Well, after referring to this thread multiple times when looking for Touhou-related tabs I feel compelled to post some of the ones I've done in return. I'll disclaim that by no means are any of them perfect. (and many will be missing / have botched solos as I play rhythm mostly msyelf) I don't tab music often and only have really done so on this occasion because of the distinct lack of Touhou guitar tabs I can find on the internet, but hopefully they will be of use to someone as I haven't really had a good place to post them until now.

All Dark Phoenix songs are in drop D. (I will also note I have Dark Road from Witch Clocks figured out, but have yet to tab it if anyone is interested)

http://www.mediafire.com/?8y6aibdsgqdwqqn (This is still in progress, but a good portion is finished) Update 2: Further and further along, fixed a few segments while error checking with someone else's tab on Youtube.
The above I both have tabbed out for F# Standard.
Demetori - Deep Mountain - Album: 如臨深遠 ~雨縒煙柳~ -
http://www.mediafire.com/download.php?478zb59ifvwc9wt (Lead only so far, no chords. >.<)
E Standard.
Demetori - Greenwich in the Sky - Album : Sendaisoushi ~ Offering To The Sukhavati -
http://www.mediafire.com/?n42es2flc5wxw29I play it on a 7 string since I like adding the low B strnig, but you can easily play all of it in E standard. (Not close to finished)
Magnum Opus - Extend Ash ~ Hourai Victim - Album : 東方幻朧悠月抄 -
http://www.mediafire.com/download.php?8pzrz59woc49wgu (Mostly finished)
Eb Standard.
Tumeneco - If You're My Destiny Than End This Fated Determination - Album : 現夢 -genmu- Disc1 - (Arranged by Hull)-

Yamagen's Devileliet - Innocent Winner - Album : Grievous Graves -
http://www.mediafire.com/download.php?l4qh58p2a3f87i2 (I did this really quickly one day and haven't looked at it since, perhaps will edit it later but for now, you've been warned.
Drop Bb/A#
Undead Corporation - Bleak Land - Album : 私はもう死んでいる?-
http://www.mediafire.com/?r8g5g8rg01h8f14Drop A. (Also have "My Fading Days" "Frozen" and "Double Helix" figured out but not tabbed, if anyone is interested.
(Edit: Adore Your Pain finished but incredibly rough, I will post it once I feel a bit more comfortable with it)
Undead Corporation - Adore Your Pain - Album : 私はもう死んでいる? : -
http://www.mediafire.com/?a7qreq65uikubehDrop A. I tabbed it on my 7 again, but the tab doesn't even use the string that is different so it's no big deal. Rough for now, I always have issues hearing the lead guitar in UD Corporations' songs, but I've got (most) of what I could hear as best I can for now.
IOSYS (Minami) - Gorgeous Guardian - Album : 東方JeuXinTerdiTs -
http://www.mediafire.com/download.php?4dsfk204zbmm57v (Lead only so far)
E standard.
I'll likely try to keep updating the tabs in the future, but hopefully some of these help someone who may be interested.
Edit: Typo's :S
Update 2: Since it's been requested I figured I'd upload my beginning attempts at Greenwich in the Sky by Demetori. It's far from finished but it can give you a general idea of how the song and some of the riffs go.
Update 3: Adore Your Pain by Undead Corporation added, just what I have so far.
Update 4:
Foreground Eclipse - I Bet You'll Forget That Even If You Noticed That - Album : Each And Every Word Leaves Me Here Alone - Song :
http://www.youtube.com/watch?v=aSY05KRDXQ4 - Mediafire :
http://www.mediafire.com/?1t2gre4wet01d59Drop C
Notes: Now have both the Rhythm and the Lead done, everything save for the sweeping solo which I've been having some issues hearing but will get to eventually.
Update 5:
Xi-on - フォールオブフォール ~ 秋めく滝 - Fall of Fall ~ Autumnal Waterfall - Album : 東方志奏 1st Spell -Airstream- - Song :
http://www.youtube.com/watch?v=u_CNWYIRlt8 Mediafire :
http://www.mediafire.com/?7jbql59x7cw8ikeStandard E 6 string tuning.
Notes : The planets finally aligned and somehow I managed to make a tab with the full Lead Guitar. Unfortunately for you all that means the rhythm is yet to be tabbed out. I plan to later though, I just got through this all in one go and my fingers are killing me from all the bends. I had a blast tabbing and playing this, it's a really fun song to play.
