The 3-world demo should be up before Christmas. I just have to take some screenshots, make some minor adjustments, and create the IPS patch.
EDIT: Well, the demo WAS up, but it was removed due to an oversight on my part. I'm currently working on a FIVE world demo that'll include custom bosses and a few ASM patches.
Here are some shots showing off my recent progress.
This section of the fortress is inspired by Super Mario Bros. The fortress isn't a remade level though.
This is the Overworld map for the underground section of Misty Mountain Mines, the hack's 5th world.
Misty Mountain Mines 2. I actually built this level prior to starting the hack, using Hacks 101 as a sort of sandbox.
That black-shelled Koopa is a Koopa Bomber. Stomp on him, and his shell will explode.
Venus Fire Trap. Unfortunately, Classic Piranha Plants who share the stage with this enemy have red stems since I couldn't get the Piranha Fix patch to work.
