fake6502 Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[2.4.0] - 19-07-2022

Source code layout (and some test.c fn naming) updates:

  • removed comments from end of code lines

  • fn() { - moved to a new line

  • tests.c: typedef struct test_t -> test_fn, added prefix 'test_' to fn names

  • all addr/opcode fn's - a static option (by compile time #define option)

  • return's - ensured braces around value

[2.3.0] - 16-07-2022

Updated all global names to have a common prefix: fake6502_ to avoid conflicts with any other source files.

Changed the naming convention to be prefix_object_action:

setcarry -> fake6502_carry_set, etc...

zerocalc -> fake6502_zero_calc, etc...

[2.2.0] - 22-06-2022

Updated the documentation, created this CHANGELOG.md file.

Added

  • re-instate the counter: instructions

  • sectioning comments/dividers for .c and .h files

  • checks for invalid options settings/combinations

  • DECIMALMODE documentation

Changed

  • created structs: state_6502_cpu, state_6502_emu

  • renamed struct: context_t -> context_6502

  • mem[65536] -> void *state_host, for the host code to have it's own data struct/state area

  • renamed struct: opcode_t -> opcode_6502

  • move defines/macros into the header file

  • removed static from some fns, so the host code can use them to extend the library

[2.1.0] - 18-06-2022

Source code tidy up, for better inclusion as a source code library.

Changed

  • void step(context_t *c) -> step6502(context_t *c)

[2.0.0] - 2020 - 2022

Added

  • A test harness
  • CMOS support

Changed

  • Get reset to behave as on the real hardware
  • Some flag and interrupt related bugfixes

[1.2.0] - 14-12-2020

this fork was created:

https://github.com/omarandlorraine/fake6502

[1.1.0] - 17-12-2011

Small bugfix in BIT opcode, but it was the difference between a few games in my NES emulator working and being broken! I went through the rest carefully again after fixing it just to make sure I didn't have any other typos!

[1.0.0] - 24-11-2011

Fake6502 was originally created by:

(c) 2011 Mike Chambers (miker00lz@gmail.com)
Fake6502 CPU emulator core

First release.

This source code is released into the public domain, but if you use it please do give credit. I put a lot of effort into writing this!

If you do discover an error in timing accuracy, or operation in general please e-mail me at the address above so that I can fix it. Thank you!
