Building libretro-mame

Install build dependencies

Windows

1. Begin by installing and configuring the RetroArch msys2 build environment as described in that documentation: https://docs.libretro.com/development/retroarch/compilation/windows
2. From the msys2 console, install python with the command pacman -S python

Clone the repository

git clone http://github.com/libretro/mame
cd mame

general make syntax

Platform-specific make syntax

Building a previous version

!!! Important
If you want to build a previous version of MAME, begin by making sure that you can build the most recent version.

Once you have built the most recent version of MAME to establish that your build environment is complete, reset the contents of the repository to a clean state:

make clean
git reset --hard

!!! Warning
These commands will delete any files in your mame subfolder that are not in the libretro/mame github repository.

checkout the previous version source

See the section "Commit hashes for previous versions" below to find the correct commit hash. For example, if you wish to build MAME 0.205, the corresponding commit hash is b691c38.

Use this commit hash and the git checkout command to roll back the source to your chosen version:

git checkout b691c38

Commit hashes for previous versions

I think that's a good idea. I frequently tell people "checkout the desired revision from git and compile" but I don't think anyone has ever taken me up on it :P
