I liked that game, too and one time in my live I played it a lot. Nowadays I’m into SSV Special and SS2 again, but I still know a bit about the game. Oh and Genjuro was a beast, who could do even a 100% combo in special situations … (if you want I tell ya)
I’ll try to give you a bit help about the CD combosystem and not the normaly stuff (simple Genjuro example: close s.B, qcf+A, qcf+A, qcf+A). Anyway, SS Games were not so combo happy except for SSIV. First of you need to know, that a hard slash does often the same or bigger amount of damage then a standart CD 14 hit combo (f+A, A, B, B, C, C, A, B, C, C, C, C, C). The good thing about everyones normal 14 hit is, the powerbar is maxed out afterwards. The bad thing is, that you can be punished pretty easy, if the CD is blocked and even if you make the first hits the combos can still be guarded when you are not fast enough. Just to let you know, with a full powerbar some special moves get stronger and you get also access to your super. Back to the CD combos … You have furthermore the possibility to cancel the standart combos with special Moves, supers and the special abilitys gained through rage activation. A more advanced example here. You are a raged Genjuro in your final round and hope to make a comeback, because you are nearly dead. You landed a lucky CD Slash and go all out now. You do f +A, A, B, B, C, C, A, B, C, C, C, b, f, d+A+B/or do Fatal Slash (B+C+D) and the opponent loses his weapon, plus he gets a lot of damage. But that is not what we want, we want more damage and hits! So we do now f+A, A, B, B, C, C, A, B, C, C, C, A+B+C (this is a mini auto combo) and cancel this into another f +A, A, B, B, C, C, A, B, C, C, C, A+B+C and do again f +A, A, B, B, C, C, A, B, C, C, C, but since our rage meter is nearly empty now, we do the Fatal Slash or super like in the first example! If the rage is already empty do a good special Move with Genjuro, qcf+A series for example or even more bad stuff (which leads to the 100% combo;)).When you are fast you can do this on everyone without a chance to miss. I hope my few examples helped a bit and get you into the right way for doing combos in SSIV.
