Re: SBVGM (DOS) VGM Player

Hi OPLx, I hope I did not stressed you with that issue, I know is must be the third time I bring it to your attention. Having an hobby can become a burden if you feel an obligation to work on it and it's not what I'm trying to achieve. On the opposite, I was in the impression that to document the …

@ElBrunzy, what you for making the recordings and looking further into the issue. The main cause of the incorrect bass sound on the SN76489 is that the Sega Master System implementation is different from that of the SN76489AN. At the time I added support for the SN76489, I did not have actual …

About the set blaster bug, I think any random (but wrong) set blaster= settings might cause the player to crash. I'll try to give you the info if I can find them. About auto-detect of audio chip really, I think you should add a way to disable them or ask to detect them, like "sbvgm 123.vgm +t2c0 - …

I had many difficulty using sbvgm 1.33, to boot from : I like how it display it when all synth needed playing a music, but my request being : can it also display it when it fail at matching a play ? Also why I have to specify -t2c0 while opl388 is autodetected ? This dont make sense. Why some …

Alright, figured as much. Just trying to stretch my Tandy 1000 RSX into as many corners as I can with VGM playback. Thanks though! I haven't tried it out, but this tool might do the job: New VGM to MIDI + OPM + SYSEX tool for YM2151 This sorta works, it is a nice way to get some YM2151 patches onto …

I'm not sure if it's possible but do you think FB-01 and/or IBM Music Feature card support could be done? Not sure how close the YM2164 is to the YM2151 but it would certainly be cool to utiluze those devices for 2151 VGM, and if not then VGM of the few games they support. More just wondering the …

Hi, Thanks, Is the PS1 Tandy compatible ? I see this in wikipedia: The PSG used on the PS/1 Audio is unknown, but sounds very similar to the SN76496 used on PCjr and its PCjr 3 Voice protocol It is more simple for me to do a port list, otherwise it will never be finished :) The PS/1 audio chip …

It takes a while to grasp how everything fits together; it's what made the old PC hardware frustrating, yet interesting and challenging. If my understanding is correct, XT class hardware didn't use port 0xC0, but AT class hardware does. SBVGM takes the safe approach when it auto-detects the …

I'm still learning about it all, I was in the impression that 3tool.exe was a kind of init tool that redirect call from AT DMA2 computer to another port via a TSR so on an AT you could only have PSG on 0x2c0. But now I see sbvgm work without it so you dont really need to run it. It also use as a …

The older versions of the program likely exhibit this. When I first added SN76489 support, I had used DOSBox to test and it didn't have the issue. I just need to make time to do some additional checks with actual hardware. I started to test the tndy nano sn76489 with sbvgm and older version (1.15 …

I'm pretty sure those "Bell" thing would not be a matter using the sn76489 chip and I will try it using older version of sbvgm to test it, but I'm pretty certain it will not be a problem... who knows ? That bring me to the question about how did you fixed the issue with saa1099 audio chip ? The …
