I created an easy to use program that creates the anoying 8-bit bmp's required to have smashGpsp display the character pic's correctly.
Its very simple and all it requires is photoshop 7.0 or higher and that the folder named "Pic to 8-bit bmp" in the zip be placed in the C drive to work correctly.
It can group convert pictures and it can convert psd's to 8-bit bmp even if you have multiple layers.
To use, all you have to do is click and drag the picture or a folder of pictures to the exe file (it has an icon of an arrow pointing down).
The converted pictures are in the "Out" folder.
Currently i haven't implemented subfolder picture conversion, so if you have folders in the folder that you want to convert, it may give you an error or it may not convert at all.
