Crystal Cove Online - Black screen after initial load screen complete

[CasualPokePlayer]

Describe the bug

After the initial loading screen, the game ends up with a black screen. The music plays fine at this point, and some limited interactivity is possible (pressing Z or Enter has a pop sound effect indicating the next screen is reached, although inputs seem to do nothing else afterwards).

I'm using dropbox here as the game exceeds GitHub's zip size limit (as the game is ~40MB). Two links are provided here, the first is an unmodified copy of the game, and the second one is slightly modified to allow for the standalone flashplayer to play this game (and thus compare its results) (the modifications just being disabling the online enforcement and thus allowing flashplayer to fetch the swf files locally). The result is the same regardless within Ruffle.

Those last errors end up just getting spammed constantly.

Is seen it fixed in latest nightly, Are you sure did you wanna check again?

[CasualPokePlayer]

The black screen issue does appear to be fixed.

However, it now just reveals further issues in game:

1. Trying to select Save File 1 will not work; it will show an animation indicating it is pressed but not actually pop up a choose name prompt. Selecting Save File 2 or 3 works strangly enough.
2. When getting actually in game, the automatic cutscene with Velma does not start, and the player is not able to move at all.
3. You can press M at this point to enter the phone menu, although clicking the phone icon in the top right corner doesn't enter the phone menu like it should.
4. The phone menu defaults to the Help (? icon) menu in Ruffle, but it's supposed to default to the map (Globe icon) menu (as seen in flashplayer).
5. The phone menu can't be exited, and pressing all the buttons do nothing (at most making the sound effect indicating they have been clicked but not actually changing the menu).
6. The phone menu is supposed to be opened when the Flash window goes out of focus (as seen in flashplayer), while Ruffle does not emulate this functionality.

[CasualPokePlayer]

Actually, strangely enough, trying to test this out when RUST_LOG=warn,ruffle_core=debug,avm_trace=trace is set ends up just fixing these issues??? Although issue 6 still happens regardless.

[CasualPokePlayer]

Playing through the first mystery (I guess "first level" for this game) by using the debug logging workaround, I've encountered more issues:

1. The game seems to just suffer from performance issues, issues which are not present in the original flashplayer. Granted, this could be partly to blame with the debug logging I've ended up enabling.
2. The phone menu has achievements and past text screens completely blank, instead of having their normal contents.
3. At some point a bush icon appears on the top right of the screen, seemingly burned to that position on screen and moving with the player.
4. At some point in the first level, you end up stuck on a loading screen with this error popping up in the console (which I could assume caused the issue):
   2023-08-21T17:11:41.383143Z ERROR ruffle_core::loader: Error during movie loading of "file:///<path to game>/Crystal_Cove/Media_Game_7/Rooms/101_IN_02b.swf": FetchError("Can't open file file:///<path to game>/Crystal_Cove/Media_Game_7/Rooms/101_IN_02b.swf: The system cannot find the file specified. (os error 2)")
   This file doesn't seem to exist here in the copy I've obtained (which was originally just scraped off of Cartoon Network's servers as they still have the game there funnily enough). However, flashplayer doesn't seem to care and the game works correctly regardless. Checking Cartoon Network's site again anyways and that file doesn't appear to be present, so it probably doesn't exist at all.
5. Also problem 4 doesn't re-appear loading the save back up (fresh save only? weird one off?) (edit: fresh save doesn't have the issue, I would guess this is something else weird going on, maybe somehow related to 3?)

[CasualPokePlayer]

Seems like it's ruffle_core=debug causing the issues to seemingly be "fixed." If I only have RUST_LOG warning, I do get something useful indicating what's going on:
