This means the ROM file is corrupted, incomplete, or modified. Mini vMac checks the digital signature of the file to ensure it matches a real Macintosh chip. You will need to re-dump or re-acquire a clean, uncompressed ROM file. "Incompatible ROM image" Error If you run into errors while setting up
For many retro‑computing enthusiasts, buying an old Macintosh from sources like eBay or vintage computer marketplaces is the first step. Working Macintosh Plus units can sometimes be found for around ¥10,000 or more. Once you have the hardware, you can use CopyRoms to extract the ROM.
Requires a 128 KB ROM file. This is the most common model to emulate because it offers the best balance of software compatibility and simplicity. Macintosh 128K / 512K: Requires a 64 KB ROM file. Macintosh SE: Requires a 256 KB ROM file.

Requires a 256K or 512K ROM (used in Mini vMac Mac II emulation variants). The Legal Landscape of Macintosh ROMs
The ROM (“Read Only Memory”) contains the fundamental code that a Macintosh needs to function. The emulator requires this same information to replicate the computer’s behaviour accurately. When Mini vMac launches, it searches for a ROM image file in several locations. If it doesn’t find the ROM, it will wait for you to point it to the correct file.
The open-source nature of Mini vMac has led to interesting forks:
