How to get an errormessage when using the bat file?

[Kraxis]

So I used the unpacker and began to work suff over.

After a lot of changes to the ancilliary file I suffered crashes at startup. Obviously I had done something wrong, but what? Where was my mistake? I cuoldn't find out as I couldn't figure out to get a message of where the error lay. The old show_err could have been of use, but I can't seem to make it work.

So how can I change stuff without having to load up the game for every change?

Read the researchwiki on command line switches (https://forums.totalwar.org/vb/showthread.php?t=70892).

Also, this is the Tutorial forum, modding questions should be asked in the Modding Questions forum.

Aha... It just confused me... So I went all over the place and never seemed to be able to find the proper explaination. Oh well, I hope it works with the --io.file_first line... I better check it out.
