No, I wasn't. It seems quite dumb to me. I'm not going play Ys in a cab and if I wanted any of the arcade games that were ported to PCE I'd play an arcade ROM or a much better port.
The conversion systems that were made back in the day make at least a little sense since they were designed to put in actual arcades. At home it just seems like an inconvenience. Now you're playing vert shooters butchered into 4:3. Now your audio is limited by whatever junk speakers are in the cab.
I'm not saying games would be unfun or unplayable or anything, I just don't see the point in spending time and money on something like this.
I guess some of the original fighters and shooters might be nice to have, Flash Hiders, GoT....
