantly more lag than a NES using a CRT
Also the word "INPUT LAG" is different than "LAG" how you would normally use the word. Input lag is just the response time between pressing the button and mario responding. The game could run smooth as butter and still have significant INPUT LAG.
Although clearly it's possible to be top-tier on an emulator with some level of input lag. @Tecate is a prime example of a person with a 4:56 that uses emulator, and always has used emulator - and can still reliably execute ultra-precise multiple-frame-perfect tricks like 1-1 FPG
In Pellsson's most recent version, this bug was fixed, but in earlier versions of Pellsson (for example v1.7) - Big Mario state is the small fire glitch version of big mario (so big mario with only 1hp instead of the normal 2hp) - like 16Bit_Ethan said
Also, I really like the word "megamush" - we should definitely adopt that word
