Arnold features emulation for the five different models of Amstrad CPC - namely the CPC464, CPC664, CPC6128, 464 Plus, and 6128 Plus. Arnold features extremely precise emulation, allowing complicated demos to run correctly in emulation. To that end, it runs in 16-bit colour so that the palette can remain 100% accurate. (The CPC+ hardware could support more than 256 different colours on screen at a time).
