I also did a Ninja Spirit comparison article 3 years ago. I tried to do the English version yesterday. Please ignore the grammer mistakes, I think it's better than Google translations. http://saintfu.myweb.hinet.net/reprogram/nspirit/p1en.htm5 pages total.
Just wanted to point out that the PCE version does have running wolves in the ending if you clear the "arcade mode"https://www.pcenginefx.com/forums/index.php?topic=6688.msg114378#msg114378Also, I really like Irem's music as well, especially Image Fight. The music isn't as rich and metallic as the arcade version but it's still unique and enjoyable.
I love the detail of these comparisons, just got done checking out the After Burner II piece. This is kinda motivating me to do the Dracxx/Rondo... detailed comparison Ive been wanting to finish, but its just so damn time consuming.
I just felt in a hole!
a lot of the detail changes in stage 1 are odd - they don't seem to be hardware constraints - they just...felt like redoing it?
They wanted the CD users to think that they were getting soooooo much more for choosing the NEC CD platform. That way CD users could brag that their version has an extra cloud or something and then HuCard users would get crazy jealous and go buy the CD unit.
arcade looks better!
