There is a Flash game, Castlevania: The Blood Way, which is hard to find on the internet today. One problem with that game is that it uses external resources: it loads SWFs from a specific domain, including level SWFs (0 to around 11 levels).
I've the SWF: https://drive.google.com/file/d/1YE-S8ynq_mscVC5dblHneWbCZ6o3-E8g/view?usp=share_link
But the game doesn't play anymore. I tested it in the Ruffle player a few months ago and it worked, but the game stopped working now. I believe that the external resources have expired. Note that it doesn't work in the Flash Player projector too anymore.
I used FFDec a few months ago and was able to manipulate these external resources, but I lost everything. For some reason, now that I go to FFDec, I don't have idea of what are the domains. For example, I see that FFDec shows this ActionScript 2 code:
loadMovieNum("musics/introB.swf",1,"GET");
The problem is, which is the base path for this resource? I tried to search for, say, musics/introB.swf
in archive.org and didn't find anything. Not sure if this kind of search works in archive.org though. Any idea of what I'm missing? Because I was able to see the full absolute path of the resources...
