Introduce GLEW for GL extension management
Fix warnings about "&" used in logical-AND with precedence likely not matching programmer's intent
Fix a GL shader type incompatibility uint vs int in lores shader
Add Makefile.linux
Move all libao operation into interface.cpp
This should have the result of removing all AV and GUI code from apple2e.cpp
OS code remaining in apple2e.cpp should basically be only file I/O, console I/O, and chrono.
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
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
