Episode notes
Hack Week Sparked A Sega Project
- CJ used Sentry Hack Week to build a custom Sega Genesis game from scratch during a week-long company hack event.
- He chose Genesis/Mega Drive as a nostalgic challenge and to explore retro hardware development.
Demoed A Cartridge On A CRT
- CJ shows a working cartridge ROM running his game on a CRT using an EverDrive cartridge that loads binaries from an SD card.
- He demonstrated the game: a single level where you play Sentry as a pyramid-robot collecting traces.
SGDK Bridges C To Genesis Hardware
- The SGDK (Sega Genesis Dev Kit) lets you write C that compiles down to 68000 machine code, massively lowering the barrier.
- That modern tooling makes retro console development approachable for developers familiar with higher-level languages.
