My Minecraft-inspired game is now ported to the SEGA Dreamcast, a retro console from 1998. The Dreamcast features a 200 MHz in-order execution CPU, 16 MB of RAM, and a 16 KB direct-mapped data cache. To give you an idea of the challenges involved in this port, all vertex transformations, clipping, and lighting are managed by the CPU, as the Dreamcast's GPU functions only as a triangle rasterizer. Based on my benchmarks, the Dreamcast is >4x slower than the Gamecube. These constraints offer exciting technical challenges.
