WarioWare Inc. Mega Microgame$! FAQ 
 
Q: What are you playing on, it is emulator?
A: No, I play on a Gamecube through a Gameboy Player using a Gameboy SP as a controller.

Q: What is with all the resetting?
A: The resetting is the save time in the menus by skipping cutscenes. Basically every time you beat a boss, you reset to go back to the menu faster. Then enter the game, and reset again the skip the "loading" cutscene where it updates that you just beat a boss. Enter a new level, then reset again to skip the cutscene that level has, then go back in and actually start the level.

Q: So how do you go fast in this game?
A: As mentioned above, menuing plays a part. In terms of the actual gameplay, the minigames don't have an effect whether you win or lose, you still have to wait for the timer to run out. However the bosses all have some element of execution to them, and a fair few have RNG elements to them as well. So going fast on them is key.

There's also another element of luck that plays a part in the Jimmy 3 stage, as his secondary stages are mashup stages of the stages before them, so what minigames you get can determine how fast they finish. Orbulon minigames take way, way longer than any other stage, so getting a lesser amount of those on Jimmy 3 saves a lot of time

Q: What's the luck on the bosses?
A: For all 3 Jimmy bosses, how long the pause is before he throws another punch is random (These are the biggest ones). For 9-Volt, whether you get fast or slow pitches is random. For Orbulon, whether you get answers that have no cursor movement or not is random. For Wario, where you get the boulders to attack is random.

Q: What is WR? And why does any% end before the final split?
A: http://www.speedrun.com/wwi 
Basically, the category "All Stages" involves doing everything in any% and the 4 stages after it (Easy, Thrilling, Hard, All Bosses). It's far less optimised/competitive though, I just figure I may as well do runs for that whenever I finish an any% run.

The any% one is the one I'm really going for, need another 2 seconds which may not seem like a lot, but it'll take a very good run to get those 2 seconds. 
I've already got the best All Stages time, but I want a deathless run of that, which would be under 41 minutes.

Q: What is with those split icons? What does A and C mean?
A: This is a grading system for all of my splits. I'm sure you are familiar with grades, A+ being the best then going down from there. So the idea is, if the split has an A+ next to it, my time there was really good and would be very difficult to beat. If it's a C though for example, it was quite poor, and I should be able to save time there pretty easily.
 
This way, everyone watching has more accurate information on where I can save time, and where I should be making up time. Also that all time loss is not equal, as losing time vs an A+ split isn't really that bad, whereas losing time vs a C split is really bad. It'll probably take a while for a lot of people watching to pick up the meaning so I will appreciate everyone who explains how this works (correctly) in chat to new people.
