: You can move or delete any single game file without breaking others. In "Split" sets, deleting a "parent" game will make all its "clone" versions (like a Japanese version of a US game) unplayable.

Accessing and using ROM sets with MAME 2003+ requires an understanding of the legal and technical aspects of emulation. While MAME and related communities provide guidance on obtaining ROMs, users must ensure they comply with copyright laws and only use ROMs for which they have the rights to use.
