Good work! Mustapha, I'm working on bosses too: EHZ, CPZ, ARZ and MCZ bosses for my hack. Instead of disabling parts of the bosses, I want to copy them (Having 6 wheels instead of 4 for EHZ boss for example), move them, and then I will redraw them to create new bosses. I will try to find some things myself with all the informations you've written here for CPZ and EHZ bosses. I know some little things about ARZ boss, like repositionning arrows and totem poles. Have you some informations about this? This will help me A LOT in my work... :P
Since I know how bosses... all objects in Sonic 1, 2, 2k, CD work, I can help you to find what you need for the ARZ boss. I just need to finish the Sonic 1 Time hack. Contact me on AIM for a faster guide: losttmd
I worked 8 hours on bosses today. I know more things than before now. I have found how the huge boss sprite works for every bosses, and I'm sure I'll be able to make something good for my hack and the Community after this research. But strangely, there is something I can't find: where spikes and stones in MCZ boss are located. I can remake EHZ, CPZ and ARZ bosses almost entirely, but it lacks me this to remake the MCZ boss. I have to search a little more with my hex editor... EDIT: I can't write something without English mistakes.
I'm quite glad to see people are interested in hacking major objects such as end of the level bosses! I hope one day, I could be at your level of boss hacking. My dream is to create a custom boss that I could call my own! Why don't you try: $313F2 - At this offset, you disable the rocks and sharp pointy objects that children should not play with because it will hurt them. To disable said rocks and pointy objects, replace 66 with 67! You could use that offset as a lead to finding what you need to find. But I'm sure that you've found a solution to your problem already, and don't need any of my assistance. :P Good luck with your boss hacking!
