Hello. I'd like to request help extacting Ikaruga, which contains a few .ARC files. The BMS script doesn't work since it seems an update broke it, according to this thread.

I'm not sure that I downloaded the latest version of the game, but here new keys.

Code:

0x321C8EAB - "sdr.arc"
0x7F11D463 - "obj.arc"
0x7711A88B - "snd.arc"
0x7911B381 - "tex.arc"
0x4D11AC87 - "bin.arc"

If these keys do not work, then upload game.exe.

I forgot all about this thread. The keys didn't seem to work. Here's the cmd output.

Quote:

- the script needs to load a pre-compiled function from the dll or code
MEMORY_FILE3
do you want to continue with this and any other requested dll/code (y/N)?
y
- library MEMORY_FILE3 loaded at address 075D0000
- function found at offset 075D0000

Error: [myfseek] offset 0xc9b80322 in file -1 can't be reached

Last script line before the error or that produced the error:
44 goto dwNameOffset MEMORY_FILE

Press ENTER or close the window to quit

Here's what my BMS section looks like.

Quote:

get NAME filename
if NAME == "sdr.arc"
math dwMagicConstant = 0x321C8EAB
elif NAME == "obj.arc"
math dwMagicConstant = 0x7F11D463
elif NAME == "snd.arc"
math dwMagicConstant = 0x7711A88B
elif NAME == "tex.arc"
math dwMagicConstant = 0x7911B381
elif NAME == "bin.arc"
math dwMagicConstant = 0x4D11AC87

Here's the .exe.

Thanks for the help (and also happy new year).

That seems to work! You may update the bms list with that one. Thank you very much.

Script updated with the new keys.
