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 something unique and very good. There are many version and I would suggest you take a look at it if you do not know it already. The game is turn based strategy, I think the best version must have been on PC.
Unfortunately the music is only playing some random sound. The files of that game are very big and if I render them as ROM on the Genesis it take three cartridge to hold it. But the player can play other big music, so the size must not be an issue. I read your note about the YM2612 support in SBVGM.TXT and I see some limitations : I dont think there is sample playback on those VGZ, the frequency range do not seem like a problem. So my guess would be the SSG-EG envelope thing or the LFO that must be missing on the YM2151. The VGM are huge and the musics is not particularly complex, so that's why I think maybe the problem could be a controller like the LFO or the SSG-EG ?
Using VGMTool 2 R5 I could not find anything particular but I think there is another VGM tool analyzer that could help see what's the problem with that soundtrack. Right now vgmrips.net is down and I do not have it. Maybe are you aware of the problem already ? In any case I'll leave the smallest .vgz here: 06 chani's eyes.zip (I'm aware it's useless to zip a vgz but the forum dont let me upload it otherwise)
Hi, I just took a look at your file, and it absolutely contains custom ym2612 DAC samples. There are actually very few MegaDrive games that don't use samples. And while I don't have a SAAYM or have ever used SBVGM (I'm an MSX user myself), the ym2151 is a pure FM device, it has no ability to stream samples. (On MSX we use a combination of ym2151, and MSX Turbo-R's internal PCM chip to support the ym2612.)
