How to make a custom made client program

[clarisalene]

Does anyone know how to make a customized client program? My client program does not playing any BGM and sound whenever I'm going to open it at first. Please teach me also how to make the client that will corresponds to rathena's settings such as packte_db_ver and other settings to avoid errors such as CHARACTER_INFO SIZE:.

I will appreciate all of your help and thank you sharing your knowledge how to run rAthena server. More power to all of you

Match client date with the date defined in #define PACKETVER, src\common\mmo.h.
