Transparency

Does anyone have a fast method for drawing sprites with transparency in real time?

I have tried using alpha blending but even to draw 20 8x8 solid rectangles over a background takes about 13ms - way too long to include in an arcade game frame render.

i'm working on a 2D engine for b+ with it i can render 120 alphablended 32x32 sprites in 20 ms
20 32x32 in 4 ms :)
20 8x8 in less than 1 ms

the code do all graphic operation to a memory buffer
then copy the buffer to the backbuffer

it's not finished but i can give it to you as is if you're interested let me know i'll mail you the source.

I've sent you a mail using your profile contact details.

Cheers.
