I give up for today ^^'
I have deleted the game and downloading a new fresh one to be sure to have a clean file.
For resuming before retry:
-> i put JSGME in main file
-> i put "100_FalloftheRisingSun_Ultimate_v1.8" inside the "MODS" file created by JSGME
-> i turn OFF "read only" for all Silent hunter File
-> i On "Windows 7 compatibility", "diseable Full Screen Optimisation", "Run programe as Admin" and "Higth Scaling DPI" for SH4 executable.
-> Use JSGME to activate only "100_FalloftheRisingSun_Ultimate_v1.8"
[ I have to use the 100% text and app scalling on my computer beacause the game can't start (vanilla or not) when it's turn to 125% (recommanded)]
[My resolution was 1920x1080 (recommanded) and the same option in the game]
Thanx all for help!!
