I'm starting this post on a rather vague basis since I cannot provide any exact details, but here's the deal:
I've made tracker music for the titles of PopCap Games
. In a couple of titles they used BASS.DLL to play the music, but they then switched to FMOD.DLL due to "stability issues". According to them, BASS.DLL has caused random crashes and lock-ups on some computers, even blue screens and instant reboots. As an interesting detail, many of these problems disappeared when the .IT file, originally composed in ModPlug Tracker, was loaded and re-saved with the old Impulse Tracker.
I'd muchly prefer they used BASS.DLL, firstly because it supports filters (which FMOD.DLL doesn't), and second, because we could then pack the song files even smaller using MO3. But they refuse to switch to it due to the problems they've been having.
I now wonder, how widely is BASS.DLL used in shareware games? Are they all having similar problems with its stability?
