Title: [BUG] Crash during start when ./data/music/ has no music - Fixed
Post by: Simon on May 22, 2023, 09:10:24 PM

Test Release 3 - 20/01/2022, Linux version

• Download and extract the Linux release to new directory.
  
• $ chmod +x L2Player
  
• Copy an entire L2 directory over the same directory, so that L2Player and L2.EXE now sit in the same directory.
  
• Run L2Player. It extracts many files, then crashes with log below.
  
• Look at ./data/music/: This directory contains only one file, Readme.txt.

Expected instead: If I have no music, I can still play without music.

./data/music/Readme.txt says: "If you don't like the midi versions of the music, you can place .mod or .it (Amiga Tracker) versions here [...]" This sounds as if you want to ship midi music with your release. Do you want to ship midis?

Definitely a bug that one... It is supposed to start if no music files are available.

I don't plan to ship any midis, but they are default music flavour for the DOS version of Lemmings 2. I added the option to use the Amiga music files as they are considerably better to listen to :)

At this stage I haven't quite figured out the music format for the DOS version either.
