This is now a general Sonic Jam hacking thread! The Community Hacking Guide for Sonic Jam can be found here. This thread originally started as a model-swap project for Sonic and Tails, which is detailed below in the original post. -------------------------------------- Hey all, First non-verification post here! On-and-off for the last two years or so, I've been doing all sorts of digging around in Sonic World in the hopes of laying some groundwork, and maybe getting people interested in hacking the game. A little while ago, I managed to piece together how to swap models! Here's a video of Sonic's model having been replaced by Tails', running in Mednafen. Some textures are messed up, you might notice. I'm pretty sure this is due to the code that makes Sonic blink; I still need to dig into that. His proportions are also a bit off when sprinting or jumping, cause at recording time I was too lazy to go through and update his sprinting and jumping models' component positions. I originally did this via real-time memory editing, but I've since hex-edited an ISO to achieve the same thing. I've got a Google Drive full of notes on basically everything I've dug into, for anyone who'd be interested... See here. I want to go through and really clean them up at some point, but if ya just can't wait, they'll do fine for now. Though I apologize for any confusion in advance!
