Actually I haven't planned a mod release, because there are some other tests and adjustments to be made. The problem is that I have almost no time and a poor machine (Pentium 4HT 3.0Ghz + Radeon x 1800) that barely allows me to launch the game, with epic loading times and frequent CTDs and/or BEX error (Buffer overflow Exceptions) that prevent me from doing my modding proprely.
I guess I could release a beta version as soon as possible, but I will need time for a complete release.
I'll keep you informed.
Anyway longam, you can do this yourself, it's very easy! It will take less than 10 minutes to modify all sim files for all 4 U boats (from VIIA to VIIC/41).
