The backgrounds on and working but when my sprites move they are slower. How do I stop them from being slow?. P.s I use texture backdrop for background.

Use the SET SPRITE command to switch of the backsave feature. You don't need it because the background is being redrawn automatically every frame by the textured backdrop.

Adding a backdrop will slow your game down, just move your sprites around with higher values to compensate. It's tricky, but perhaps you need a time elapse system so that the speed is constant. Basically every sync you'd check the elapsed time in miliseconds, then multiply all your movement speeds by that, Wolf posted code for this some time ago. It also means that the game runs at the same virtual speed on any PC, a sprite moving along the screen will move at the same speed on any PC, but a faster PC would be smoother.

You see games like mario and metroid well how would I make it so there are platforms to jump on and how would I make the game sidescroll and follow the character?

Usually, the best way to add platforms is with a map array, say ever 16x16 pixel block on your level is refered to with a 2D array. You would use this to draw the level with Paste Image or something, then use it again for collision detection. In mario, the background could be a long image that is repeated, then you'd just have to draw the ground and any platforms on the screen at any 1 time. You could pre-draw the whole level, but that means really big bitmaps. There are lots of 2D engines that use this method, why not take a trip to www.underwaredesign.com and look through the code snippets.
