[Issue]: Mario Kart Double Dash (USA) error when loading over FSP

[coolbho3k]

Describe the bug

When loading Mario Kart Double Dash (USA) over FSP, it crashes right after the progressive scan selection screen with "An error has occurred" error.

Sometimes, the game is able to load to the intro movie. This is really rare for me.

My config:

1. Loading from my Synology DS923+ using the frenskefrens/fsp-server Docker image with default configuration. The NAS and GameCube are connected to the same 1 Gbps switch.
2. This happens with both an nkit ISO and clean ISO. Both ISOs load from GCLoader fine 100% of the time.
3. Other games seem to play from FSP fine, the only one I found that crashes so far is Mario Kart Double Dash.
4. I tried an MTU of 1500 and 9000 (jumbo frames are enabled on the NAS and switch)
5. I'm using the official Nintendo BBA.
6. Swiss v0.6r1622 booting from GCLoader

Steps to reproduce

1. Try to load Mario Kart Double Dash (USA) over FSP. I used the frenskefrens/fsp-server Docker image.
2. The game crashes right after the progressive scan selection screen with the below error.

Expected behavior

The game is able to load properly
