This hack isn't horrible, but it falls back on a lot of standard (read: bad) Megaman hack "I can do it, too" ideas. I have to agree with Bisquit on that. For the most part, it's also not
that difficult, but that was apparently the author's goal. Overall, I'm actually supporting Bisquit's refusal of the hack.
A much better hack for a TAS would probably be the better-known Rockman Exile (I think a TAS of this was started, but sputtered and died), or the not-so-well-known
Rockman Exhaust, which seems rather well-done to me. (Note: There's an FCEU movie of a normal run of the game there, but I haven't been able to watch all of it. The movie desynced when I tried to watch it with a patched "Rockman 2 - Dr. Wily no Nazo (J)" ROM. It will play through to the second Wily stage. I haven't yet figured out which Rockman 2 ROM the player used to make his movie.)
