well Rappo I got the game reinstalled and applied the GTA4 patch and got your Car Bomber working, but now I have a new problem, it seems to be unstable and only works when it wants to. I tried all 3 ASI Loaders available.
This ASI loader works with the car bomber but it lags my system to hell on performance, so that loader has issues alone
Alice and XliveLess don't hurt my performance and both work with the Car Bomber, but freezes and then crashes the game when mounting bombs, I tried about 2 or 3 different times with both of these loaders, sometimes I can only do up to 2 or 3 bombs, other times it freezes after just mounting 1 bomb
The fault might not be your mod, it could just be unstable ASI Loaders, or maybe a combination of both
Let me know if you need more testing done on a later release
