fail attempt on changing default aura

[Hunt]

FeelRO should be type II/III (terminology of creative editing) but I can still kinda change the aura by creation of data folder only.
The files

(click to show/hide)

The order at data.ini is (sdata isn't here though)
0=feelb.grf
1=feela.grf
2=feelro.grf
3=data.grf
4=sdata.grf

From what I have read at eathena, I should just put three files namely aurafloat.tga, auraring.bmp and freezing_circle.bmp into feelro/data/texture/effect.

Here's what it looks like, as you can see, I am not able to override the aurafloat.tga.

I look into feelb.grf and feelb.grf, can't find related files, but for feelro.grf(greatest size), I found the files for the red aura.

Apparently there's one more file aurafloat.BMP, it's a .bmp not being able to preview. I extract them into feelro/data/texture/effect. And let my blue aura files as well as aurafloat.bmp working. The red aurafloat is gone... but my blue aurafloat isn't there neither.

Thanks for the help =D it would be also appreciated if bleu can make a guide to edit aura (please tell me if there's one).

Um..I think you'd have better luck on eA than here..On another note..um..Does feelRO like it when their players edit the files?
