Nice. You've been a great help. Thank you!

The X series can do the full 128k save, so yeah it's in tact. No need for dupe roms.

Thanks for the reply. Is the file structure intact with x3/x5, or would I need to save a separate copy of the rom on the Everdrive for every save file? I suppose it doesn't matter too much, really.

Can confirm it works on Everdrive X3. LSDJ does NOT work on the original Everdrive GB (no longer sold to my knowledge. I would recommend getting the x5 or x7 for LSDJ though, x3 makes you click a button after you save to actually write the save file. If you forget to do that after saving, you will lose your save. I think x7 only adds RTC support that we don't care about for LSDJ. Looks like the x5 is the sweet spot for LSDJ.

I'm seeing conflicting information online. Am I still relegated to the EMS carts, or does the Everdrive GB (X7, I assume) support LSDJ and it's file structure, etc?
