 An undocumented feature you will like- remember TI's canard that you could not have sprite automotion in bit map mode? This is repeated in the Myarc XB manual I have - but in truth. you CAN switch Myarc XB to bit map mode. and then call sprites with auto-motion. Neat.

			To return to MYARC XB from FUNLWEB 4, do not use the RETURN TO XB option as that only works with TI XB. Instead go to DM1000 and choose the CART RAM option- this will cause MYARC XB to be reloaded from disk (do keep the Myarc disk in place for this!) as the Myarc module retains the loading routine all the time as noted by Tony.
