Floppy disks partially work:
apple2e -noaudio -fast -diskII disk2romfile {floppy1name,"none"} {floppy2name,"none"} apple2e.rom
Import nybblizer from Shamus but only DOS
Support floppy hardware
track motor stepper
enable
read
Add -noaudio (otherwise execution is throttled by waits once audio buffer is filled)
Only read ROM at D000 and E000 if C08X_read_RAM isn't turned on
RAMRD, RAMWRT, and ALTZP are implemented, note them as such in constructor
Correctly decode C08X soft switches
Implement a bunch more instructions
INC abs
LDY abs, X
SBC abs, Y
ADC abs
ASL abs
LSR abs, X
ORA abs
ORA abs, X
AND abs, Y
STA (ind, X)
LDX abs
CPX abs
EOR (ind, X)
EOR abs
EOR abs, X
STX abs
Throttle to actual number of clocks per instruction
Temporarily enable "Fake6502" instead of my CPU because there's an obvious difference
Better blink speed in interface.cpp
