Happy to report we are seeing some pull requests from other users in the community. Recent updates to the build process on Windows have been merged, as well as some minor fixes. I hope to test with a newer wxWidgets library (that is known to address some mouse slowness) and will tag a new release.
Hoping to dig into the ROMless mode issues at some point, and/or at least update documentation to encourage the use of a ROM file to avoid those issues. Support for older operating systems, including 32-bit, PowerPC, Solaris, etc. is slowly being removed, whether it's in the documentation or the code itself to help simplify the codebase.
