SZP is a RAM, not a ROM
Improve backed_region by using a RAM/ROM enum instead of a readonly boolean
irom is now i1rom (backing 0xC100)
Add i3rom backing 0xC300 and implement C3ROM switch
Add -debugger flag to start in the debugger
Don't step CPU when "debug" command processed
Remove "go_verbose" function
Allow a lambda to enable or disable the region
pass a name
Put them in a vector on initialization so they can be probed in a for loop
Currently has a bug - regresses
"clean" Makefile target
Rearrange DEBUG constants so least bits trigger output with most impact
New "implemented" bool SoftSwitch
Add page2 handling to textport (untested)
Separate out "region" encapsulating address start and end for convenience
Factor out "set_flags()" for most common "flag_change()" sequences
Move comment with instruction opcode onto case for compactness
Remove old disassembly in favor of open source disassembly
Run about as many 6502 instructions as can run in .1 seconds running at 1MHz, measure the duration, and then sleep the difference between the duration and .1 seconds of wall clock time.
