To start off with, I have a 512Megabit NeoFlash cartridge, a 128Megabyte SD card, an MK2 and an MK3. I have a Version 2 firmware DS flashed with FlashMe Version 7 capable of booting directly to the MK2 menu.
I've followed the following instructions:
1.Flash the menu to your Flash cart
2.Put the menu on your SD card
3.Turn your ds on with SD card and Flash cart inserted
4.Go to SD menu
5.Highlight menu nds file and choose flash to menu option
Here's the problem;
My MK2 works fine, the menu flashing procedure went perfectly. However recently my MK3 messed up when I turned off my DS, it was no longer able to save / load from the inbuilt save buffer. I've tried following the instructions above with my MK3 and it freezes when trying to flash to the menu space, it also freezes when I try to format the menu space. It also freezes when I try to boot a game and select the 'Erase MK2 Save' option.
I can use my MK2 fine but I'd prefer to use my MK3 simply out of convinience, does anyone have an answer for what could be wrong with my MK3? Should I just throw it out as junk?
