Problem with virtual console games

I have been trying to make codes for a virtual console game: Sonic the Hedgehog for Sega Genesis

The codes work fine for the most part. However I have noticed that if I uninstall & re-install this game, all the addresses change. They do not change until then though. Occasionally I can uninstall & re-install without them changing. To force them to change I have usually installed a few other games in between (this seems to overwrite the old one on the harddisk) or even deleted the save file for the virtual game.

I want to know if this is fixable. Using pointers does not seem to work (unless I am doing something wrong). I can provide the .wad file for this game if it necessary for testing. Thanks to anyone who helps.

You should try to make pointer codes. I´m pretty sure it´ll succeed.



If it really does NOT, your last resort is ASM. This program will help you greatly.

I find it weird that the addresses change if you delete and re-install the .wad file. They usually change on restart of the game or when a different level is played...

That is the exact reason I am confused also. I will try your advice though. I have also noticed that most of the virtual console codes on geckocodes.org don't work for me and this could be for the same reason. Thanks.

Yep. If addresses change *at any time*, you´ll need to do a pointer search. Some games have moved addresses when the language is set to something else. Sometimes ASM moves, too. That could turn painful. But on the bright side, these kind of games usually don´t have moving non-ASM addresses. Combining ASM with pointer is possible aswell. F6 is also an option, I´ve seen people using it instead of ASM.

There´s basically always a way to make a code. I haven´t seen something impossible yet. Coding is so diverse. I surely haven´t seen everything already.

It looks like a good learning experience and a good challenge. I'm going to try and figure this out. Although I know very little about ASM so far, maybe this can help teach me some things.


EDIT: I have absolutley no idea what causes the change of address. Sometimes it happens when I delete the save file. Sometimes it happens when I re install the game. Other times it will not change no matter what I do. I am extremely frustrated with this problem.

I am trying to make an infinite rings code sometimes the value it at this address:
80E832A0
Other times it is at this address:
8080E600 (GMO in the geckocodes database has this address)

It never changes to anything else(AFAIK). I have done a pointer search several times and received no results. I think I'm going to give up figuring this out.
