A vendor has been spotted selling hacked Nintendo ROMs on Walmarts third-party marketplace. This has caught the attention of Doug Bowser, the current president of Nintendo of America. For those who dont know, ROM hacking is when a person takes the read-only elements of a game and modifies them, either to fix bugs, add translations, implement cheat capabilities, or tweak the files to create a new experience using the original as a foundation. Frequently, ROM hacks are used to make a game playable, via emulator, on a platform that it wasnt originally developed for.
