Thanks for the help. I don't think I will pursue this though -- my own engine is coming good, and trying to use this awesome Sonic Worlds engine for an 8 bit style Sonic game might be like cracking a nut with a sledgehammer.

This isn't a bad idea. They don't need to be scaled up that much, but 1.25 times the size would be about right (I think)... I tried this, but it doesn't look very good.

I feared this might be the case.

1. When standing against a wall, there is a few pixels gap between the player and the wall. There is no gap against walls in the original games (I checked on Sonic 3 - there is a gap at the left edge of the level, but not against walls). If you play as Tails, the gap is even bigger, and there is a gap when you hit against the ceiling. I gather this is because the sensors should be adjusted for smaller players. I would like to use sprites from 8 bit sonic (which are much smaller) -- which sensors do I need to adjust and are there rules governing the way in which I should adjust these to avoid screwing up the movement? 2. Thank you for the cut-down version. The reason I would want to start with a cut down version is that the later versions seem like overkill when trying to start off a game, and it might be a lot of work to strip away all the stuff I don't need (I don't want the title cards, gimmicks, music, enemies etc.). However, the cut down versions don't have as good movement in them, I gather.

*Why is the space around the player so large when I hit obstacles? *Is there a stripped down version of the engine (just with the movement)?
