Well i have been playing a lot with the source code and managed to do this :
1.- Changed the way the key R works, increased simulation speed to 5x instead of akella 3x, and also added an extra button for 30x for quick navigations when needed, the only thing missing is to add this controls to configuration menu / controls area so anyone can change the key map inside the game.
2.- Improved the hole Usurer math so now is realistic and related to your $$$ habilities, suppose you invest $100,000, every month you can expect a return of 8,000 or more depending on our skills ( akella defaults were flat and useless )
3.- By default the sinking model of akella only works in 3D mode, it means that in map mode you can have 2% hull and not sink in 1000 years, so i fixed it, at 30% hull or less the ship will start sinking slowly at both interfaces 3D view / Battlemode / Map , and it will stop sinking until you repair above 30% hull, that means you need to rush for a repair if your hull is less than 30% , at 3D view interface it will show the sinking perk so you notice, suppose you had a nice battle and your hull is 22%, then you go to navigation map, you will have about 7 days ( Game time ) to repair , otherwise the map interface will send you to 3D mode when your ship is less than 2% to watch yourself sink.
4.- Based on the last sink rate, the ships will be shown immersed into water depending on the load and ship damage, this is just a visual effect that makes you feel how the ship sinks over the time.
5.- Managed to change the chances of cannon exploding ( it was high ) and tons of variables, the math is simple just need some testing.
I got used to the structure of the code so if anyone needs help finding some stuff or coding i can help.
