i'm done making a 8x8 red-to-yellow gradient wallpaper - look's cool right - hoped you all liked it - #pixelart #segasaturn #gamegear #8bit #32bit #4bpp #bubblegum16 #graphicsgale

The nibnib image format is a new, lightweight compression method designed for extreme decompression speed on microcontrollers like the RP2350. By using a delta-based palette and decoding two pixels at once, it achieves high performance at 4bpp.

i'm done making a red 8x8 zapper - hoping this would be a experiment - though now it looks better than my last #pixelart i've made - #4bpp #segasaturn #gamegear #bubblegum16 #8bit #32bit

i've finished making these tile assets - but they're kind of actually good - and for my guesses - they're polished - it's a good thing i've actually made this on #tic80 first on my tablet before bringing it over to #graphicsgale for my #gamegear #pixelart - #4bpp #8bit #gamedev #indiedev

Mode 1's BG3 is the 2bpp layer, so its tiles take half the VRAM of the 4bpp planes. Which bought more of the 60 FPS on Square Brothers: moving art onto that plane, or cutting the number of actors on screen?

After all these years I still haven't figured out the logic behind the colour bits encoding in the 2bpp and 4bpp modes. I may very well have missed a specific MODE5 trick though

all right - disappearing for long periods of time is just part of my personality, so anyway for my appearance - i've have finished this spinning cd(at 32x32 pixels) - very cool - and more detailed - than my past art - #segasaturn #pixelart #sprite #dotpict #4bpp #32bit - i hope you liked this

I also told him that I will be adding ALT1+MERGE to do original GSU1/2 MERGE while in 4bpp FX3 mode, which will DRAMATICALLY speed up texture mapping in StarFox 2 FX3, which is the one we're really wanting to work towards.
Sunlit had to program GSU1/2 merge MANUALLY into SNES land because of 4bpp.

due to the gamemode I'm using I'm restricted to 4bpp, but the video itself will be black and white, which is wasteful of course but also means i only need to modify a single bitplane for a given pixel on a given frame

Rocket Slime stores graphics + data in banks like:
Graphics
Frames
Animations
Graphics just contain the actual graphics, standard 4bpp tiled NDS graphics.
Frames contain OAM attributes which are used to build sprites made of multiple OAM objects
Animation contains anim data (timings, etc)

the colors suck (it's limited to 4bpp) but that actually (potentially) opens up a new world of pixel-perfect EGA ports (or intelligently scaled, with more pixels to work with)

There's a trick I've always wanted to try w/PSX homebrew programming where I think it would theoretically be possible to pack four single-color "layers" in a single 4bpp texture, using four different palettes to select which layer is visible.

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?
