Peter Evans da4a82d8cf The disasm command now always sets disasm = true 
We should probably just not even offer this as an option in the debugger
then.
 2018-04-13 23:35:59 -05:00
Peter Evans 3834c1e112 The debug_break check was moved outside of the mos6502_execute function 2018-04-13 23:34:28 -05:00
Peter Evans 04e72486f1 We need to account for the track self-sync 2018-04-13 23:31:53 -05:00

Peter Evans 3887f52119 Clarify behavior of pop_stack 2018-04-13 16:22:58 -05:00
Peter Evans ebb5f068fd Always set the UNUSED and BREAK flags after execution. 
This change simply replicates the behavior demonstrated in AppleWin.
 2018-04-13 16:17:13 -05:00

Peter Evans ee2c9746c6 Add docblocks 2018-04-07 19:54:05 -05:00
Peter Evans 6e77e99813 Add ability to debug separate from pausing 
Also, pausing just pauses now; no debugger prompt is shown. ALT+P
toggles pausing, so just hit it again to unpause. Also, when things are
paused, you can perform other keyboard events (like quitting).
 2018-04-07 11:14:12 -05:00

Peter Evans 74aafb0d01 Reorganizing files into directories 2018-04-06 20:27:47 -05:00
Peter Evans f9d130ba97 Add an extremely crude method to slow things down 
It's not configurable, and not accurate to any particular measure. But
it's something for now.
 2018-04-06 11:49:54 -05:00
Peter Evans 281544bf43 Avoid polling for events until we're ready for a frame redraw 
This change drastically cuts the number of times we poll for events, and
consequently drastically speeds up the number of frames we can draw
within any given span of time.

In other words, we go from "this barely moves as fast as the actual
Apple II" to "holy shit this moves so fast".
 2018-04-06 11:47:54 -05:00

 2018-04-05 20:56:46 -05:00
Peter Evans 616bfdcc58 Implement rect change stack 2018-04-04 22:01:46 -05:00
Peter Evans d8e0159de0 Move hires colors into include file 2018-04-04 22:01:26 -05:00
Peter Evans c178e417b7 Separate window and renderer creation; use software rendering 
It seems _slightly_ faster than hardware acceleration for the uses we
have.
 2018-04-02 08:37:01 -05:00
Peter Evans 2d0952133a Add missing docblock comments, remove some dead code 2018-03-31 21:10:08 -05:00
Peter Evans 418950750f A very rough version of the correct hires render logic 2018-03-31 20:54:47 -05:00
Peter Evans 221d798c82 Remove online checks 
That doesn't seem to be how the motor on/off status works. This
basically stops the motor from actively spinning, but it does not
prevent the drive from basic operation.
 2018-03-30 23:33:30 -05:00
Peter Evans 2b8cdc7cfc Remove logging, always work on a drive in switch_drive 2018-03-30 23:05:24 -05:00
Peter Evans 6653da3c20 Rework overflow logic, and add missing handling 2018-03-30 23:04:21 -05:00
Peter Evans 0ccabda71e Rewrite SBC logic 
The carry handling was incorrect; carry is set if we went below zero,
but bit 7 is not enough to determine that. It follows that negative
handling needed to be modified accordingly. Overflow handling was also
incorrect.
 2018-03-30 20:07:24 -05:00
Peter Evans 07a8a385f5 Remove log statements 2018-03-30 20:06:59 -05:00
Peter Evans 54708e5110 Switch back to >= 2018-03-30 18:49:32 -05:00
Peter Evans a23c7321f5 Don't do certain operations if the drive is offline 2018-03-30 16:26:24 -05:00
Peter Evans d129ffed99 Logging on STA instructions 2018-03-30 16:10:15 -05:00
Peter Evans 523b9c4a03 Several changes... 
1. We have much more logging.
2. We were not properly turning off drives when we would get called with
   C0x8.
3. We now roll over sector pos if we are greater than ENC_ETRACK.
4. We now reset sector pos when we step.
 2018-03-30 16:07:58 -05:00
Peter Evans d2047457e9 Use log_crit() instead of log_critical() 
This change also removes the former log_critical and log_error macros.
 2018-03-29 21:45:25 -05:00
Peter Evans 7ca099d0d0 Open log file rather than use stdout 2018-03-29 21:42:38 -05:00
Peter Evans 20d33ef464 Change to erc.log 
emp is a much older name for the program
 2018-03-29 21:40:11 -05:00
Peter Evans 89a0f34ebe Add suite of log functions that map to syslog RFC levels 2018-03-29 21:39:13 -05:00
Peter Evans 5d55d5b258 Use a bitwise-and to determine carry 
A bitwise-and is what we do in most (all?) other cases; it's a bit
jarring to read the current logic.
 2018-03-26 23:10:57 -05:00
Peter Evans 8aef335f25 Remove unnecessary zero page code 
This is handled in the zp_read/write functions in apple2.mem.c
 2018-03-26 20:59:24 -05:00
Peter Evans d9be1d6ab2 We need to return from aux, or write to aux, immediately 
If we wait until later in the function, we may get caught up in the
check for ROM.
 2018-03-26 20:51:10 -05:00
Peter Evans 92ac77e8f5 Sort read switches 2018-03-26 20:48:13 -05:00
Peter Evans e51e643294 Force $C059 to do nothing 2018-03-26 20:47:41 -05:00
Peter Evans b2e9198ede Defensive conditionals 2018-03-26 20:46:55 -05:00
Peter Evans 81bcc7d973 We also need to check ACC in ASL/LSR/ROL/ROR 
And, possibly more importantly--opcode is not a bool.
 2018-03-25 20:34:12 -05:00
Peter Evans 3439ec51a8 inc and dec should work with a zero-address 
Just checking if (cpu->eff_addr) is not sufficient. We need to check the
address mode; only increment or decrement the A register if the mode is
literally ACC.

Peter Evans 64afcb2040 Rewrite phaser to use state transitions, whole phase states 
By whole phase states, I mean we no longer track if more than one phase

Peter Evans 474104085c Reorganize encoded sizes/routines to align with reference nibble output

Peter Evans 851bc85860 We should print the final line if from is still >= to 
This can happen if the region of to - from is not cleanly divisible by
16.
 2018-03-13 15:17:33 -05:00
Peter Evans ed32f73e98 Use another pointer to retain the original address to free
