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.
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
Add button class to interface
Check for press/drag/release of RESET button
Add FG and BG color for textport shader (for active button)
Handle RESET and REBOOT events in main loop
Multiply by a matrix in vertex shaders to convert from pixel
coordinates to window coordinates, moving that operation out to a
centralized place in the application.
Factor out shader binding for code simplification.
Factor out making vertex array in anticipation of UI buttons.
Change "mode" to "display_mode".
Fix setting of glViewport on window resize
Add lores shader and implement in redraw
Handle inverse text, but it indicates glyph lookup or raster location is off by one, not sure what's going on there.
Move to GL 3.2
Draw a quad with shaders depending on the mode in that part of the screen
HIRES shader reads from hires texture
TEXTPORT shader reads from textpor texture and indirects through a font
to get pixel values
MIXED now supported
Still to do: BLINK text, INVERSE text, LORES, gang up HGR memory updates
Why doesn't cursor flash the checkerboard?
