Thomas Harte
a15af1df5e Attempts to use the other bit of disk drive control, the 5.25"/3.5" select. 
For the record, the ROM thinks it finds some Smartport devices and then attempts to talk to them. Since none is present, it blocks forever.
 2020-11-11 17:55:50 -05:00

b3ab9fff9b Imports a custom-built copy of Klaus Dormann's 65C02 test, with only 65816-compatible parts. 
Thereby fixes another couple of 65816 issues — BRK(, etc) not clearing the decimal flag, and `TRB d` being mismapped.
 2020-10-19 19:27:16 -04:00
Thomas Harte
99eba2f8ba Ensures intended 65816 exception behaviour. 
i.e. the relevant micro-op sequence exists, and its operation isn't lost. Also sets the 65816 by default to jump straight into power-on, not to execute an instruction first. That shouldn't make a functional difference, but it makes debugging easier because it makes startup fully deterministic.
 2020-10-18 14:43:47 -04:00
Thomas Harte
b22aa5d699 Starts transcribing the addressing examples I have into tests.

525233e10b Ensures all input data types are parseable in Metal.

df89a8771c Makes an attempt to have the emulator fill the actual GPU buffers. 
Not that they're drawn from correctly yet. I might first take a run at a new quick-path output route for emulated RGB displays, that just seeks to use the scans directly. No intermediate buffers. Besides probably being a good feature, it'll be a good way to ramp further up with Metal.
 2020-08-08 22:49:02 -04:00

The Amstrad CPC and ZX80/81 have made the jump so far, subject to caveats. The macOS build is unlikely currently to work properly.

ead32fb6b2 Return to old behaviour if --logical-keyboard isn't specified. 
This is at least until I'm more confident in the keypress/text input merging. Also, switches to a vector for intermediate keypresses, to ensure order is retained even if timestamps are absent.

b76a5870b3 Moves drawing into the next timer tick after retrace if sync locked. 
... which should mean it occurs within 1/600th of a second of announced retrace, which I assume always will be less than the retrace period. So: does the frame buffer update during retrace.

This should completely eliminate tearing for machines that can be synced to the native output rate.
