Minimig AGA 060 RTG

[unusedunused]

You can see here a working version of Picasso 96 RTG driver for the Minimig's built-in graphics card.
The Replay FPGA board with 060 daughter board was used as the hardware platform.
It's not complete yet and there is still a lot to do but at least you can see the picture .

great, also dont forget to add a fpga function for alpha blendet blitting.SDL is able to use a Hardware alpha blend blit function

So SDL Programs can run lots lots faster on a minimig AGA RTG
maybe you get in contact with natami team so, the calling syntax can be the same, and not diffrent versions in SDL are need.

I see in MOS powersdl, there is a call to do alpha blit on AOS.the source is in AROS too, its only software in this bltbitmapalpha func, but when call the minimig Blitter which can do alpha blitting this can do in hardware extreme fast.
