Top 20 Dreamcast Games to Play on nullDC

nullDC vs Reicast — which is right for you?

nullDC — older Windows-focused emulator, simple setup, good compatibility for many Dreamcast games, lightweight but no recent active development. Best if you want a straightforward Windows PC experience and don’t need modern features.
Reicast — descendant of nullDC with wider platform support (Windows, Linux, Android), better ongoing community forks (e.g., Flycast) and more modern features. Best if you want cross-platform use, active improvements, or mobile support.

Platforms: nullDC — Windows only. Reicast — Windows, Linux, Android (and forks extend to more platforms).
Active development: nullDC — largely inactive/legacy. Reicast — more recent community activity and forks (Flycast) continue development.
Compatibility: both handle many commercial games; Reicast/Flycast generally have broader, more up-to-date compatibility and fixes.
Features: Reicast/Flycast add modern conveniences (texture dumping, widescreen hacks, upscaling, mobile-friendly UI). nullDC is simpler and lighter.
Performance/Tuning: nullDC is lightweight on PC; Reicast/Flycast offer more options (CPU/GPU tweaks, upscaling, arcade boards like Naomi/Atomiswave via forks).
Ease of use: nullDC is straightforward on Windows; Reicast has more settings but better guides and community support.

Choose nullDC if: you only use Windows, prefer minimal setup, and want a lighter legacy emulator.
Choose Reicast (or better, its modern fork Flycast) if: you want cross-platform support, active updates, modern features (upscaling, texture support), or mobile play.

If you want, I can give download links and a short setup guide for either option.
