A Microbee developers graphics editor for PCG and screen stuff.

Some notes to get you going. Text entry in pygame is a dog so the filename entry field is very basic. Click in there to enter a file name and then load the PCG,Colour ram or video ram areas or save etc.
If you are editing a multi-character graphic then you can put the mouse over the character on the left of the character you are going to edit in the pixel editor and press the L key, this will put the left most column of pixels of that character in the shadow area on the left of the pixel editor and likewise if you press R it happens for the right most column of pixels. Soon the same will apply to the T (top) and B (bottom) rows. That makes it easier to align pixels as you edit.
