Hacking EZIV doesn't require flashing to NOR and PSRAM and all that right?

[Link5084]

So it's simply just drag and drop GBA ROMS onto the miniSD for the EZ Flash IV? How does it all work?

GBA roms need to be patched.
There are several applications but I suggest you go with EZ4Client for now:

They will automatically copy from the miniSD to the PSRAM. Should they be bigger than 16 megabytes they will ask to copy to the NOR, you can also copy to the NOR on request.
