no wonder nobody wants to homebrew that shit

@eniko I mean, so does the NES more-or-less

@eniko NES and Game Boy use bitplanes too, and they get tons of new games. Most people aren't generating graphics at runtime except in variable-width fonts, so it doesn't really come up.

no idea how to efficiently convert 8x8 linear bytes into 8x8 planar bytes tbh

@eniko there is probably some shenanigans but most likely the "efficient" route is never doing conversion and storing them that way initially

@clarfonthey pretty sure that'd be worse because then for every pixel you want to store you'd need a bunch of reads, ORs, and writes

@eniko Amiga ?

@eniko yeah, it's garbage either way
not sure how easy it'd be to check the code for popular SNES emulators and see how they do it

@eniko It has bitplane graphics ? .. I did not know !

@eniko Everything was using bitplanes, this is why the VGA 0x13 mode was such a revolution.

@gilesgoat @eniko There was some fun stuff you could do on the Amiga with its bitplanes, like enable extra half bright mode (you set 32 colours in the palette, then it creates 32 more colours half as bright as the first 32). Then render the silhouette of a sprite into the 6th bitplane with an offset from the real sprite and it gives you a shadow cast on the background.
But yeah, very annoying if you want to do per pixel rendering.

@kojack @eniko I can't remember EXACTLY how it was, but I think the reason of "bitplane vs planar" was to conserve memory/had to do with ( slow ? ) memory access time used on the Amiga. It was an HW limit reason,I know, like the ZX Spectrum has that particular mem patter owing to limitations in the ram access times and limited circuits ( cells ) on the ULA ( yes I have 'The ZX ULA book' ) .

@eniko this is why I was happy with mode 13h before gl/dx 😂

@gilesgoat @eniko Planar is also convenient for some bit depths. Having 3 or 5 bits per pixel is annoying with bitmaps, but easy with planes.

@eniko tbh, if you want decent vga performance, you kinda need to use bitplanes there too. Imo, the only viable approach is to precalc that on level load. Dynamically converting to planar during gameplay is not going to be great.

@futboldaltonico ma certamente che lo farò! Poi andrò in giro per l'Europa con l'elefante sulla spalla e sarà bellissimo

@mos_8502 snap is particularly deranged, though. It goes out of its way to be a toxic system citizen.

@simonperry Ma comprali e fregatene. La spilletta è indisponibile, se non torna penso opterò per il peluche
-
@swelljoe Snap, flatpak, docker. Whatever they call it, it’s the same shitty idea.
-
@futboldaltonico figurati. Io mio sogno è comprare uno di quei peluche senza che nessuno mi goudichi

Why wouldn't you chew up all the disk space every day, especially when you can also destroy the SSD because lifespan of an SSD is write-limited?

@simonperry Non sapevo esistesse. Grazie
