MANIP LINGO:

gold = gold (this manip does not work on Silver/Crystal, they have their own manips)
gfskip = buffer Start when booting the game so you skip the "Game Freak Presents" screen
backoutx = backout of the NEW GAME/OPTIONS screen to the title screen (buffer with B), then buffer back to the NEW GAME/OPTIONS screen (buffer with Start) x amount of times
waitx(opt) = wait x * 4 frames on the NEW GAME/OPTIONS screen, then enter options and buffer a backout of the options (buffer backout with Start)
(the NEW GAME/OPTIONS screen only accepts inputs every 4 frames, so it's only a 4 frame window for timing waitx)
newgame = buffer A to hit NEW GAME

Approximate Flowtimer offset:

GSR/GBP: 28259
GBI: 27187

Adjust as needed, 4 frames = ~67 milliseconds
