I'm really amazed by the awesome optimized routines you keep writing for GBA. For a project I write, I heavily use plot on 4bpp tiled background (for a variable-width text system), and since my functions are horribly slow, I really look forward an optimized blitting function ! I really can't think to a way to optimize that 4 bits to 4 bits potentially unaligned transfer things, so I'll be happy to see how you've done it ! :) The download link for the new tonclib seem to be broken (or at least, it doesn’t work for me).
