SDLMESS
The latest version is 0.123. Note that this fully-packaged version is deprecated due to the fast-moving nature of MESS development, but I’ll update it on integer MESS releases. New in this version: all the stuff from SDLMAME 0.123 plus some nice core updates.

Note that the SDLMESS components are an official part of the MESS Subversion repository and the checked-in version there is kept up to date, so that’s the recommended way to get SDLMESS while saving some bandwidth.
