Added a quick snippet test, discovering that I've cut a cycle from read/modify/writes.

Added a couple of timing tests, both of which seem to pass for now.

Removed the implicit reset upon 6502 startup, adding a reset line. Hence all tests now pass again. Added an empty shell for timing tests, the all-RAM 6502 now counting bus cycles.

Made an attempt properly to emulate the RDY line and the Atari's use of it.

Trying to fix my RDY line emulation. Switched to PAL timings, at least temporarily, since it's starting to make a difference.

With a slight tweak to the informal protocol used for 6502 memory access cycles, ensured the wait strobe actually halts the CPU, to give a more accurate linking of machine time to real time.

Switched to idiomatic source name, ensured latest project name is in all appropriate header places, threw texture coordinates slightly into the shader mix.

Imported what little I have so far in the way of a memory-access cycle complete 6502 and just enough of a pretend Atari 2600 on top to be able to see some playfields in ASCII art.
