Very nice Akuma! Feedback on 1.06 so far: Copyright / GPL the source (top-level comment block in the source file; separate from the usage output) Highly recommend Bash strict-mode : #!/bin/bash set -euo pipefail IFS=$'\n\t' In the usage text, brackets commonly indicate optional arguments, so only …

Thanks for the background and insight. A one-bit-fix is certainly nice! Will pass that onto the -X crew; the more eyes and brains on it the better.

The only DOSBoxes that are capable of reading FLAC tracks all use my CDDA patch (https://www.vogons.org/viewtopic.php?f=41&t=62203), which uses dr_flac , not libFLAC . You know that's not true, because you participated in the original FLAC patch thread: https://www.vogons.org/viewtopic.php?f=32&t= …

jmarsh, Regarding your recent GUS DMA fix for Quake, I've asked the DOSBox-X team about it here. https://github.com/joncampbell123/dosbox-x/issues/1961 I'm not sure if you looked at the DOSBox-X and Staging DMA implementations before going your own way, but am curious if you have comments / …

You might assume so since it's lossless, but like all codecs it still has a minimum framesize so if the total number of samples is not an exact multiple of that amount, padding gets added. The actual number of samples contained in the final block is stored in the FLAC headers but unfortunately not …

The closer you can get to the original target platform, the better -- because that's likely what the artists tested on. Late 80s and 90s game companies were like school kids trading pokemon cards in terms of re-licensing and porting successful games to new platforms. Meanwhile the original …

@fr500, I'm aware of how extensive the LFN changes are, and at least for me, back-porting it would be a non-trivial amount of work. Are you able to share why DOSBox-X with already-working LFN support is unsatisfactory for your needs versus "SVN + backported-LFN"?

Good stuff all round awgamer; is there a combined patch you can post that includes your performance improvement that latalante confirmed? Regarding 1000 microseconds, in theory you could then swap in SDL_Delay(1) and avoid the C++11'isms, as both delay one millisecond.

... ideally would come up with something that does the same as condwait, just not implemented as badly, or put more nicely, more sensitive, quicker to react that doesn't cause the same performance drop seen in the frame rate. Yup; that what I attempted at top of the loop: read the condition and if …

awgamer, The existing loop spins pretty hard; here are a couple changes that trying to mitigate that. Also moved domix bool to a counter mix_queue , so the mix queue can pile up - when we need to run the mixer back-to-back without another wait cycle. This can be the cases with PC Speaker PIT-mode …

Unfortunately hacking the the DC offsets in Blues Brothers Jukebox Adventure using the suggested hack for Prehistorik 2 doesn't work quite as well, and the audio is still left sounding broken, but in a different way. Also similarly, the 4-bit DMA transfer mode for BB JA also isn't nearly as …
