Yes, it seems DOSBox miscalculates MSF positions for all games, not just Destruction Derby. If you compare any BIN/CUE vs ISO+OGG/CUE, the MSF positions differ. The existing DOSBox code queries the second OGG's track length (plus rounding and padding), which it adds to the second track's start …

ClaudeSpeed, It was previously mentioned that DOSBox doesn't support multiple BIN files (which you originally mentioned using), where the audio tracks are simply raw rips (ie: not even WAV files). Good news is this patch fixes that; so you can play Redump-style disks straight away. Here's my full …

So while the game will play with the ~600MB BIN+CUE, it won't when using individual audio tracks (.wav, .ogg). What's the difference? It turns out Destruction Derby verifies each audio track's minute, second, frame (MSF) value, which are specified in the CUE file on the "INDEX 01 MM:SS:FF" lines, …

If you comment-in the three 'printStatus' calls in the callback, it will show the behavior of the buffer. If the 16KB circular buffer doesn't have enough data to satisfy the callback, it attempts to fill itself using chunked-reads from SDL_Sound. We see four of these reads initially here, followed …

At some point, floppy disks came populated with a setup/install exe file, and one or two big dat (archive) files. Your only option was to install to HDD.

You can choose sfx or music on the home screen using a hotkey toggle. A little graphical icon of a music note will switch to say FX. I think the default is music. As a kid, I would play the music for a while until I got sick of it, then switch back to sfx ("oh no!"). Unfortunately I don't recall …

PEBKAC :-).. That did the trick, thank you NY00123! .. In all these years I've only ever used -p1. I noticed this patch didn't have parent directories prefixed; so figured patch < ... would be equivalent to not stripping any directories.. but looks like -pX it changes the behavior as well. Cheers!
