Hello Rezi, and thank you for trying out MabiPro
We hope you have a wonderful experience here.
Here are the answers to your questions.
1)There is no IP restriction in MabiPro, everyone is welcome to play and try it out.
2)You will need the MabiPro client to log in to our server.
3)The server files that was leaked was based on a Japanese production computer. English files was not found. So a majority of the NPCs and Quests are in Japanese. However we are looking forward for people translating for us.
4)It does not get updated any further because NXJP has patched the issue that caused the leak back in 2010.
5)Additional Features is what we can certainly edit and add to the game. If we cant' do it then it's most likely because it's a hard coded feature, however this does not limit us to adding in custom content. We're able to add items, create custom dungeons/shadow missions, create custom events and NPCs. Just recently I added an item that you can equip on the accessory slot that plays any special effects in the game. My favorite item is tamed special effect, where the orange swirl runs around your head. These items will soon to be released in the Fall Season Gachapon, which I am certainly working at implementing
6)It is true that the Pre-Gen is more lag-friendly then the Gen. However if you do experience bad latency we have 3 nodes that you can connect for each channel. To connect to a new node just simply change channels.
If you want to determine your latency. I highly recommend you ping the domain login.mabi.pro manually via the Command Prompt
to do this, press WINDOWSKEY+R and type in cmd, you will see a black screen, then type ping login.mabi.pro
you'll want to look at the "time" string. Based on the value you get this is how your experience will be.
0~59ms = Excellent
60~199ms= Good, you may have a minor delay
200~399ms = Caution , you may have delays
400~600 and higher = Poor, heavy delays will occur.
7)If you see me in game, I can show you how that works. However don't be afraid to ask other people here too, we have a global chat that can intensively help you out as you progress further in the game.
8)We don't have CP mods or anything, but the creator of abyss did create a patcher for our version, you can see his work
