In that case, good luck getting a working native version anytime soon, sadly. 🙁
As an alternative, users could try running Genesis Plus GX (which has surpassed Kega in terms of accuracy and is actively developed – but lacks 32X support) through RetroArch or BizHawk (which uses an outdated fork of GPGX). Never really tested this, as I don’t need to as long as I have Kega working perfectly through Wine.
