Neo Geo Pocket System Startup on Emulator?

[Dingo]

I've started a little pet project with the Neo Geo Pocket, and I'm looking to record some video of the system startup jingle as well as the alert that pops up when the system memory battery is dead. The problem is that the two emulators I typically use (RetroArch and NeoPop) just immediately load up the ROM. Is there an emulator out that that does allow for this stuff to be emulated? It'd be great if I could also emulate the system booting without a game so I could record some of the horoscope stuff.

MESS emulates the NGP and its color variation, and will actually make you do the system startup procedure the first time you run it.

Awesome! I just got that setup and that's exactly what I wanted. Thank you!
