I have a problem... I don't like the current CC palette......

I was wondering if the DRL Devs could perhaps try using RGBA (Red, Green, Blue, Alpha (Transparancy)).

I think that if they could then the current sprites would look even better and there wouldn't be any pixelation or colour replacements. I have tried replacing "Base.rte/palette.bmp" with a custom palette and it works but the images look all weird.

So if you could use the whole RGBA instead of 256 then I for one would be very happy.

Impractical.
I would prefer a fast CC.

but... You don't see other games lag out using every colour do you though?

Search next time.
The game is intended to have color restrictions, as it is supposed to have a retro feel to it graphically. The palette is also used for a number of other reasons that you won't get into unless you start modding.
As well, it's not a particularly large factor, but full 32-bit color can in fact lag quite a bit. There is already 32-bit color in CC - glows. If you disable them, you'll notice a small performance increase.
