scratch VS SGDK

pbmview, an image viewer (windows subsystem).

For comparison (for those following along): https://github.com/skeeto/scratch/blob/master/parsers/qoi.c https://github.com/skeeto/scratch/blob/master/parsers/ini.c

Another option I learned a couple years ago is embedding a UTF-8 manifest ([details])[https://github.com/skeeto/scratch/tree/master/libwinsane]. Also put the console in UTF-8 mode (SetConsoleOutputCP(CP_UTF8)), and you're done. Works on Windows 10 and later. This covers everything: argv is UTF-8 and fopen accepts UTF-8 paths. (This is exactly how CRTs should have worked all along.)

I was thinking more about this and I realized it's quite easy to do it in arbitrary precision, so here's my take: https://github.com/skeeto/scratch/blob/master/misc/bswap.c

As was linked from my QOI article, here's my full decoder with comments: qoi.c. Each pixel decodes to a 32-bit integer, ABGR. That corresponds to SDL's SDL_PIXELFORMAT_ABGR8888. SDL_UpdateTexture copies that data into the texture's internal storage, and font is no longer needed. (In a real program I'd allocate it in a scratch arena, reset after initialization.)

A recent, interesting experience with function+context allocation: For more than a decade, Windows accidentally exposed part of zlib in a public DLL, and (overly-)clever applications can exploit this as a "system zlib." Though it doesn't export the "end" functions, so cleanup seems impossible. However, custom allocation works, so doesn't matter. I plugged it into an arena.

It might have needed two at one point. I see both mentioned in a few places, but the wiki appears to say you need the full path. https://github.com/Stephane-D/SGDK/wiki/SGDK-Usage

P.S. The plan down the line is to at some point add sprites to it and port it to the Sega Genesis using SGDK so it would no longer be a text adventure game. However for now I'm having fun practicing my C skills with this and hopefully will have a cool project for my portfolio.

Examples: - Someone I know created machine-optimized library in c and asm to accelerate compression, erasure coding, and encryption on Intel Xeon CPUs (https://github.com/intel/isa-l) which runs those ops WAY faster than the standard linux libraries. - My friend is making a retro SEGA genesis game using a C and asm dev kit (https://github.com/Stephane-D/SGDK)

If you are specifically looking into the Genesis you should look into SGDK, the sega development toolkit https://github.com/Stephane-D/SGDK.

SGDK may be one reason. Nothing comparable on the SNES side.
