Re: Capabilities of various VDPs at parallax effects

The SNES using of 512 pixel mode doesn't blend well though. The composite artifacts, at least in NTSC.. leaves a lot of garbage artifacts (you can see it when SNES games using interleaved pixels for pseudo transparency via 512px mode over composite - it looks horrible). PCE doesn't have this issue; ...

Re: Capabilities of various VDPs at parallax effects

I don't think anyone has made a decent converter for images using S/H.. at least not publicly. That's true :( I came across this one - Bitmap MD from Markey Jester https://www.youtube.com/watch?v=BcRDfi2XVMk But it's not show full MD/Gen (color wise) potential. At least I can't repeat Toy Story's c...

Re: Capabilities of various VDPs at parallax effects

https://www.youtube.com/watch?v=1iq8nQ2Bd80 ^ This was dead simple to do. There's no crazy code or optimizations. It's just a simple concept and execution. Lot of cpu resource left over too in the frame. You know, I just realised something. Having mentioned previously that your parallax demos, the ...

Re: Regarding Street Fighter II: Special Champion Edition . . .

The HUD is not sprites (well, not all of it. The names and the timer value are): https://i.ibb.co/BwbYNvc/Screenshot-2023-06-18-235032.png The dark red and green are BG layers (priorities). And the dark purple-pink are sprites. You can see that just the top left and right pieces are sprites on the f...

Re: Regarding Street Fighter II: Special Champion Edition . . .

It is sprites, even for Vega's area. Play the game in Blastem and enable the priority layer window, and you'll see how they did it. It's used for a lot of stages around the top of the status bar.

Re: Regarding the 480i mode on Genesis. . . .

I wouldn't call it "tearing" as that implies something else. It's called "combing" because the out of sync updates of the fields are every other line.,, it looks like the teeth of a comb.

Re: Capabilities of various VDPs at parallax effects

And, you're saying that using the two backgrounds with the single 256-colour palette [chosen from that 32,768 master palette] in SNES' Mode 3 or 4, with one background in 8bpp and the other in 4bpp or 2bpp (depends on the mode), plus some colour math and the like, would definitely be better than tr...

Re: Capabilities of various VDPs at parallax effects

Yeah, this isn't exploiting chroma <--> luma interference like on many other "hi color" demos for multiple systems (Apple 2, CoCo 3, MD, etc). The Genesis/MD, for NTSC, gets blended colors simply because the Luma signal is almost twice the chroma signal, and it's difficult to separate (there's no al...

Re: Capabilities of various VDPs at parallax effects

Is there no "other" section on the forums? Oh well, shameless plug for my "hi color demo"... a wip demonstration, for PCE: https://www.youtube.com/watch?v=FjYw55qn8Rw Via snes: Direct color mode is okay, it has limitations of being stuck to a small overall color palette. I think mode 4 with 8bbp til...

Re: Capabilities of various VDPs at parallax effects

I presume it's because the Genesis and PCE are similar in how they do their graphics: they have a 16 color playfield (two for the Genny) and 16 color sprites. They just have lots of palettes to allow different sets of 16 colors for different sprites compared to the layers. In the SNES 256 color mod...

Re: Capabilities of various VDPs at parallax effects

Those "benchmark" videos just demonstrate that while the person knows how to program, he knows very little about hardware. Understanding the processors and related chips at a hardware level is necessary to get the most out of a system. Many games don't need the most, so you don't need to understand...

Re: Understanding the VDP's scrolling capabilities.

Why are you necroposting a 12 year old thread?!

And those last two videos are gamemaker mock ups - not snes code or demo or rom. Also, why are you even here inceptional?
