It's not from an emulator, it's from Cheat Engine.
I notice that there is a brand new version 6.0 out, but seems like it needs some bugs worked out.

I use Fusion for all my Sega hacking (which I should get back on tomorrow).

I'll take a look.

@keeper7
I notice you have Corpse Killer codes, did mine not work properly?

It is working perfectly. I finally finished Corpse Killer using your codes.
Btw, Which emulator is this memory viewer from? I was trying to find codes for Road Blaster FX (J), same as Road Avenger, but I got black screem using Gens.

I used to get EGM, the Unofficial and Official PSX mag, Tips and Tricks, and so many more.
Stupid me got rid of them all over the years though >.<
I guess I never really considered that one day I would still be into the old school games lol.

The only magazines I still have, are some comic books.
I plan on scanning the gaming ads in them soon, and posting them here.
Basically NES-SNES period of ads, one or 2 Sega CD and PSX ones.

Thanks a lot Mezmorize for all of the great patches. I'm downloading each one and putting them in a folder. One day I'm going to go through all of my Sega Cd's and patch them.

I remember that page from EGM magazine too. Im sure I have that issue somewhere.

I was wondering if these kind of ips patches are possible to do on Playstation 1 games? That would be soooo great!

I love Earthworm Jim. Now temptation has set in and have no choice but to download the Sega CD version. I used to have an actual Sega CD and the game and missed playing this version alot. Thanks for the patch Mezmorize. Great job!!

Thanks, glad you enjoyed it.
I never had a Sega CD, just the Genesis (and EWJ for it).
I then went from the Genesis to PS1, and have had Sony ever since.

Mezmorize, if you could actually make a disc cheat device for Sega CD, you could make ALOT of money fast since SEGA themselves never made a cheat device for this console. I never heard the reason why they didn't. Weird.

There was actually going to be a Game Genie for the Sega CD (see attached image).
But after all these years, it seems like someone would have came up with a homebrew RAM patching cheat disc.

After reading Tony Hedstrom's Gens Tracer Guide and M68000 Instructions Manual, I think I'm beginning to understand how to make cheat codes.
I made some all by myself.
Well, sort of...
Chuck Rock 2, Flashback and Mortal Kombat I just converted existing Mega Drive Galoob Game Genie codes. You can find same strings on both versions, cartridge and CD-Rom.
Mezmorize, I hope you don't mind if I put them here.

I don't mind, it's good to have them all at one place.

Excellent work!
Now I won't feel so overwhelmed with all the games to be hacked.

You know, I never would have thought to port codes from other systems.
