I have noticed that R4iRTS MoonShell2 reset launches /loader.eng. So I had an experiment to apply it to general purpose kernel switcher. http://www.mediafire.com/file/jhjdlxlmmwx/M3R_R4i_r7.7z How to install/use: Put all files to your TF then launch /_system_/*.nds from anywhere. Below are useful utilities: http://filetrip.net/f9907-M3-Kaura-Language-Builder-1-0.html This is M3 Kaura lng file builder (I analyzed format). Why I made this? I wanted to localize to Japanese. JP932.lng is built with this. But there is a issue: JP932.lng isn't usable until you copy inside of /SYSTEM/font/CP936/ to /SYSTEM/font/CP1250/. http://www.mediafire.com/file/nmzwizzgewz/m3dec.7z This is m3dec(kernel header decrypter)/m3patch(card check interceptor). Once ago, Rudolph made M3R_iTDS_PP2 to patch M3 kernels, but I felt it is not so good for batch scripting. So this program decrypts header automatically. Also, patch files are very small. How to upgrade R4i: Put R4i.sys in the same folder as m3dec then launch SakuraMultiBoot.bat. As I have made m3patch, I'll remove the vbs from M3R_R4i in the next release. Done.
