Transparent stage textures

[Segab]

So this is what my stage is supposed to look like. The round thing in the middle is a teleporter from VVVVVV, and it's a transparent texture.

here's a screenshot of how the texture looks like in BrawlBox, in this case I picked CI8 format with RGB5A3.

but if I launch the game, this is what happens:

it changes the texture to another texture..?

I've tried picking another texture format when importing, and I get this instead:

Ask for Mewtwo2000, it's the best with Stage hacking.
