I'd like to apologise for the delay. Although I had previously brought both the Windows and Linux versions of Retro Messenger to a stable state, I was unfortunately too gung ho when it came to the most recent update, leading to the Windows version of RM stable, whilst the Linux version is currently buggy. It works, but isn't at the quality I find acceptable, and so I will need a few more weeks to work out the bugs. Thank you for your patience
