Created attachment 374708 [details] mednaffe-0.6.ebuild a gtk+ front end for mednafen only compatible with >=mednafen-0.9.30 when >=mednafen-0.9.30 has never been launched, front end will complain about deprecated mednafen version, because of the missing configuration file. A pre-requisite is to launch new mednafen version before mednaffe, perhaps the ebuild should warn through elog.
Created attachment 421538 [details] updated ebuild for Version 0.8
Why the debugger use flag on mednafen?
Because mednaffe-0.8 uses a command-line option which does not exist without. And then mednafen not be started.
games-emulation/mednaffe/mednaffe-0.8.ebuild is in portage.
