A different emulator may suit you better if you want Android support, broader arcade or vintage-system coverage, multiplayer tools, or to avoid supplying BIOS files. nullDC does not list Android, requires a Dreamcast BIOS, and its historical netplay server is limited to beta 1. When switching, weigh the systems and platforms you need against the alternative’s setup requirements and focus: some emphasize arcade preservation, development tools, or online play rather than Dreamcast emulation alone. Build-channel stability and any paid upgrade may also matter, depending on the product.
