Is anyone else having issues with copies of this. I have tried 3 or 4 copies and they all just go to a black screen and do not start. Has anyone had any luck getting it to start?
If you're on a flash cart; either upgrade it to the latest firmware or add a secondary firmware to run the rom from.
I have acekard 2.1 or 2.i but the link doesnt go anywhere to update it. it seems its updated to version 2.3. is Marvel containing anti piracy measures
Acekard is dead. So too it's secondary firmware 'AKAIO'. There's no anti piracy protection in the rom. Your choice now is to either play via emulator such as DeSmuMe or No$Gba, or buy newer cartridge that still receive official updates from it's producer or at least one that is supported by a secondary firmware such as YSMENU or WOOD.
Lucky you since this rom doesn't contain AP. However, in the long run do consider buying new cart since newer rom often has AP in it which AKAIO might not be able to overcome.
