i recently jailbroke my DSi with the TWiLight Menu++ and have tried to play pokemon radical red which is a rom hack of fire red. all the initial menus work rlly smoothly but as soon as i get put in my house is extremely slow and laggy. i downloaded an emerald gba and that all works fine. is this due to the rom hack being double the size and my DSi not being able to handle it or is there another reason? any help is appreciated
