Enable Special Effects and set whether backgrounds and sprites will use them or not. This also sets the type of Effect

#define PA_DisableSpecialFx(screen)   REG_BLDCNT(screen) = 0

Disable Special Effects

#define PA_SetSFXAlpha(screen, Coeff1, Coeff2)   REG_BLDALPHA(screen) = Coeff1 + (Coeff2 << 8)

Set the special effect parameters for Alpha-Blending
