The thing with old video games, the things retroarch is translating, a lot of localizations were terrible to the point of being incomprehensible(castlevania 2) comes to mind, came with some heavy censorship(especially) with Nintendo and in some cases actually changed a bunch of the gameplay. For example, ninja gaiden 3, where the north American version cut out passwords and continues when it was localized.
