SGDK is a free, open-source development kit for writing Sega Mega Drive / Genesis software in C (with optional 68000 assembly). It bundles a hardware abstraction library, resource compilation tools, and an m68k-elf GCC toolchain setup to produce ROM images.

Use cases

develop a sega genesis game in c
build a mega drive homebrew rom
learn retro console programming
compile sprites and tile resources for megadrive
make a 16-bit console game without writing assembly

When to choose

you want to write Sega Mega Drive / Genesis games in C
you need a maintained toolchain and library for 68000 homebrew development
you want resource compilation tools for sprites, tiles, and sound

When to avoid

you target other retro consoles like SNES or NES
you need a high-level modern game engine with visual tooling
you are not comfortable with C programming or low-level hardware concepts
