Change tile art

Hi. You may know that to make a hack look different, you got to change some sprites and art. In this tutorial, I'll show you how to change tile art with SonED2.

Step 1: Resources

What you will need for this tutorial: Sonic 1 GitHub Disassembly, SonED2, and, a Genesis Emulator

Step 2: Load a level in SonED2

To load a level, you need SonED2 open. Then click "File" >> "Open", then go to your directory of the disassembly (mine is E:\Sonic Rom Hacking\Sonic Chaos\s1disasm-master\SonED2 Projects\) For this tutorial, we're gonna do Marble Zone (in my hack, known as Blazing Ruins Zone). You should see Marble Zone's layout and object placement. At the top of the window, click "Editor" >> "Tile Editor"

Step 3: Actually changing the art

This part is tricky. Click "Tiles" and then you should get all of the tiles for Marble Zone. Though.. doesn't the color look incorrect? That's because the tile pallet section is on Sonic's pallet. Click the third T on the third row. That looks correct doesn't it? Now select a tile... and start DRAWING!!!!

Step 4: Compile and test

Once you're done editing your custom tiles, click "File" >> "Save Project". It will take a short amount of time to compile the code and boom! Done! Now go to your directory of the disassembly. Open build.bat and wait. When you see "s1built.bin", that means you're ready to go! On the title screen, enter in the level select code (Up > Down > Left > Right > A + Start) and select Marble Zone. You should be able to see your edited tiles. If not, you may have done something wrong. Anyways, happy hacking!
