@BuZz I unintentionally got two failed installs so I'll share them as they had your exit code fix. They failed differently so at least it's something. :) The N64 emulator exited with 1 as expected, but Splashscreen exited with 0 (it didn't continue to install but I don't know how to tell when it's done done). Edit: It should end with Info: [message] on success?
1: basic_install exited with 1 when mupen64plus failed. Ran on Debian with amd64. See full log.
