I honestly don't understand why these cheats were here. Preventing
enemies from moving breaks some missions and doesn't do anything
useful, and preventing enemies from firing is basically no better
than the invincibility cheat (and might even be worse, if it applies
to Sid; I didn't check).
This is mainly because the old "limit" functions were all restricted
to certain types, which is incredibly silly given how simple they are.
Macros are much simpler, and a warning gets raised if they're used
improperly with multiple types, anyway.
In the process, I also found and fixed a bug: it seems the original
author intended for escaping enemies to gradually accelerate to
fleeing speed, but the low value was indicated as the max value, and
the way limitFloat was written, that caused the max value to be used
(it was supposed to reduce the speed to a minimum of -15, but it
instead effectively assigned the speed to -15). It might be a good
idea to re-implement the old buggy behavior intentionally; depends
on whether the acceleration of jumping looks better or worse than
just immediately going to jump speed.
Kline previously had a maximum of 500 or 750 health, and uses some
hacks to cause it to flee just as it was destroyed, and to advance
to new stages in the final battle.
I've replaced this with a much larger amount of health, and progression
being based on how much health he has.
Also some other stuff.
This is silly. I can see that someone decided to restrict targeting
to one ship as a difficulty setting, but that's not a very good way
to achieve different levels of difficulty.
Also added more music and slowed down RE.ogg.
