Emulation Inception

[CapitanClassic]

What is the deepest level of emulation within emulation you have attempted?

 

For example, you could play Atari 2600 games, within a Gameboy Advance emulator, within a Windows XP emulator, within a MacOS. (4 levels)

There was a joke Amiga emulator for the Atari ST, and if you double clicked the Atari ST emulator which was in the Amiga emulator, it read "Running an emulator within an emulator? This is getting pretty weird. I have to put a stop to this." At this point you'd click OK, then get an amiga guru meditation. Funny stuff.

There's no easy to use Odyssey 2 emulator on mobile. So I've put the DOS O2EM emulator inside a DOS emulator so I could play Pick Axe Pete on the road, badly, with virtual controls. I have done this fairly recently.

 

Android or iOS > DOSbox Turbo > O2EM

 

Only 3 levels, but still a major pain the butt and mind-bogglingly stupid. What do I win?
