There was a version of Cobra on a Plus 3 compilation disk: The Magnificent Seven, which must use some alternative to the floating bus.

Just checked. The version of Cobra released by the Hit Squad doesn't use floating bus. -

There's nothing wrong with SPIN's floating bus emulation. -

Yeah, you're right. Seems the latest version on WoS is still v0.41, and that has a pretty poor implementation of the floating bus. -

You're not missing anything. Dunny accidently built at least the last couple of releases using the old contention/floating bus code. Believe me, your game does not flicker at all when built with the correct source :) -

SPIN & port #FFHow to solve a problem with port #FF on SPIN? This prevent me from creating correct RZX-file with Short Circuit, part 1.
What problem are you having?
Port $FF is an unattached port - it will reliably return $FF on a read in +2a/+3 hardware, and floating bus results for any prior models.
