Only output the textport every 16ms, and only if it's changed.
Be more consistent with throttling to ~1.023MHz by using a constant.
Fix bug where timeslice wasn't reduce when # of instructions was reduced
Merge lots of instruction improvements and fixes
Lift keyboard processing out of MAINboard
Make disassembler return a string - could be inserted into a queue for
later printing if desired
Add "banking" debugger command to exit the next time a bank is switched
Add abort_on_memory_fallthrough flag to force exit if memory access unhandled
Consolidate flag changes for SBC and ADC to "set_flags" command
Change "sw" member of SoftSwitch to "enabled" for readability
Change name of c{1,3}00_rom to rom_C{1,3}00 for consistency with rom_{D,E}000
Mark HIRES and MIXED flags as implemented; let them be caught in display
Add DEBUG_WARN flag
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.
