Emulator

Game Name? Sonic Riders

Game ID? GXEE8P

What's the problem?

While playing the story mode, up to the 4th race of the hero side, the emulation will completely hard-lock on the loading screen a few seconds after selecting the story from the menu.
Dolphin must be forced-terminated via task manager as you cant stop the emulation at all even though the windows are still responsive.

What did you expect to happen instead?

The game should be able to load correctly obviously, but more importantly Dolphin should be able to recover and fully terminate the emulation instead of it being stuck.

What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]

1. load up the game, save/load to a memory card etc,
2. proceed to game start > story mode > heros
3. the first 3 races will have to be finished if its from scratch, the bug occurs when going into the 4th

Which versions of Dolphin did you test on?

4.0-7138, a prior version would have a complete crash instead of an emulation lock, though I don't remember what build number

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

unknown/no

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

log, or what I could obtain;

note that the bug also causes the logging system to 'implode on itself' so to speak, log-to-file is completely non-functional and to obtain a usable log involves having log-to-console/window enabled and then disabled when the error occurs, otherwise it just infinitely grows

The 'export all wii saves' doesn't seem to be working for me to supply a wii save file to skip the first 3 races... or at least it doesn't give an option of where to export to like it ideally should and I haven't found anything in the documents > dolphin emulator folder...
