Sega Mega CD ISO Hacks & Editors

[Liquidpolicenaut]

I've started working on the debug menu for Lunar: The Silver Star. What exactly are you playing on? If it's an emulator, which one? I've got a clean code for emulator save states to enable the debug menu, but I need to know which emulator you're using. I may just make an editor that can figure out which emulator you're using (by looking at the save state), and patch it accordingly. If you're using something else, I'll need to know what kind of save state it uses.

I usually try it out on Kega Fusion but I'm currently playing it on my Retropie which uses the Retroarch Genesis Plus GX emulator. So would this code patch the actual .bin file or just the save file?

Awesome work on the editors! I have 2 requests, if possible:

1) For Lunar: EB, is there a way to increase the exp. gained to 10x? Anyway to also add in one for Magic Exp. gained?

2) For Lunar: TSS, is there any way to hack in the debug menu to be available from the start?

Thanks for any efforts!

Another editor for Lunar: Eternal Blue (Sega CD). This one gives you complete control of all the debug features and cheats. As usual, all of the cheats can be turned on or off at any time. Unlike the others, this one edits your backup RAM file (brm).

Ecco the Dolphin (Sega CD)


Enable Debug menu (Pause the game and press Right). Ecco normally has to be facing
the camera to access the debug menu, but this hack allows Ecco to be facing any
direction, and shortens the button sequence to a single button. Menu has level
select, infinite health, infinite air, etc...
Part 1: With your hex editor, search for the only occurrence of 65F00C050008.
Change the 0008 to 0001 (should look like this when you're done: 65F00C050001).
Part 2: With your hex editor, search for the only occurrence of 08000000670A.
Change the 670A to 4E71 (should look like this when you're done: 080000004E71).


Swim thru walls, rocks, etc...
With your hex editor, search for the only occurrence of 6E0001E2.
Change the 6E00 to 6000 (should look like this when you're done 600001E2).


Invincibility (can swim right thru enemies) & can swim thru walls/rocks . Turns
off collision detection. Doesn't work against spikes. Can still die if you run
out of air...
Part 1: With your hex editor, search for the only occurrence of B0836C00.
Change the 6C00 to 6000 (should look like this when you're done B0836000).
Part 2: With your hex editor, search for the only occurrence of B0836C72.
Change the 6C72 to 6072 (should look like this when you're done B0836072).

I made some cheats for Lunar 2 using retroarch.(HP,MP,Current Mgc EXP)
would it be ok if i posted my retroarch cheat file here?
i have used the mp codes most of the way through the game with no issues.

Tomcat Alley (Sega CD)

Aim Assist (will always hit enemy, no matter where you shoot).

Using a hex editor, open your ISO/bin file... Search for the only occurrence of 0023673C. Change it to 0023603C.

Works best if you start a new game (doesn't always seem to work when using a save state).

There are two separate searches/replacements that you have to do for the EXP multiplier in Lunar: Eternal Blue.

Search for the only occurrence of: 90390002E4B84880. Change it to: 4E714E71424070?? (70?? determines your multiplier value (in hex)). If you want a 20x multiplier, use 7014, if you want a 25x multiplier, use 7019.

Search for the only occurrence of: 8CC033C6. Change it to: CCC033C6.

Thank you again for the code, it worked perfectly!

No, Your doing it right. That's how hard it is to do. Believe it or not the first stage is the easiest. As far as Easy goes... You have to anticipate the enemies movement and if you can get the Green Box close enough to the enemy it will eventually turn red but only for litterally a split second for the player to quickly hit the fire button. I'll make a save state during The Bomber. Because he moves ALOT slower and it should be easier to lock on long enough to see what the game is up to. I'll see if it's been 14 Days since I left Discord so I can join back. I had to leave again because the requests got way out of hand to the point I had 30 or so PMs about games people wanted codes for. I just couldn't keep up. I feel like Nolberto in that sence and will likely make my status, "No Requests" Lol.

Hey, It's been a while since I posted on The Forums. However I have a request for Tom Cat Alley on Sega CD. The current codes on here work great and certainly make the game a bit easier, However is there any way to get a code that could make it so you are always locked on to the enemy air craft? So all you would have to do is press the fire button and never miss. The game is sometimes miserable being so hard to lock on. If there was a way to make shooting down enemies easier and less aggrivating. The game might actually become something to look forward to instead of dread. Lol. Anyhow, Any chances of that?

I'm having a difficult time playing this game and need a little help.

For starters, am I trying to get the green cross hairs/reticle onto the actual enemy aircraft that's moving all over the screen? I read that the green reticle is supposed to turn red when I'm locked on, but I've had the reticle on the enemy several times and it never turns red. Am I doing something wrong?

Is there a part in the game where it's easy locking on to a target? Like maybe the bomber in the first mission, or a ground target or something? If so, any chance you can make a save state shortly before that using Gens Tracer?

Ooooh ok.. Thanks for the detailed explanation! If you would be able to post the hacking/patching info for the experience multiplier that would be awesome! Thanks again for going through the trouble of finding all these codes...

Man, you REALLY have some skills in finding these codes! The editors work like a charm Quick question, though... Would you be able to find the codes for Lunar EB to multiply the exp, money and magic exp by like 20 to 25x? I know the editor has codes for saving and upgrading regardless of the amount of money/magic exp. but I kinda like upgrading at each level lol. You don't have to go through the trouble of creating an editor for it, just the codes to Hex edit it would be perfect. Thanks!

I had plenty of room to make changes to the existing code for the EXP multiplier, but not enough room for an 'easy' Magic EXP multiplier code. I can have it jump to another empty/unused section of the ROM, do the necessary changes there, and then have it jump back, but too much time involved in doing that. As far as the money, I haven't checked that, but I assume you would want all 3 multipliers (EXP, Magic EXP, and money). If you'd like, I can post the hacking/patching info for the EXP multiplier if you want to change it to 20x or 25x.
