| 2010-09-10 | Lazy, slow hack to FETCHW and FETCHWI becuase I forgot about endianness | Astrid Smith | |
| 2010-09-10 | Trying to get the zexdoc testbench to run. | Astrid Smith | |
| Now, at least, it's integrated into the build system and will be automatically included in built executables. | |||
| 2010-09-10 | Added stubs for putting the emulated screen into a TIOS-drawn window. | Astrid Smith | |
| 2010-09-10 | Completely patched zexdoc to assemble with SPASM. | Astrid Smith | |
| 2010-09-08 | Some more changes, spasm almost doesn't complain anymore! | Astrid Smith | |
| 2010-09-08 | Working on adapting zexdoc to work in spasm | Astrid Smith | |
| 2010-09-07 | Blank files for multibyte opcodes created | Astrid Smith | |
| 2010-09-07 | Added testbenches folder | Astrid Smith | |
| 2010-09-07 | Fixed the last movea that wasn't size-suffixed | Astrid Smith | |
| 2010-09-07 | IO port framework now works | Astrid Smith | |
| A68k is defaulting all my address moves to word size, rather than long. I don't know whether I've expunged all this nonsense yet, but I'm trying. This version executes an infinite loop which writes 'A' to port 00h. I've patched in a write-to-console function on port 00h, so this can be used as a sort of debug monitor. | |||
| 2010-09-06 | I actually have a Makefile now, thank you very much. | Astrid Smith | |
| 2010-09-06 | Assembler is picky about EQUR apparently ... | Astrid Smith | |
| 2010-09-06 | Registers holding emulated registers are now named. | Astrid Smith | |
| Hopefully 'esp', 'epc', 'eaf', and friends will be less troublesome than 'a4', 'a6', and 'd3'. | |||

| 2010-09-06 | Fixes to actually run code | Astrid Smith | |
| This is the version to run the first (trivial) infinite loop correctly. I hacked up the loader slightly to replace one of the (nonexistent) pages with a static byte array. z80 code executed: $4000: JP $4000 4000 c3 40 00 4003 This version also draws the opcode executed on the screen, to aid in debugging the emulator: move.b d0,$4c00+32*(128/8) Also, it turns out that I was mixing up the emulated SP (a4) and emulated PC (a6). That has been fixed. Further, it seems that movea defaults to a word operation in a68k. This led to pointer corruption, which has been fixed. | |||
| 2010-08-02 | HACK XXX UNDO LATER Made relative flag references absolute. | Astrid Smith | |
| A68k wanted to add relocations, but couldn't figure out how. Undo this later when it's speed time, as this (probably) slows things down a bit. | |||
