Despite a lack of time, the development will be continued by me and John. We had an email conversation about a roadmap and the goals for the next version.
One bigger issue to deal with, is that the development of advmame was stopped already a while ago. We might switch to SDLmame and try to use advmenu together with that. Next option is to use Wahcade! instead of advmenu. Lets see.
Besides everything emulation related, the kernel and support of more hardware is a topic which will be covered. Quick results can’t be expected, but at least we are again working on it!
