Tried to compile ColEm w/ help of instructions in post #27092 above. Only source code version currently downloadable is ver. 3.3. I believe I have RetroPie ver. 3 (dunno how to check that, installed RetroPie last week). The make command exits w/ an error message. So it’s not possible to use ColEm for the Colecovision.

Some people advise to use Mess, advMess or even FBA incarnations for the Colecovision. I can not find instructions on how to install/compile those on RetroPie anywhere unfortunately.

Any progress on the Colecovision front?

P.S. Found the source code for ver. 2.9 of ColEm via the Wayback Machine (http://web.archive.org/web/20140806040849/http://fms.komkon.org/ColEm/) (zip file included in this post for others to try and compile). Tried to compile that one. This one indeed compiles successfully!
