With SuperBasic sprite graphics need to be loaded to memory blocks starting addresses only, e.g. $30000
Sprite file headers start with 3 bytes ($11 to indicate sprite binary starts, $03 $00 to indicate sprite size, e.g. 32x32 pixel).
This in turn means that sprite graphics data starts at an uneven byte which is not supported by core2x.
Adding or deleting e.g. $00 bytes in order to come back to even addressing scheme doesnt work.
