"LHX Attack Chopper was an 1990 helicopter combat flight simulator, developed and published by Electronic Arts. The game is most notable for being the only - or at least one of very few - to include the V-22 Osprey hybrid aircraft. There were several recordings of the LHX intro sequence and gameplay on youtube already, but all of the ones I found were using the PC Speaker sound, even though the game supported the superior Adlib sound card (and possibly even the Roland MT-32, but I have not tested that). This is the intro sequence. I think I let the music loop once, but I'm not sure. Recorded in Dosbox 0.73, so the emulation is not 100% perfect, but actually really close."
