This game is made through the RPG Maker XP software, so there is no ROM hacking involved. The emulators that are used to play Pokemon games are made to emulate Nintendo's handheld's systems. Since this game is made on a software for personal computers rather than the aforementioned systems, then you can't use an emulator in the traditional sense to play this. If you wish to play it on a mobile device then I believe you're out of luck, since last time I checked no software that allows the user to run RMXP games on mobile systems exists.
