OK, so I decided to change my PSP 01-12.bmp file.
I created all the 12 bmp files needed, and according to a guide, I should join them in one single BMP file.
I did that according to the guide... And replaced the original file in the PSP with my own...
Thing is... It only loads the first bmp file (january) ... not the other ones...
Any help? tnx in advance.
