Hi, I have recently bought a 20th Anniversary Famicom Gameboy Micro and the Classic NES - Super Mario Bros. But there doesn't seem to be a save feature for the game. I know what Super Mario Bros. on the NES can't save but the Classic NES Series is a series of NES roms and emulators on GBA carts. If you press L and R, the emulator menu pops up. On the menu there is a save button but when I press it, it seems to have saved but when I turn the system back on, the save state is wiped off. I have no way of finishing the game game because of this. Please help.
