I've read from some programmers that snes has an amount of memory for sprites, and an amount of memory for backgrounds, so it is preselected. Ah. That information may pertain more towards game-specific memory budgets, then - if you were doing modifications to an existing game like Super Mario World...

Hmm, I'm not sure where you ever got 45KB from. The total RAM available for the PPU is 64KB in size, and all background, sprite, and tile data can be addressed in that space without any restriction. I've read from some programmers that snes has an amount of memory for sprites, and an amount of memo...

They would have needed working prototypes of the hardware at least 6 months before final devkits. Here is a link from nintendolife (i didn't read yet).

@Señor Ventura What are you trying to say? Both SNES images take the same amount of memory in VRAM; 56KB excluding the tilemap. Backgrounds can use 1024 unique tiles, which for an 8bpp background, is the entire 64KB of VRAM. But the ppu1 don't give more than 45KB for backgrounds, so, i don't get wh...

The SNES ones are the two on the bottom; the bottom left is with 8 channel HDMA, the one in the bottom right is without. Fantastic job by the way; it looks closer to the 15bpp version for the most part. The shadow of the face is the only thing that looks noticeably poor. With the 8bpp version, I'd ...

The 15bpp images are only provided for reference/comparison, as per lidnariq's request.

So, the two of the snes are the two of the right, right?.

That 15bpp are really possible in snes?, How many KB's occupies?.

Wasn't the restriction to 2.68MHz because of the slow ROM chips of the day + the 8-bit data bus? Yes, presumably the WRAM forces the DMA to adapt its frequency to 2,68mhz, i don't know if the DMA actually works at 3,58mhz of stock. A 16-bit data bus is needed, but that doesn't seem possible with a ...

There is the small matter that the SFX didn't exist when the SNES was made. The fact is was made in the UK by Argonaut. I've read that it was near to be real simultaneously during the fabricantion of the american snes. Does the SNES make use of the phi1 half of the clock cycle to bus share? Here yo...

I found this newspaper article from 1984 and it says the 68000 was only $15. If that's the case how cheap was it in 1990, and how much money did Nintendo really save by using a custom 65816? https://www.nytimes.com/1984/06/29/business/motorola-s-powerful-new-chip.html Not only in matters of money, ...

Greetings. Lately have been rounding over my head some questions about the snes and its potentially spectrum of possibilities in terms of hardware. The option of an different cpu than the 65816 is discarded cause it always been plannified an custom WDC, but the question is, What kind of solutions wo...

This is hypothetical and thus not useful, but the sad thing is, if the SNES had 128KB of VRAM as originally intended, the S-PPU could have been made to support something like a 16bpp bitmap mode, as it has just enough graphics bandwidth. (Although you'd only have 8KB for sprites, assuming the bitma...

...that's not a good excuse. Remember, SNES pixels aren't square; the image stretches to fill (approximately) a standard 4:3 TV screen. Neo Geo pixels aren't quite square either, but they're closer (actually, the display area was 320 wide, but most games didn't use the full width because the output...
