I did a little tweaking in SH3 myself and for changing equipement and/or availability of the different submarines you had to change the basic.cfg file in the \data\cfg folder.
Searching through the game files of SH4 I stumbled over the same files in SH4 with the "original" SH3 content.
Are they still in use or what do they do in the SH4 \data\cfg folder?
Is there a file like this in SH4 too?
I just want to do a bit of tweaking for SH4 and I started with the minitweaking-utility but haven't found out anything about equipment or availability dates.
Thanks in advance and just dive safe mates!
