  9. I've been spending more time with the Dreamcast lately, tinkering with new ideas and seeing what the hardware can do. Still working on my other games, too.
  10. I've moved the RM2K3 player from Saturn to Dreamcast. The goal is still to make ordinary RPG Maker 2003 games playable on the console. Explore RM2K3 Dreamcast →
  11. Sonic Saturn's second level, Prism Dunes, is playable now. It's a longer course with a new biome, and I'm still polishing how it plays. Explore Sonic Saturn →
  12. I've given the SAROO menu a cover carousel and starfield. My computer prepares some graphics ahead of time to keep navigation smooth on the Saturn. Explore SAROO Visual Upgrade →
  13. Signal Rider's fourth level is fully authored now. My favorite section surrounds Rin with mines and leaves one clean opening to spot and escape through. Explore Signal Rider →
  14. Sonic Saturn has a bright new roadway and floating-island backdrop. It finally looks like a place instead of a test course. Explore Sonic Saturn →
  15. Signal Rider booted and played successfully on my real Saturn through SAROO. That was a very good day. Explore Signal Rider →
