Murks64

Murks64 - a small and crude, bare-bones (and only partial) "C64 emulator" written in C++17 and running in a console.

Features

Emulates:
- CPU NMOS6502 using "fake6502" (as submodule, added from https://github.com/omarandlorraine/fake6502.git)
- 64K RAM, as well as Basic and Kernal ROM
  - Relies on a ROM listing from https://github.com/mist64/c64ref.git, which is "baked" into the source code.
  - Therefore, the executable can run on its own, without the need to load any files (ROMs etc.)
  - However, it is possible to load binary ROMs from a subfolder "data". (No ROMs included here.)
- "Emulates" The VIC-II rasterline register, which is required for BASIC to start up.
  - Emulation is probably too strong a word, the register is just incremented every few CPU clock cycles.
- Nothing else! (At least for now.)
  - No VIC-II => No Graphics!
  - No SID, no Datasette or Floppy, no Cartriges...
"Debugger"
- Probably not worth calling it a debugger, but it allows looking at the CPU status, Stack and RAM.
- Provides Breakpoints, single-step and continuous execution.
- Crude "Disassembly": It just uses the current PC address and looks up the correct line in the ROM listing.
- NO Assembler!
- Want to see the screen? ...sorry!... Well, you can do a memory dump... (eg. "m 0400")
Hobby project flair
- Questionable future.
- Probably tons of bugs and missed opportunities.
- 100% I will be just on a 4-month vacation when you have an urgent question.
- Don't look at the code, if you don't want to catch a disease.
- License situation completely unclear (to me...) Probably GPLv2?

Requirements

OS: Windows or Linux (Maybe more, but what do I know...)
Compiler: GCC (with C++-17, so probably 8.x minimum required.)
- On Windows tested with MSYS2 / Mingw64
CMake 3.14 (probably)
Clone with submodules: git clone --recurse-submodules https://github.com/Webfra/Murks64.git

Trivia

"Murks" is german slang for "mess" or "botch"...
