From your (8x8) Start Screen, set it to warp to a "buffer" screen, any normal screen (not 8x8) maybe a black screen with just a "LEVEL 1" written on it with tiles... set the "left edge stop" and "right edge stop" flags for that screen, also hide hud and sprites... set the warp in x,y coords... and the warp ou x, y to your real level screen.
Also, you could place a invisible monster on that prefer screen, that would ignore gravity and executes a WARP after a small timer value (maybe "4")
