Super Magnetic Neo - extended prototype demo 2026-04-27.01

This is a patch for the Super Magnetic NiuNiu Promotion Disc, which normally lets you see a non-interactive preview of Super Magnetic Neo.This patch makes the demo playable - you can experience most of the game by making your way through the levels.

Apply the patch with Universal Dreamcast Patcher:

• GDI file: Super Magnetic NiuNiu Promotion Disc v1.000 (1999)(Genki)(JP).gdi
• DCP file: smn-demo-playable.dcp

The demo build is from several weeks before the final version, and has a number of differences and unfinished elements. You can see comparison screenshots in the writeup on Substack.
