Library History:
This library project is started as just a VIC library by Skate at the end of 2005 for internal usage. But after using it in various projects, new features and even new libraries are added. But currenty (r1) math and memory libraries are very poor. But VIC library seems ok. I don't like to use VIC addresses with labels. I mean I prefer to write $d012 instead of RASTER_POSITION etc. So, if you are familiar with VIC, you will be able to use everything as they are but you'll have some additional macros and sub routines. If you are new with VIC, read some documentation on VIC, then my library will save you from some bit calculations which is a big headache for beginners.

What are the advantages and disadvantages of sk8lib?

VIC Library

+ Easy to use constants like "Screen Mode Constants" and "Sprite Constants"
+ VIC library includes only macros and it doesn't use any zeropage addresses or any memory address at all
+ "SetScreen" macro is very powerful. Specially PC kids will like that one :)
+ Optimized for not wasting any cycles. For example if you want to set first 3 sprites y coordinates to 50, you need to write:
