Re: SBVGM (DOS) VGM Player

Posted on 2023-11-15, 22:51

@NHVintage, no worries about the slow replies; hope you are feeling better. As DjLc pointed out, the SB16 can't play any of those VGMs. The reason why Tandy 1000 (SN76489) and Sega Genesis/Mega Drive (YM2612 & SN76489) VGMs work on the SAAYM is because the YM2151 and SAA1099 have similar enough …

@NHVintage, if the VGMs you played on your SAAYM worked, then they contain data for either the YM2151 or SAA1099 (or both). Those VGMs won't play on the SB16 since it lacks both of those sound chips. Please do share with us what VGM files you are trying to play; it will help us track down the …

Hi - I'm testing out a newly rehabbed 486 machine I acquired with MSDOS 6.2.2 and Win3.1 and having issues getting SBVGM (or SBVGM32, they're acting the same) v1.43 to work. This copy of SBVGM (and the vgz files) is on a USB stick and they work fine on my 8088 Equity I+ and its SAAYM card. I use …

Tested a couple of Sound Blaster 16 cards and found that one of them would only play OPL2 stuff, seemingly because of register initialization when switching to OPL3 mode. OPL3 tracks now clear register 8 and don't try to clear register 0xBD in part 2. (It's not clear from OPL3 Programmer's Guide …

So, funny story. I just tried it with SBVGM *32* v1.42 and it doesn't happen. 2-op plays fine after 4-op, but the bug only occurred with the non-32 version. It's already fixed so I'm not sure how much it matters, but what was the difference in handling between SBVGM and SBVGM32? Edit: It seems like …

Release alpha5 adds support for OPL3 and dual OPL3... though I don't know if there is any software yet which can play dual OPL3 VGM on real hardware. SBVGM struggles to play single OPL3 on my 286, so I might have to add OPL support to my own VGM player (which has been only for my custom OPN card so …

Added PRE logging support for YM2203 and YM2608 Changed order of YMF262 PRE logging data Added RP2A03 emulation on OPL3/OPL4. Fixed bug where APU channels may not play on VGMs that set …

"(and on OPL3 you need to get the order right, because the second set of registers controls how the writes are interpreted)" Prophetic words... From the Yamaha YMF262 Application Manual: "If NEW='1', OPL3 operation is selected and data is written when A1='H'. To use OPL3 functions, write NEW='1' …

So it turns out the issue was how the OPL3 was set once the program ended. During shutdown, I made the assumption that disabling the OPL3 "new" mode (address $105) would also automatically cause it to revert back to the OPL2 compatible state. Apparently (to my surprise) it looks like disabling the " …

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 …

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 …
