OK, I can see it now. What did you need to know?

[Mezmorize]

What would make my day is an actual multiple level up after battle.

You can try this one out.
The code makes you gain more and more experience the more battles you fight.

Lunar: Eternal Blue (U)
More Experience After Battle
1A92209D - Search for this hex string with Hex Workshop.
1A924E71 - Replace it with this.

Instead of your previous exp being reset to 0 at the start of the battle, it gets added to your exp after battle.
For example, with a brand new game started, the first enemies give 2 exp a piece.

First fight of the game, you have no previous exp to be added. Two enemies at two exp gives you 4 exp.
Second fight of the game, you have 4 exp from the last battle, this gets added to the 6 exp from killing three enemies. (10 exp instead of 6 rewarded.)
Third fight, 10 exp from last battle gets added at the end of the battle, etc. (16 exp instead of 6 for killing 3 enemies.)

i did some research and i think gen emulator shows the address. so my question is, if so, how do i get the address from there?
or does cheatengine picks up the address n from there i can search threw hex editor?

[BALDOGON]

@Mezmorize, Big thanks!!
Can this be done the same way with Lunar silver star?

[Mezmorize]

@Mezmorize, Big thanks!!
Can this be done the same way with Lunar silver star?

Yes, I'm sure it can.
I'll try to do that game next then.

Another code for Eternal Blue that is applied in the same way:
Infinite Item Usage/Duplicate The Last Item In Inventory After Using An Item
67064229 - Original hex string.
67066002 - New hex string.

Note: Go to Item->Drop and throw away your final item in inventory if you want Infinite Item Usage instead of the ability to duplicate.

@Mezmerize,
What emulator did u use these codes with to test? Reason i ask is cuz im using fusion v. 3.64 with all my sega cd+cheats n work.
But when i put lunar EB with new codes u put above, i can see the screen. During intro then hiro in dungeon running from fire montster, the screens turn to green n red stripe n can't see wats going on but i can hear the audio...any idea?
i'm gonna double check my hex iso to make sure i put the correct new hex string! brb.,..

[Mezmorize]

I didn't actually patch the ISO, I was just manually modifying the game while running.
I'm using Cheat Engine and Fusion v3.64 also.

So both codes are doing that or just the last one?

[BALDOGON]

Ok, i double checked the iso via hex editor n i input the new string written above downloaded a bin, cue to see if it was the prior iso image i ised..testing brb..

also i tried to use Cheat Engine and Fusion v3.64 but it wouldnt show me the games actual addresses, only moving red numbers..
i know im doing something wrong, can you guide me..brb..itro almost done to test codes..

[BALDOGON]

ok, so it is the codes thats doing that.(first code)
second code works...
bummer, i was so hyped to play with the level up...

[Mezmorize]

Sorry about that, guess the game uses that line of programming for something else too.

You can manually try to enter in the cheat with Cheat Engine.
Once you're successfully in the game ready to battle, attach Cheat Engine to Fusion then:
1. Press the Memory View button.
2. Click on Search->Find memory.
3. Click Array of byte.
4. Change the From box to: 00000000
5. In the blank text entry box paste what to search for (1A92209D) and click OK.
6. Change the 1A92209D to 1A924E71.

[BALDOGON]

Fusion 3.64 is very stabled emulator, i played all my sega cd on it. to bad in doesnt have a built-in code address like Gen!
Your item codes works with no problem..

[BALDOGON]

Great, you are AWESOME!! I'll give it a go n report back!!

Great, it worked, awesome...now if i can only make it work on the iso w/hex to run on fusion..

Ok, figured it out, so ran the cheat with fusin 3.64 n cheat engine as per instructions above.
After a few battles and level ups, i saved state, then closed cheat engine n fusion. Opened up hex to find the string(1A92209D) n
change it to 1A924E71 and save. close hex then run the iso lunar EB i just patched with fusion 3.64 emulator.
Start new game and when the intro starts, load state and your saved game will start with the cheat codes intact!!
With these hex codes for some sort of reason when u start a new game with the hex patched iso with any emulator, when you get past the intro n in the cave the picture crashes with audio still playing then crashes..

Big THANKS to Tony Hedstrom & Mezmorize for the HUGE help and CODES!!!
