While adding a custom attack skill I would error out on loading until I made some room by deleting some lines in the cabal.enc I didn't need. Now it's shown me there is a limit to how much cabal.enc can contain and I was wondering if anyone of TDP could give me a simple tip if it's hardcoded or not. (Would prefer to avoid wasting my holiday time :D )
Greetz,

P.S.: Running on decoded files which are larger in filesize, perhaps that could have an impact?
I am not sure i understand what are you doing.
After you decrypted enc file to add whatever you want,did you repack it?
My client runs with decoded files.Originally Posted by emi
This is something that didin`t happens before,could you post some images?
Well then,
Here I removed some stuff I didn't need.
The client starts and the skill works.
Here I added some dummy stuff, just a copy & paste from an existing line.
And then my client crashes at loading.
Let me know if this is enough info.

Well what can i understand from that,ur cabal.enc run without to be encrypted,or what?
Yes it does. Makes things easier as I simply modify, save and execute without having to pack everytime.
Well i don`t know exactly,but you shouldn`t remove any linies from cabal.enc,you should left them,try another original cabal.enc with your custom dummy stuffs.
Have you tried testing it with a client that runs on encryted enc files ? Also I wouldn't do that for a public server if I were you, there are many ways you could exploit in a server by editing few enc lines.
I am fully aware you can hack quite a bit but I'm hosting for close and rl friends so it would be sad if one of them started hacking.
To topic, the lines I deleted were the lines from EP3 or 4 for items to have an aura at +15 as that simply does not work with our server files. If I added only half of the dummy lines it would still run so it was clear it had something to do with filesize.
Now what I didn't know and consulted my brother about (who modified the exe to run .dec's) is that the client first reads the .enc files and in the first 4 bytes it'll find the filesize if unpacked. Then it reads the .dec and if it's filesize does not match what it read in the .enc it'll error out.
I really should stop posting questions only to find the answer shortly after :/ (everytime, I search and search for hours, make a post and just a little bit later it hits me xD )
Apologies,
Speedy

Make sure you're not adding duplicate entries. CABAL doesn't like it if you use the same ID for multiple things :P If, however, it truly is a limit applied by a fixed array size, you might possibly be able to edit it. I've never personally tried increasing an array via odbg, before. However, I have a feeling it would cause issues (overlapping memory).
EDIT: Ah, yes. I came across the same issue when I was first experimenting with loading custom ENC's, back before *Phant0m released his (un)packer. Simply pushing the size into the register works (can't remember which register, though).

I thought that after making a topic for almost no reason, since I found the problem shortly after, I'd post some result. ^^"
After some mucking about it all worked out nicely. Still wonder about anicodes for skills. I added a skill id=464 but had to add the animation as SKIL2H_067 in the .ech to have an anicode=1201. I seem to be able to work around anicodes but I haven't yet found how they are determined.
Something along the lines of:
Sword skills: 1000 + ( XXX x 3 ) where XXX is SKILxH_XXX in the ech
Magic skills: no clue yet
But then as expected the anicode for 464 didn't work.
YouTube - CDev - new skill test
It's not that great a skill but it's taught me alot. Wasn't easy doing it all in hex, Yamachi's templates sure made it a hell of alot easier, kudos to you sir. Hope my next one will be better. (3D software with animation would rock tho)
