Catch ALTCHAR but do nothing about it
Catch VID80 (80VID)
Add aux pages to interface.cpp
Plumb aux pages through apple2e.cpp display_write functions
Implement 80-column text shader using aux page
On cold-start, force Button0/OpenApple on for a short period
This is how cold-start (disk boot) is differentiated from plain RESET
Add padding widget that pads another widget on all sides
Add drag-and-drop functionality to widgets and manage through GLFW
Honor current time through all widget methods
Fix character encoding in text_widget (especially for ' ')
Add floppy_icon widget that manages drag-and-drop and drive motor (activity) light
Later move to vector graphic or bitmap
Add floppy eject and insert notification from APPLE2Einterface
Add activity notification through APPLE2Einterface
Optimize with -O2
Mouse/Trackpad drag across the screen emulates paddles
Click on the screen emulates button 0
Ignore reads from C020 (tape out)
Add BRA instruction for 65C02 (maybe not necessary)
Disable audio in FAST mode
Throttle a little better when audio is enabled - stopped stutter
Widget for Apple 2 screen (graphics and textport)
Make box be vertical or horizontal
Add spacer widget
Fix calls to draw, click, drag, release to reflect whole screen being a widget
Fix#16
GLFW doesn't pass through Mac CAPS lock key for some reason.
CAPS button in GUI works, though.
Implement more instructions, mostly for ChopLifter
DEC abs, X
INC abs, X
AND (ind), Y
AND abs, X
ROR abs
Now ChopLifter needs unimplemented SED! Probably uses decimal mode while printing score.
Set "then" at end of CPU loop to try to throttle better. Not sure it helps.
Fix ADC abs (was accidentally adding Y to address)
Also handle bank switch registers on write
Initialize CPU6502 registers to 0 to match fake6502
Avoid spurious differences
Implement more instructions
ADC (ind), Y
ADC abs, X
ORA zpg, X
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
Fix up clock timing on absolute-indexed, indirect-indexed, and branch instructions
Emitted clock ticks now match up with emulated and video recorded beep sound
(code to save off and postprocess ticks not checked in)
