Something I kinda realized: that multi-layered font image trick I was talking about the other day: I could do something similar but probably fit multiple *four-color* layers inside of an 8bpp atlas.
And use that transparency bit trick to do basic anti aliasing 😅

the idea is that you use EMS memory pages to get four 16k banks of "VRAM", that you put sprites and tilemaps in. and then with that and an array of object attributes the renderer will render the entire 160x120 8bpp screen in one go super fast
and i'm also gonna add faux HDMA effects :3

there's record breaking storms incoming so i've been too migrainy to qbasic but i've thought real hard about what i wanna do and i've come up with
- 160x120 resolution
- 64k "vram" for tiles, sprites, object attribute memory
- everything 8bpp so i don't gotta worry about unpacking goddamn nybbles
- 160x120 resolution

might give in to the urge to qbasic today
kinda tempted to make a library used via call absolute that renders the screen via a console-like chunk of VRAM to define characters, tilemaps, and object attributes >_>

(this could extend to 8bpp as well, but it means you need 8 different 256-color palettes which is a LOT more VRAM)

Don't go anywhere! @jamieb0i.bsky.social and @sokoloshawott.bsky.social and I collabed together for the hack's intro, all of which have been ripped to be 8bpp images (the highest quality on SNES).
Check it out!

On the Amiga are you using the 8bpp back/fore buffers and blitting the fore to the screen right? - I'm not certain that 7Mhz is enough to do it but.. you might be able to do a chunky to planer ordered dither on just the updated rects.

the old one only supported an 8bpp 320x240 view (if you remember my xixit posts from my old account thats how i got those images) but this one already supports arbitrary window sizes and should soon have window resizing and support for 1bpp, 2bpp, and 4bpp images as well

Are the 1bpp, 4bpp and 8bpp versions meant to share the same base designs?

Commission work: I need 16x16 to 16x24 pixel art weather icons made. 1bpp, 4bpp, 8bpp depths. Reach out to me in DMs for details

OH right i forgot:
xpm (is there any more common format that can do this?)
- indexed color, if the palette has more than 256 colors
(it's sad that png arbitrarily limits paletted images to 8bpp. like there's nothing technically stopping you from just setting the depth to 16 in indexed mode)

Today I made a 1080p HDMI framebuffer core - the FPGA acts as an HDMI receiver, storing frames as 8bpp HPCR-encoded data and decoding them on the fly. The DDR SDRAM used is only fast enough to sustain 1080p60 with HPCR. Here you can see it switch between the raw and decoded data. Switch as HDMI src.

Alright basic blitter designed I think.

Last year I built this 23BPP framebuffer with an 8BPP backing store. It uses spatial dithering with the precision of the color channels encoded in the dither. The “decode” is edge aware smoothing. It is a reimplementation of HP Color Recovery - I will eventually release it with a full nonAI writeup.

i've once solved this mystery - a piece of polygon art focused around #blockbench 's plane polygons - i'm slowly faced up all the towel textures - though all texture images have 256 colors - i've finally drew enough textures from #graphicsgale - #segasaturn #indiedev #gamedev #lowpoly #8bpp #32bit

barely any cursing at typescript required. though i still find it weird to write in.
also i forgot this thing took color pictures!

also TIL; livearea gate can be 32 bit png..
even though the livearea graphics themselves have to be 8bpp
thats good, because the gate i just made looks awful in 8bpp :D

A memory mapped linear framebuffer with 8bpp pixels is maybe a bit easier to do that sort of thing with compared to 4bpp tiles that you have to DMA to VRAM, but yeah there's no hardware acceleration for that. Fill can maybe be used to speedup flat-shaded polygons though

I have a similar issue, but in reverse: I need to switch from memcpy'ing RGB888 frame to 8bpp palettized frame loaded as a texture on Dreamcast's GPU :P
