Sega Mega CD ISO Hacks & Editors

[Tony H]

Forgot to add the .iso file extension to the list of files that you can open in these 3 Sega CD editors. If you already downloaded the older version (1.0) and you don't need .iso file support, then there's no need to get the newer version (1.0a). If you got the older version and couldn't open your Sega CD iso file, this newer version should fix that.

Final Fight (Sega CD) Editor
Popful Mail (Sega CD) Editor
The Terminator (Sega CD) Editor

Here's the updated versions (ver 1.0a)...

An editor for The Terminator (Sega CD). The usual stuff including all of the debug/cheat menu/level select/cinema sequence codes. Help button has all the info. An interesting side effect of the walk thru walls code is that if you walk out of screen to the left when you start a level, you will automatically get all of your bonus points and finish that level, and then go to the next one.




Update: Forgot to add the .iso file extension to the list of files that you can open. Fixed this in version 1.0a...

A code/cheat editor for Popful Mail (Sega CD). Should work on any file type (iso/bin/img), on any version, or with any region (hopefully). All codes should work on all levels.




Update: Forgot to add the .iso file extension to the list of files that you can open. Fixed this in version 1.0a...

Cheat editor for Final Fight (Sega CD). Made an improvement to the editor, so the patching process will be much faster now.

Finished a basic editor for Dracula. Makes the game much more enjoyable. I was really impressed on how they rotate the room around at the beginning of some of the levels. Wow.

Made some improvements on this editor: The previous editors only worked on bin (binary) and img (disc image) file types, but wouldn't work on ISO file types. This editor now supports ISO file types, as well as bin and img. I also noticed that there were several different versions of this game. I made it so that the editor will work on any version, and with any file type. As far as I know, this should be 100% coverage for this game, no matter what you have, and should even work on the Dracula and Frankenstein Double Deal version.

I hated those damn crows and bats that are constantly bombarding you, so made a code/cheat to have them die as soon as they touch you. lol.

A new cheat editor for Sonic CD (Sega CD). Sonic CD has 73 different levels, and each level uses it's own separate programming, and the special stages use their own programming as well. This editor patches all 73 addresses for each of the codes, so the cheats will work on all levels. If you check all 12 boxes/cheats, it will patch around 450 addresses in the 600MB Sonic file in about 1/2 of a second, so it's reasonably fast. With some more help from nolberto82, the pattern search that it uses to patch all of the addresses seems to be working perfectly now. Lots of codes/cheats to choose from.

Editor for Lunar: The Silver Star (Sega CD). Lets you enable individual parts of the debug cheats, have free shopping, experience points multiplier, etc. This one patches your bin/img (ISO type) files. As with all of these editors, cheats can be turned on or off. There is a readme included, but clicking on the Help button should answer any questions.

Liquidpolicenaut, I'm working on an EXP multiplier code for Lunar: The Silver Star and I've got a question. What is the minimum number of people that you would ever have in your party during the entire game?

EDIT: Never mind. After doing some reading, I see that you can actually only have one person in your party during battle if you have people run away.

[Tony H]

Beautifully done Tony! Works like a charm You truly do have some amazing skills in finding these codes...

Thanks, appreciate that. Working on the Lunar TSS editor. Will have the debug stuff, as well as no charge in shops, EXP multiplier, and one or two others.

With Lunar: The Silver Star, you can use the code FFE619:40 (or FFE618:0040) to enable all the debug stuff (Debug menu and press B to walk thru walls & no random battles). This is fine as long as you're using an emulator that supports the code (like some versions of Gens, etc), but I don't think you can use it with Kega Fusion, and of course you can't use it on real hardware. At first I was trying to force that code via a patch in the bin/ISO file. Got it working fine, but since then I found the routines for the debug menu, and the "press B to walk thru walls/no random battles". Will post the hacking/patching instructions for the two debug routines since that's a cleaner way to go, and you have the option of only turning on one or the other if you want.

Lunar: The Silver Star (Sega CD)

To enable the "Hold B to walk thru walls and have no random battles" cheat...
Open your bin/ISO/img file with your hex editor and search for the only occurrence of: 56F8CD3C. Change the 56F8 to 57F8.

If you want to have the cheat above so that you don't have to hold down the B button to activate it (you will always be able to walk thru walls, and you will never have any random battles), add this to the hack/patch above (will need to use both). Open your bin/ISO/img file with your hex editor and search for the only occurrence of: 64102F00303C. Change the 6410 to 4E71.

To enable the Debug menu (just press Start)... Very useful. Change your party's stats, warp anywhere, add or remove characters, etc. Too many things to list...
Open your bin/ISO/img file with your hex editor and search for the only occurrence of: 660000C0E300. Change the 6600 to 6000.

I will most likely write an editor for this, which will probably include a few more cheats.

Oooh ok. I actually already have a save file (not save state) in .brm format that I use with either Kega or Genesis Plus and that file starts you out at the beginning of the game with the debug mode enabled. I was seeing if you were able to hack it into the .bin file so, if one was so inclined, they can burn the actual file and play it in a real Sega CD with the debug enabled on it...

Ah, got it. I'll keep working on the bin version. Will keep you posted.

Or, if you want instructions for Retroarch Genesis Plus GX instead, give me some time to research it and I'll see what I can do.

EDIT: If you have a save state for Retroarch Genesis Plus GX, send me one if possible

[Tony H]

For right now, it would just patch the save state file. I've got an bin patch too, but I'm still trying to make sure that it's a "clean" code/patch. I hi-jacked some existing code that I think is safe (no side effects), but still have to test it some more.

If you want, I can post the instructions on how to patch your Kega Fusion save states, and you can see how it works for you.
