importing settings

[LunaMoo]

That's not true, the only time old config would cause problems would be if a setting changed and was not renamed or setting considered unsafe was removed while being left as ini-only option and you were using it previously which generally doesn't happen as we try to avoid such situations while commiting changes;p.

Updating is as easy as installing new version over old one, when copying/extracting files manually you have to remember that you need to update not just the executable file, but also assets folder especially *.zim and *.ini files inside assets(important!), optionally you can also update shaders and lang folders. You don't have to update flash0 folder in case you used PSP system font(that fixes some problems in some games, but since it's copyrighted it's illegal to distribute and need to be copied from psp;p).

Savestates in 99% will be backwards compatible(rarely broken by commits from new people, but then quickly fixed) althrough abusing savestates as only way of saving game simulates infinite gameplay which is really bad as games aren't perfectly stable even on real hardware and as such normal in-game saves and emulation restarts from time to time are recommended even without updating, which sometimes might be required to get new things from new versions to work correctly.
