Yea, regarding X6, the clock stops when you enter the boss' lair, that's why I edited the rule. The Mavericks don't have to be defeated, you just have to exit the level via their lair (Not the Nightmare's alternative lair).
I don't know about X5 though.
Regarding the New Game+ and weapon training, it doesn't need to be stated.
Zero 1 is counted in the S-Rank rules, it's just not under S-Rank. Just as long as it's there, it's fine, but yes, rules need editing, thanx.
You are able to record ROMs via VBA (Virtual Boy Advance). Open VBA, then the ROM. Go to Tools > Record > Start movie recording.... Then play until you wish the video to end. When you want it to end, do the same procedure, but click Stop movie recording....
For the NES and SNES, I' not too familiar with those types of emulators.
