  1. All the photos on the site show a loose ROM board stuck into the MSX cartridge slot, which seems kind of iffy to me. If I bought this thing, would I actually be getting a cartridge casing around that, or would you just be shipping me a loose board?

    Also, just to double-check, would this just be plug-and-play? Does anyone know? Like, could I put the double RAM cartridge into my 64kb Japanese MSX2+ machine, put in a disk loaded with MSX-DOS and a bunch of roms, and play those roms with execrom even if they're 512kb games, without having to do any additional fiddling around?

    Really tempted to buy one of these, but I'm a total idiot when it comes to real nitty-gritty technical stuff, so the more user-friendly this is, the more likely I am to get my money's worth out of it.

    If you guys can update with an answer on this, it would be appreciated. Thanks!

    1. Hi Thomas.
      The cartridge will have a box.
      Yes, DoubleRAM is plug&play. Just select what you want: MEGARAM or MEMORY MAPPER.
      You can use EXEROM to load MEGAROM converted games into DoubleRAM (in Megaram mode) and play the games.
      Don't worry, we will supply instructions. ;-)
