Hi,
I have done a first test to display in the sub screen an image in tiles mode but I get nothing (except some pixels), maybe someone can help me ?
I have first decomposed the image in tiles with "gfx2fba -t8". The tiles are in stage2.bin.
here is the code modified from an example. the part of the example works fine (display of an image in the upper screen in bitmap mode), but my part works not lol ! I want to display tiles in the sub screen, this part works not.
