BIOS Setup

In order to have better game compatibility, NeonDS version before 0.1.0 requires the original NDS bios files. Please search and download the bios files and put the two bios files in the same directory as NeonDS.exe and named as "bios7.bin" and "bios9.bin".You'll get the files like the following picture shows:

DirectX setup

Before trying to run NeonDS version before 0.1.1, please make sure you have the newest version of DirectX9 installed. If the directX version is not so up-to-date, you may get error message complaining missing dll file "d3dx9_31.dll". In such case, you can try search and download this file from your favorite search engine and put the file in your system driver "windows\system32" directory.
