[Sonic 1] Extending Level ID's

NOTE: Basic ASM knowledge is needed to get successful results from this guide, so turn back now if you're not confident in your abilities.


If you've ever wanted to add extra level slots in Sonic 1, then this is the thing to try. Here is a list of every offset index in Sonic 1 that must be extended in order to do so.

Keep in mind that you'll want to make "dummy" slots for Level ID 07 and 08, as they're already defined for the object layout offset table. You'll have to disable the art replacement for when the title card goes away, or fix it so that the animals don't look like Eggman's feet or something like that.

 

Ah, this could be very useful! Thanks.
