Add support for additional Sharp MZ computer systems to the LaunchBox Games Database.
Currently, the database includes the Sharp MZ-2500, but several earlier systems from the MZ family are missing, including the Sharp MZ-700, MZ-1200 and MZ-1500. A growing amount of software for these systems has been preserved and made available, making the lack of database support increasingly noticeable for users cataloguing these libraries.
Before adding them individually, we should investigate the compatibility between these systems and the wider MZ family to determine whether they should be represented as separate platforms or grouped under a broader Sharp MZ platform.
Requirements
Investigate the MZ-700, MZ-1200 and MZ-1500 and their compatibility with other Sharp MZ systems
Determine whether each meets our criteria for a distinct platform
Consider whether closely compatible systems should instead be grouped into a single Sharp MZ platform
Ensure games currently missing from the database, including Sharp MZ versions of titles such as Pac-Man, can be correctly represented
Keep the existing Sharp MZ-2500 platform separate if it represents a distinct hardware and software ecosystem
