As a Ruffle developer who in my day job maintains some Flash-based websites, I'll note from experience that AMF serialization/deserialization in Ruffle has some definite issues, so that may be the issue for your games (the websites I maintain use https://metacpan.org/pod/AMF::Perl). See https://github.com/ruffle-rs/ruffle/issues?q=is:issue+state:....
replyAs far as I've seen, Ruffle never even makes the call out to the server... so at this point I don't think it's a serialization issue although some of what's in that list could potentially cause problems. The Ruffle compatability docs still say that NetConnection has 90% coverage... except for the .connect() call itself, which kinda makes me wonder why bother covering it at all?
replyThat documentation, for stubs, can be somewhat misleading. It just looks for the presence of an avm2_stub_method function call anywhere in the method, which may mean a method that's entirely a stub, or as is the case for NetConnection.connect, a method that is stubbed under specific conditions. NetConnection.connect is stubbed for specifically non-null, non-http commands (generally this is RMTP/RTMFP). See https://github.com/ruffle-rs/ruffle/blob/df11c2206bc6be0a329...
replyI am jolted, nearly shocked, that in 2026 you have to maintain some Flash-based websites. Can you share?
replyI mean I could decommission them but they're educational websites related to DNA and bioinformatics with interactive animations and my boss has a certain fondness for keeping them running if we can, as we used to get a number of grants that funded creating them in the first place as a nonprofit educational and research institution.
