Initial Comment:
Just to prove I'm not completely dead, a patch to a)
detect when a loader is occuring (basically, two INs
within 100 tstates of each other with B being either
incremented or decremented) and b) run the emulator at
the maximum possible speed when a loader is in progress.

Caveat: any sound sychronisation will still occur, so
you'll probably need to turn sound off to see any
effects. This shouldn't be too hard to work round.

Possible extension to this patch: automatically start
the tape when a loader is detected, and stop it when
the end is detected.

It'll need a bit of tidying up before it's committed,
but I think it's basically functional. I've tested it
on some games (Ant Attack, ATF (notable as it
decrements B rather than increments it), Bomb Jack,
Bubble Bobble, Cobra (both Alkatraz and Speedlock
versions), Colossal Adventure (Jewels of Darkness
version), Elite, Exolon, Head over Heels, Joe Blade,
Midnight Resistance, Rainbow Islands, Skool Daze and
Star Control) and it seems to work on all of them, but
any more testing appreciated.
