Descent crashes after Interplay logo...

[vonmillhausen]

When launching Descent Wii, I get music, I get the Interplay logo screen, but as soon as the logo finishes fading out, I get a crash:

Apologies for any transcription errors, my Wii is connected to a CRT and the interlaced text is kind of hard to read. Here's a photo, if it helps!

App is installed on my SD card (sd:/apps/descent); I'm using the DESCENT.HOG and DESCENT.PIG files from GOG:

• DESCENT.HOG: SHA1 = 4d6fb40e943f92574aba2c9fc1574330de89905b
• DESCENT.PIG: SHA1 = 53f6453d5a836cf660c6dcca0f636d46a28ee20c

I also have MP3 music files in the music subfolder; I do not have the Timidity stuff set up. I'm launching via the Homebrew Channel, but it also crashes in the exact same place if I launch via Wiiflow Lite. Let me know if you need any other information, or if there's any testing you'd like me to do 👍
