Yup, same! Can wholeheartedly recommend it for those who want something between emulation and real hardware.

The Amiga core is fun, AGA, 2 MB chip, 384 MB fast. It supports hard disk images, so you can do a hard disk based Workbench installation and load games and demos practically instantly (and safely exit to Workbench) using WHDLoad.

Arcade cores are fun as well. Just like in childhood, but less hungry for quarters. :) Recently played with arcade Gauntlet core a bit for example.
