I own a Turbo Duo and a PCFX.
I have over 120 games for those systems.
I set asside my Duo in storage mainly because the sytem is dying, and I emulate mainly because of convenience. With going to school fulltime, raising 3 kids and being Married to the love of my life, I can only set aside a few hours a week to gaming, and its much more convenient to double click on my PC Engine Icon on my Desktop after completing a 4 hour COBOL(yuck!) program and plug away a few minutes on Keith Courage, than to try and set up my TurboDuo.
Personally yes, i do prefer the feel and style that playing the original Hardware that the games were intended to be played on, but I also think emulation is amazing and is a great alternative to those that wish to 'try it out' or are having hardware issues.
I am going to be picking up another DUO soon, at the very least by TurboFest2007(cheap plug). But this wil be MY THIRD TurboDuo, as the first Turbo I've owned both stopped reading disks, and the second is on its way, The CD spins but I get no sound.
Just thought I would shed some light on my comments from earlier~
about Storing Systems and all hail emulation or something like that....
