First of all i have to say that I am very confused about DDP DOJ.
I watched this huge scoring thread about DOJ and a video from sapz(dude) on youtube and this game is without doubt truly beautiful. I'm quite new to the shmup genre so I don't get the mechanics in every detail yet but i have an idea how the game works. I just finished 1cc'ing Daifukkatsku (score is not worth mentioning) and i am currently playing the black label version of it (very hard though

What i want is corrections about the statements i will provide below since i know really very little about the game. i really want to get into the game after i've played Deathsmiles for an indefinite amount of time and my first goal would be a 1cc.
So yesterday i played a bit (4 hours) of the PS2 version and the XBOX version. Needless to say that i got destroyed by the game i scored a lousy 22mio (PS 2 version) on my best run to stage 1-4. I played with Type B SHOTIA and what the heck.... she seems to be so slow when lasering. Question here is.... is she even a viable choice for a 1cc or am i crippling myself? I don't have tried Type A or other Elemtal Dolls yet but judging from alle the youtube videos TYPE B or SHOTIA seems inferiour... again am i mistaken?
Another problem here is that, like in every of their games it seems, CAVE has released like billions of versions of the game. I am at the point where i don't even know what i am playing. I read like 35 threads on this board and cave-stg but there is no thread like for fukkatsku where all the versions are listed nicely and differences are explained. I am totally confused. And i'm not confused about game mechanics since i don't understand them anyway at this point but the jungle of versions is bugging me.
What is the version of the PS2 i was playing?
What is White Label? Is this the Ps2 version?
What the heck is new arcade compared to old arcade mode on XBOX360? Which one is easier/ more 1cc-friendly? is old arcade White Label or the PS2 version?
Is Black Label on XBOX easier than the PS2 version or the ""normal" version? Sould i play Black Label for 1CC?
Is there a normal version of the game which represents the arcade/ PCB version or is this the PS2 version?
Do the the Ship Types or their behaviour in the game differ for any of the versions? I am asking this because i wanted to stick to B - SHOTIA, so maybe there is a version where she sucks less...or am i just too bad?
I think i scored better on the PS2 version, though the XBOX Version was easier... i know this is vague, but it seemed i got hit more often on the PS2 version but then again... what do i know?
I apologize for my terrible english (I'm from GER) and i hope this is not the 1000th thread of the same topic but i really searched the forum for information on the versions but couldn't find much except some threads wo went deeply into game mechanics.
Sincerly
