Hi guys I just bought the megaflashrom scc+cd and I had no idea how to setup. I watched the https://youtu.be/2XHbSgKTwMU video and the guy said to put all the os and programs to a sd card and reset, press the arrow up and then press f3. I did that and transferred all my programs to the sd. After that I saved a rom in the same cartridge and reset it. The game didn't load and all I get now is a black screen. I know I did something stupid trying to setup it myself without knowing how the cartridge works. I sent an email to Manuel and I hope him or one of you guys can help me to restore my cartridge. I could kick myself for doing something so stupid! after waiting a whole week for this cartridge. I hope I can make my cartridge work again.

Not to worry, it’s just the ROM that isn’t working that keeps locking up. Just boot with the up arrow again, you will be in what is called the MFR’s recovery. Press F1 to erase the ROM and the MFR will boot from SD card into Nextor.

The cartridge is fully configured out of the box. You do not need to install anything to use it. Just format the card and copy ROMs and DSk in it.

F3 option in recovery erases the ROM disk, the preinstalled A: drive with Nextor, MultiMente and other tools. So from now on, MultiMente or Nextor will not boot anymore.

You need to restore the ROM disk:
- Download: https://msxcartridgeshop.com/bin/files.zip
- Unpack it and copy the files on the root of your SD card
- Put the card in the cartridge and switch on your computer
- Nextor (operative system) should boot and you will get a "A>" prompt
- Type in the command line:
OPFXSD ROMDISK.DSK /id
and press RETURN

That will reinstall ROM Disk (drive A: )
