Shopping Mall

Not really sure how did I used to do this, but here it is
1- Redux\bin\Debug\ini - Find Shop.dat.
2- Ctrl+F " VIPSHOP ".

Spoiler

3- Add " Item66 = Item ID ".
4- Increase ItemAmount EX." ItemAmount=68 ".
5- Do the same with the Client Shop.dat.
6- Add the items into the database table Shops under it's own ShopID which you gonna find by yourself because I'm totally lazy to search about it, but you could simply find it with a unique item ID which listed only into the Shopping Mall, I guess you could easily understand where it going now.

Here's a tool you could use to make it easier for yourself to manage Shop.dat released by Pro4Never - the topic link is [Only registered and activated users can see links. Click Here To Register...]

You can also remove the item by the same way you add it.
