mastervlad: All choices for the assasination attempt disable the Diktat, Claim Bessarabia and cede Quadrillateral. This is so I could remake those events inside the romania.txt in order to save space. The first option (no one notices) make for a generally historical game (so the claiming event still exist, except that the way war is declared is modified. Also Germany isn't allied with Hungary against Romania, Germany getting an option to choose what to do). The only one that sleeps all events for good is the Iron Guard choice, where Romania becomes a very important German partner early on, and thus it is protected from Hungarian and later Russian claims. Also the Soviet Union (in some circumstances), can renounce the claims on Bessarabia, in order to stage a coup (due to Romania loosing N Transylvania - I got this idea from a Soviet general who in 1990 said that one of the biggest mistakes the SU made before WWII was claiming Bessarabia, which threw Romania firmly into the German camp).
Actually a Romania allied with Poland and Turkey and possibly Greece and Yugoslavia, should last quite a while against Germany and it's allies, and is also quite probable, as the mutual defense pact in the region were still valid at the time. The problem is that I don't know how to make ai files, so a Comintern or Allied Romania in the war may not be as effective.
About music: yes in the music folder. There are txt files that determine which music is played when, so unless the mp3 files overwrite eachother, you won't loose the previous tracks.
jorian: The problem is that this mod is not completely Historical, because the 1936 assasination attempt didn't exist, there were serious ones before the timeline of the game, and one in 1938 (if I'm not mistaking), but that one didn't really have a chance to come out right. I may make a fully historical variant of the mod later on.
I still have to integrate a very important piece (the post-Barbarossa war - planned in 1941 actually), but school is not making it any easier.
