Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

FC8 – Faster 68K Decompression (2016)
I'm working on a game for Amiga (another 68k-based platform) and settled on ZX0 to decompress assets on the fly: https://github.com/einar-saukas/ZX0
I was originally using LZ4, but I switched to ZX0 after learning that it can do in-place decompression, which means I don't have to allocate separate memory for the compressed data. I'm very happy with the compression ratio, and decompression of large assets (~48kb) only takes a few frames on a 7MHz 68000.
Also of note is LZ4W, included in Sega Genesis Dev Kit (and discussed in the comments section of OP's article), a variant of LZ4 that only uses word-aligned operations. That makes it much faster on the 68000, which can struggle to efficiently handle 8-bit data. More info here: https://github.com/Stephane-D/SGDK/blob/master/bin/lz4w.txt

Problem with compiling
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

Best way to create a map with enemy characters using C?
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.

At least college isn't making me learn Objective-C.
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)

What is it called when you make a whole new game and put it on a old console like NES Atari genesis etc
If you are specifically looking into the Genesis you should look into SGDK, the sega development toolkit https://github.com/Stephane-D/SGDK.

- Dear developers and hardware engineers of reddit, It is possible to develop new games for old consoles? Like the SNES or DS for instance. If it is indeed possible, what tools would be required?

Difference in accuracy when compiling in windows and linux
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 made this small program in C :)
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

Beside SDL, is there an easier way to just show a custom rectangle with text, cross-platform?
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.)

GitHub - pmkenned/pmk_string: A simple string library in C
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.
