Source code should be heading your way. I hope the e-mail address is correct; I wasn't sure if the repetition in your address was intended or not, so let me know if you don't receive it.
Sorry for the slow response - I didn't notice your message for a couple days. Sure, you're welcome to see the source code. To what e-mail address should I send it?
If you haven't figured it out yet, the main trick to effecient bitmap rendering using GDI+ is to make sure that all your bitmaps are converted to the PARGB32bpp format. If you use any other pixel format then performance suffers a *lot*. With Malastro I don't worry about keeping track of which areas of the screen needing updating; it redraws the entire map for every frame of animation, but with the proper bitmap format performance is OK.
