From an ethical standpoint, supporting game developers by purchasing their games ensures they can continue to produce high-quality content. For games that are no longer in print or have become rare, buying a used copy or looking into official re-releases can be a more supportive alternative.
: Always ensure you own a physical copy of the game before downloading ROMs for backup or translation purposes.
: Tools like Lunar IPS ( Floating IPS is a more modern alternative) are commonly used for applying patches to ROMs.
