Hey Tony, do you think you can post the actual hex codes to edit in Lunar TSS of the values for the exp. modifier and the values to start with $10000?

Hey Tony, do you think you can post the actual hex codes to edit in Lunar TSS of the values for the exp. modifier and the values to start with $10000?

No problem. I couldn't find my notes on that, but then remembered that I can just use the source code from the editor. lol.

Lunar: The Silver Star (Sega CD) hacking/patching info. Should work on any version...

To start a new game with more money:

Using a hex editor, search for the first occurrence of 00DC0000
00DC0000 - Before you make any changes.
27100000 - Change the 00DC to 2710 (only do this to the first occurrence). This will let you start a new game with $10,000.

You can change the 2710 to any value you want in hex from 0000 to FFFF ($0000 to $65,535). Although I haven't tried it, you can probably change the bytes before that if you want values higher that FFFF ($65,535).

-----------------

To change how much EXP you get after battles:

Using a hex editor, search for the only occurrence of 8EC066027E0148C7
8EC066027E0148C7 - Before you make any changes.
What you change depends on how much experience you want after battles. Here are some examples:

4E714E714E7148C7 - Change the 8EC066027E01 to 4E714E714E71. This will give you 3x to 5x more exp.

CEFC00024E7148C7 - Change the 8EC066027E01 to CEFC00024E71. This will give you 6x to 10x more exp.

CEFC00024E7148C7 - Changing that red 02 to a higher value will give you even more exp after battles. 03 gives you 9x to 15x more exp, but I haven't tried anything higher than that.

Have a few done and working on a few more. Kind of a fun game. Zero codes for this on the site, so it's wide open.

Please note that these patches will only work if you start a new game, or use an "in-game" save file. These will probably not work if you use an emulator save state.

Dungeon Explorer (Sega CD)

Open up your Dungeon Explorer ISO/bin/img file with your favorite hex editor.

Walk thru walls, over water, etc.

Note that it is possible to get stuck when entering some buildings (only happens when you enter at a certain angle). If this happens, you can press Start + A + B + C, and the game will do a soft reset and you can reload your previous save point. EDIT: Also, enemies can't follow you into bushes, walls, etc.

Search for 4 occurrences of 670207C45079000076 (one occurrence for each direction: Left, Right, Up, Down).

In each of the 4 matches, change the 67 at the beginning to 60

670207C45079000076 Before
600207C45079000076 After

------------------------

Get more gold from the piles of gold on the ground (not sure if it works on other gold things).

Search for the only occurrence of 000FD480.

To get about 10x more gold from gold piles, change the 000F at the beginning to 00FF

000FD480 Before
00FFD480 After

To get about 100x more gold from gold piles, change the 000F at the beginning to 0FFF

000FD480 Before
0FFFD480 After

-----------------------

Get the maximum amount of gold ($999,999) when you pick up a pile of gold on the ground (this may also work with other times where you get gold).

Search for the only occurrence of 6306243C000F. Replace the 6306 at the beginning with 4E71

6306243C000F Before
4E71243C000F After

A couple more

Dungeon Explorer (Sega CD)

Start with 1500 Food whenever you leave a town (instead of 1000)

Search for the only occurrence of 03E83B40. Change the 03E8 at the beginning to whatever value you want (in hex). Will use 1500 for this example:

03E83B40 Before
05DC3B40 After

----------------------------

Have infinite Food when you're out exploring (away from a town)

Search for the only occurrence of 53416A06. Change the 5341 at the beginning to 6008:

53416A06 Before
60086A06 After

[Tony H]

Dungeon Explorer (Sega CD)

Infinite Life

Search for the only occurrence of 936D77AE. Change the 936D at the beginning to 601A:

936D77AE Before
601A77AE After

[Saturn025]

Thanks for these codes, Tony! Been playing Dungeon Explorer a lot the last week and having a blast.

[Tony H]

Glad to hear the codes are working out.

[CloudXIV]

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...

I have 4 bin files, it only lets me patch the first one, which is 401mb, but the editor makes a 2,75mb file out of it, so I'm assuming something went went wrong.

Edit: Tried a version with a single bin file, same thing happens, I get a 2,75mb file.
