Emulations (running on Linux/Unix/Windows/macOS, utilizing SDL2) of some - mainly - 8 bit machines, including the Commodore LCD, Commodore 65, and the MEGA65 as well.
Other than the trivial task the subject tells, the default ROM-stub would be something available for the user after installing Xemu's MEGA65 emulator. Since it's often a trap for the user, what to do now, it's just stuck in a cycle (Hyppo cannot find the ROM). As users usually don't like to RTFM ;) it's a better approach to present with some ROM just barely enough to display the "what to do now" kind of description.
Later similar approach can be even used to include useful Xemu-specific tools within this ROM, other than giving an initial short guidance for the user to install some ROM.
