Crashman's Tilemapping routine works fine on the 83+ with some _small_ modifications. To make 16x16 sprites use ionLargeSprite. Ex: ;----ION LARGESPRITE ---- ;Input: a-x coordinate ; l -y coordinate ; b-height ; c-width in bytes (16/8=2) ; ix-sprite drawmysprite: ld a,0 ld l,0 ld b,16 ld c,2 ld ix,bigsprite call ionLargeSprite call ionFastCopy TCPA's tilemapping routine is also very good. -Cole South
