# PC Engine/TurboGrafx-16

|
|
a console from NEC that, depending on a region:
|
|
attempted to enter the fierce battle between Nintendo and Sega, but because its capabilities are a mix of third and fourth generation, it failed to last long. (US and Europe)
|
|
was Nintendo's most fearsome rival, completely defeating Sega Mega Drive and defending itself against Super Famicom (Japan)
|
|
|
|
it has 6 wavetable channels and the last two ones also double as noise channels.
|
|
furthermore, it has some PCM and LFO!
