Wow that’s some setup you have Mark

I’m just doing this on my Mac Pro using Xcode as my editor, I made a nice makefile for building my Pac Man code that also starts Mame for testing in debug mode.  That’s about it.  My job has nothing to do with coding.  I only code for fun.

Thanks for sharing your wild setup,

Also they're supported on most CPUs by the IDAPro disassembler, which means I can directly re-assemble stuff I've reverse-engineered using IDAPro. It also has decent macro support and a separate linker. And they run on several OSes, including Windows and Linux and don't require 'installation'.

These may include graphics conversion utilities, file format (bin,hex,etc) utilities, RSDOS BIN file formatters etc. These are all written in generic C (using MINGW) and can be invoked from the makefile where appropriate.

I then launch MAME/MESS from the same command line (most often using <UP-ARROW><UP-ARROW><ENTER>) and if I'm testing my cartridge image, it's running immediately, or if I'm testing my floppy disk image, I typically unthrottle MAME/MESS and execute the loader.
