I play games in D-Fend Reloaded, v. 1.4.4. I wanted to record (Ctrl-F6) the beautiful melody which starts playing in the labyrinth when Brandon turns into a ball of light after repairing the altar. It doesn't work, the resulting "sound" file is silent.
The game has three executable files: crack.exe, main.exe and setup.exe. I use main.exe for running the game. In other games recording music works fine, at least in all those where I tried it.
