How would you do volume changes as register writes if the PCM data itself is written as a volume change on channel 0? Ah yes, you're right... I forgot that in the case of the SN76489, the samples ARE the volume. Yes, you'd need a translation table in between, which is not there. One way to support …

Well, that's my point... you can't capture such VGMs directly from an emulator. Not that it would matter much in this case, since there are only 4 games that I know of, which are the aforementioned ones. I'm pretty sure the player does support volume changes though. Not sure if they're actually used …

Implementing stream commands would complete the VGM format implementation and is the more elegant solution, elegant as in being entirely software-based. :) But can you reliably capture VGMs that way? I mean, Rob Hubbard's music system is basically a single-channel mod player, and it uses all sorts …

It seems that SBVGM does not yet support VGM stream commands. They can be very useful for some songs; I have attached one of them. It's the title screen music from the 1989 Electronic Arts game "688 Attack Sub", played on the Tandy 1000. The game plays PCM samples by manipulating the volume …

Not sure what 'clobbers' means in your world, but the RX480 is slower than a 970 in various cases: https://www.anandtech.com/show/10446/the-amd-radeon-rx-480-preview/4 And a 970 is a few years old. Look at how much faster the 1070 is in that review, for example. And that's basically the replacement …

XBox One X is basically a fatter Polaris (40 CU@1175Mhz vs 32 CU@1120MHz of the RX 480/580). I was talking about the regular XB1 and PS4 there though. Seeing that a RX480 already clobbers a GTX 970 Not sure what 'clobbers' means in your world, but the RX480 is slower than a 970 in various cases: …

That is only half of the truth. The level of programming that PS4 and Xbox One developer do makes the GPU and CPU perform much better (considerably so) than if the same pieces of HW were say put in a Dell and you would run a normal DX12 game. Yes, but firstly, programming environments of consoles …

Did the PC already surpassed as usual the modern consoles (also considering the newer more powerful console versions PS4 Pro...) These consoles were never at the level of the more high-end gaming PCs to begin with (even single-GPU ones), so there was no need to 'surpass' them. Their CPU is two low- …

The one I found even more interesting was the Trident FPGA card in that article: https://www.imgtec.com/wp-content/uploads/2017/08/trident-front-med-1024x356.jpg I recall a discussion about some code in the drivers somewhere that indicated ISA support. I suppose this prototype explains that. There …

Is there any noticable performance difference between PCX1 and PCX2? Are there games which only work on one or the other? I have a PCX1 and not many PowerVR games, but not a PCX2 and have always wondered what I'm missing :( I believe the main differences are that PCX1 has no bilinear filtering, and …

Yes, the Game Blaster/Creative Music System (two names for basically the same card, yay marketing) is the spiritual predecessor of the Sound Blaster, but is in no way compatible with the Sound Blaster. The Sound Blaster is based on the AdLib card with a Yamaha OPL2 synthesizer, instead of the two …

At the moment, the most I can tell is that the volume control signaling is handled through pins 1, 14, 16, 17, and pulling all those pins high drives the on-board amp to full output. Those 4 pins are the only other 4 output pins on a parallel port, aside from the 8 data lines. My guess is that one …

So, at what point (as in a year) can one deem 2d graphics cards as what you call 'modern'? Which I view as a fully functional card for 2d windows95 DirectDraw games? Is it 'mid-nineties pci graphics cards'? That depends on what you consider 'fully functional'... There were various different pixel …

I was comparing apples to oranges. 'Software rendering' to me meant what you see in quake2 or unreal. Rendering done by the cpu. As mentioned, there are two ways of doing 'software rendering' that way: 1) Using DirectDraw simply to access the VRAM of the graphics card, and the built-in renderer of …

It depends on what you mean by 'software rendering'. DirectDraw supports certain hardware-accelerated operations, such as (stretched) blit, pageflipping and such. But it's all 2d-oriented. There are no 3d drawing primitives in DirectDraw. Direct3D started as an extension to DirectDraw, so depending …

Interesting... I would have expected the PIII and Athlon to be more or less evenly matched, and the P4 to be less efficient. But it looks like the PIII is in a class of its own in terms of efficiency, and the P4 Northwood is very close to the most efficient Athlons. It's only the Willamette that's …
