Here is the arcade version of Ninja Spirit, I played thru the game to get all these songs, & apparently there is one song that was in the Turbo Grafx version, that isn't in the arcade version, unless I somehow missed it, which I don't see being possible.

I'm so used to the Turbo version, it'll sound a little weird to me, but great job, nonetheless.
By any chance would you happen to have the Arcade version of Splatterhouse as well as the Turbo version?
That seems to be hard to find as well as the Arcade of Kidniki and Rygar. Any leads would help greatly..

Let's see, there's 3 different Rygar soundtracks listed at the Galbadia Hotel, not sure if any of them is the arcade version. I'd personally love to have the ost to the Lynx version. Haven't seen Kid Niki anywhere. I don't have either Splatterhouse yet, but I suspect it shouldn't be too hard to do either of them. Although, the arcade version might be hard, since I'd have to play thru the game to get the music, & I don't know right now if there's any songs that would be hard to record due to other noises going on in the game during the music.
