The term identifies a specific modified version of a popular monster-collecting and battling role-playing game, accessible through the acquisition of a read-only memory (ROM) file. This action typically involves obtaining the game data from unofficial sources. Such altered game versions offer enhanced difficulty, rebalanced gameplay mechanics, and expanded content compared to the original. As an illustration, the modified game version might include all creatures from later entries in the series, or feature dramatically increased opponent strength, demanding new strategies from the player.
Availability of such modified game versions offers a distinct gaming experience for established players seeking increased challenge. These revisions often cater to a community that has extensively mastered the original game, providing new goals and renewed interest. Historically, these modified experiences emerged from a desire to overcome the perceived limitations or predictability of the standard game. The distribution model, relying on external file acquisition, bypasses official channels and established digital marketplaces.
