Final spec:

how to use:
you need download the last ultra menu APP, then specify the MD bios file to "NEOSEGA4.BIN" and format the neo2 myth flash cart, after it then add the "NEOSEGA4_Return-Menu.SMS" rom to the first space in the rom list, and add more roms to it and burn.

about the cheat code, for example the "1364 - R-Type.SMS" rom, you just need enter the cheat code "CED8FF" in the menu then start to run game, you can use the switch to enter the ghost plan mode in any time, and when it active the LED will turn to RED.
