[Guide] Almost Unlimited Flying Height

kotarou3 · 07/09/2010, 05:50

You don't have any advantages if you edit the flying height. You might have a disadvantage of taking longer than usual to land again if you fly too high though~

Open Standard.dll with IDA (Default options are fine)
Wait until autoanalysis finishes (And change to text dissassembly if you have IDA Pro)
Search for "GetCeiling" in the functions window and double click on the function found
Copy the address of the function and go to it in OllyDbg
Change the first JE into a JMP
Right click the place you just changed and click Copy to Executable->Selection
Go back to IDA and look for the last fld
Double click the text after the fld ds: and copy the address you land on.
Go to that address in OllyDbg and press Ctrl+E
Uncheck "Keep Size" and replace the 00 E0 with FF FF 7F 7F
You should have two red lines, the first reading FF FF ???? and the second reading 7F 7F JG SHORT Standard.XXXXXXXX with XXXXXXXX being a hexadecimal number
Right click the first line and click Copy to Executable->Selection and repeat for the second line
Save the executable and your done!

Thank me if I helped

Note: The "Almost Unlimited" flying height sets the limit to 3.4028235x10^38 which is (In 32-bit float) Infinity - 1 (Infinity = 7F80 0000, 3.4028235x10^38 = 7F7F FFFF)

Looks good...

For some reason, I'm unable to edit Mabinogi related files with OllyDbg I'm using a 32-bit and I start the .dll from the Mabinogi folder.

Any ways to edit it directly with IDA Pro?

Unfortunately, I dont know how to edit with IDA

Halfslashed · 07/09/2010, 07:11

Not really possible, either.

kotarou3 · 07/09/2010, 07:15

I've heard its possible. Also, go to File->Produce file and there is options for both an EXE and DIF files

You can edit all mabi related files in olly.

Run it, tell it to load w/ loaddll.exe or whatever it was, and then click "run" twice. Don't know why that's required, but then it'll load the file into memory.

No clue why, but... it seems to work? =D

Can't you just save everything in the end once? ._.

kotarou3 · 07/10/2010, 02:11

No. For some reason, Olly doesn't let you save everything at once when your editing the "non-executable" code

what's the point? you can also do this with certain xml. Only advantage is people can't see you flying if you are above certain meters.

For fun?

More point to his post than yours. This would go with the saying that there's more than one way to skin a cat. Edit the xml, edit the game files, whatever.

aviationdescription probably

fenrir2037 · 07/12/2010, 15:34

Probably? Correct me if I'm wrong, but if I remember the xml edit still let others see your mods. IE: Tiara take off/landing speed....

Me and my friend tested this, he said he did not see me moving at abnormal speeds and even when I flew upward or downward on his screen I always maintained a constant height.
