Mahjong game

Hello Please someone from Japan I need game developers from China, to install a plugin to my game This game is a mahjong game and I need you to make a plugin for this game in my picture. 1. so that I can see my opponent's tiles. 2. so that I can see the tiles in my library. 3. so that I can change the tiles in my hand at will during the game, (of course, this is on the basis of having inventory in the library). I don't have the source code for this game, so you need to get the source code first, and then make the plugin for me. Here is the link to download his site: [login to view URL]
