I just bought a new cartridge of super metroid, it is the US version. maybe im doing the horizontal bomb jumps incorrectly but i lay my first bomb, wait. lay my second. im blown up in the air lay my third. everything is solid. i go the direction i want. but maybe half a second after my third and last bomb goes off. and all explosions are done. no more bombs are out. i hit what seems to be an invisible wall. all my momentum goes to 0. occasionally it doesnt happen. one in every 20 id say. is my cartridge messed up or am i doing something wrong?
