Additional information

This game is part of a bigger effort to support 4399.com games. There might be other issues with this website, from how it handles Flash checks and many CORS issues. Unfortunately, some games cannot be easily debugged on desktop because the swf download other swf or do requests while logged in.

If Ruffle is not detected try to reload the page multiple times because of the known race condition on the Flash check. To avoid refreshing try this Tampermonkey user script 一键下载 flash 游戏 (greasyfork.org)

To solve these issues refers to previous issues such as:

https://github.com/ruffle-rs/ruffle/issues/13943#issuecomment-1835074616 - Race condition discussion
https://github.com/ruffle-rs/ruffle/issues/14578#issuecomment-1873523939 - Ruffle detection issue
Edge/Chrome flag to temporarily disable CORS --disable-web-security or use https://chromewebstore.google.com/detail/allow-cors-access-control/lhobafahddgcelffkeicbaginigeejlf
Disable antidebugging with https://greasyfork.org/en/scripts/440060-anti-anti-debugger/code or Deactivate breakpoint
Disable second antidebugging manually
When running the downloaded .swf from desktop to debug, use --referer "https://www.4399.com", the correct --spoof-url (usually the page link) and --base which is the relative URL where other resources are fetched.

Game actually works fine on Desktop and Ruffle demo website. Only on 4399.com, after the loading bar finishes, you just see a black screen and you need to click to proceed to play. It could be a problem of interop with the website to show ads.
