Added a lot of commenting to the CPU6502 definition, simplifying its construction. Added missing nullability modifier to CSElectron. Fixed bad-habit Objective-C style naming on the Electron's Interrupt enum.

Moved set_tape so that the inline definition of get_next_tape_pulse is visible to it. Also eliminated some dead typedefs.

Some data is marginally reaching the CPU from the tape.

As shown by the commented-out code, the aliasing-adaptation seems to be working. So something is wrong somewhere else.

Switched model for filter subclasses. Implemented test square[-ish] wave to check for obvious stream errors. None is clear.

Here, at last, is _some_ audio output, at least.

I'm not yet completely convinced by my approach to time basing, but it'll probably do? If so then this more or less gets me ready for a point-sampled filtering.

Edging towards audio output; the speaker is given appropriate input and output rates, and then updated with current divider and enabled/disabled status.

Made an attempt at correct timing, adding support for additional paged ROMs, added file association for .rom.

This is intended to be enough to start producing something of an output. But something's obviously still broken.

This at least now connects up a CRT, though it never talks to it.

Added just enough that this is probably a successful boot. I guess I'm going to need to get invested in graphics next? Hmmm.

You now get an Electron only if you ask for a new file. That'll do for now while it's the only thing that one might want to start without supplying a file. The 6502 now starts from a defined point — being reset. The Electron is starting to grow the absolute most simple buds of its memory map.

Started working on a shell for the Electron emulation, including factoring out the common CRT delegate -> Objective-C bridging, serial dispatch queue and frameskipping logic from the Atari 2600 shell.
