I actually owns a crappy Windows tablet, which has an Intel Atom Z3735F processor, 2GB of RAM and 32GB of eMMC storage.

The hardware configurion is actually capable to run Lunar Magic and other SMW Hacking utilitys smoothly. However, It's painful to make a level with it, since Lunar Magic is not really optimized for touch screens. So, I have to add mouse and keyboard, but it's lose the point of why using a tablet instead of a full PC.

Maybe FuSoYa will release some version of Lunar Magic that optimized for touch screen controlling, but for now, I think it's better to create a SMW Hack with keyboard/mouse on a PC or Windows Laptop.
