SGDK VS gb-studio

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

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.

GB-Studio (MIT/C) https://github.com/chrismaltby/gb-studio

I doubt it was intentional. They hired a studio to make a retro style game and they probably just happened to hire one specializing in gb development. There's a lot of good tools now like https://www.gbstudio.dev/

👾 Software - GB Studio. I spent a large part of my childhood playing Tetris and Micro Machines on my Gameboy. Now anyone can create Gameboy games with a drag-and-drop editor.

Very cool! Maybe you can make a pixel art style portfolio of your work that runs on a GB cart and a rom to share around? Do you know about GBStudio?

No, it's an actual game boy game built using GB Studio, that's the point, that it's compatible with any device capable of running GB games, including original hardware! :)

It actually does interpret bytecode, you can see the opcode definitions here https://github.com/chrismaltby/gb-studio/blob/1f995a976bd3aa...

The trick is that a lot of the heavier stuff is implemented in assembly and this is mostly used for lighting scripting (from what I understand).

Me when gameboy studio exists: https://www.gbstudio.dev/

If you ever want to just play around with gameboy stuff, GB Studio is much simpler, but only supports building certain types of games, since it's a no-coding kind of thing.
