Last year i got my replacements for flash carts.Bought a "everdrive X5 for the genesis and a SD2SNES" for my super famicom,both flash carts have worked for me so well at this point.Though i haven't look into hacks etc so far for any game at this point.I still need a flash cart for my famicom av with the pro everdrive N8 out now maybe some time this year i'll buy one.For mods i don't have the skills often i'll have others i know that will do the mods for me.
