Question about beat em up

Hey guys. I started off with the base adventure module creating it exactly like the 20 minute tutorial video. I am now attempting to change and morph it into a side scrolling beat em up. My first biggest question is about my character. I want him to be the same size as characters in Double Dragon or the platforming levels in TMNT. So...
1. These sprites should be created at 8x16 correct? From what I could tell that was the size of characters in games similar to those that I mentioned.
2. If I create these bigger characters what scripts should I edit (and how) to my "base adventure module" stuff I added in from the tutorial?

You could try changing the size of your Player object, make the graphics, don't forget to change the bounding box...
Also, I'd strongly suggest to watch the other tutorial videos first... (all the videos from the website). To learn how to do all that
