Dunno... Do you set the table-adresses or do you assume them???

Then why do you trash the memory boundaries in a program of hardly a
kilobyte???
Even when you want to load a picture in one piece you only need 32k out of
48k.

About twice per year I always make a deperate attempt to make my code more
structural, but most of the time the result is that it doesn't work anymore.
:(
Anyway, if I've got it to work again I can always be proud at how
'structural' my code is. whow.

Sigh... okay, but I call it a secret mode.

256 bytes, eh??? Dunno, if I will have to put the palettedata in one large
table 256 bytes won't do. If I am able to calculate it in a simple and fast
way... I take the challenge.
