The discrepancies seem to be a side effect of playing the VGMs back under emulation rather than actual hardware. Chaotic is the world of VGMs 😀

I can confirm the issue as well switching between 4-op and 2-op mode with some of my own files as well. (But I forgot to report it earlier, my apologies!) No worries at all! With my testing, I generally only play through a particular audio chip's VGMs ... it never occurred to me to try other …

I must say, I'm loving what SBVGM can do while really lamenting what it can't do. No CPU PCM support (or DMA/ADPCM support for SB16 or OPNA) seems bizarre when the MSX equivalent can manage. Thank you for the feedback! The lack of CPU PCM support is partially due to the original experimental nature …

Hello, is there any news on supporting the retrowave opl3 express? it uses the Yamaha YMF262-M chip. I tried using all command options while running SBVGM in DosBox-X (that supports the retrowave olp3) and none work :c If you've setup the RetroWave OPL3 Express to work properly under DosBox-X and …

SBVGM v1.42 is available from: http://www.oplx.com/code/ This update includes: Added preliminary OPL4 support. Notes For OPL4-based sound cards, it will be necessary to have used a utility (such as OPTi82c929_Driver ) that properly initializes the sound card to use the OPL4; SBVGM won't do this. It …

Maybe a bit off-topic, I reopen this asking for help. I've been trying to add support for ISA Tandy (SN76489) clone cards to FastDoom, but I haven't been able to make it sound "good". I don't have a real one, so everything I've done is tested on 86Box. Right now I'm using a LUT to do linear-to- …

Hello OPLx, I've been testing some Atari ST tunes on my PC-98, and came across the issue where samples (a.k.a. digidrums) don't play properly with SBVGM. No such issue occurs on regular VGMPlay, so I'm gonna assume that this is just a timing issue. Example recordings: https://www.mediafire.com/file …

Thank you! I'm coding an AY music player for DOS and like you I'm using a Game Blaster Card to output the sound but isn't quite perfect and the DOSBox GB emulation is not 100% perfect. No problem, have fun making the player! You're right about DOSBox's GB emulation. I haven't (yet) found a DOS …

Hi OPLx, I must have forgot that the SAAYM soundcard allow to play Genesis/Megadrive VGM, and most of them sound perfect ! But I realized that one of the very best soundtrack for the console was not plaing properly, it's the Dune music from Cryo. The music by Stephane Picq and Philippe Ulrich is …

Have you tried to add the -noscan parameter ? In version 1.35 OPLx implemented that function that comes in very handy when you have multiple soundcards with overlapping features and you want to disable "searches" and manually specify what devices you want in the mix. For instance "sbvgm.exe -a388 - …

I used the cyber1-2.zip files to check it out using an SAAYM and it seem everything is in there now! I also noted SBVGM1.32&1.33 would leave a weird noise at the end of the music but it was corrected in 1.41, but the noise is still somewhere. When using OPL3 to play YM262 files it end up leaving a …

Perhaps it's a bad VGM capture rather than a bug? I've attached a DRO version of highways that I captured for you. Maybe this doesn't have the issues you see. In your file, the 0xB7 register has index 0x75. After searching 0x75 after header There is only one occure: "75 00". This file also is …

Just a minor correction to what I wrote above. The FNum and Block value for operator 15 (tom tom) and the Multi setting for operator 18 (cymbal) affect the final output on operator 14 (hi hat). Operator 17 (snare drum) is only influenced by operator 14's FNum, Block, and Multi setting.

I will look today at snaretest file. One thing to keep in mind is that the frequency of the tom tom (operator 14) affects that of the hi hat (operator 13) which ultimately affects the snare drum's frequency (operator 16). The roadmap uses operators numbering from 1 instead of 0. Thus "(14)" means …
