I just got a brand new R4 from Volumerate and a new PNY 1GB Micro SD card. I read and follow the provided instruction (R4 English-1.11) as following: 1) Hardware Installation Connect the TF card to PC with the card reader, then, go to the "/SYSTEM" directory on the disk. A- Loading the game kernel: Copy the "_DS_MENU.DAT" at the directory of the simplified game kernel/ traditional game kernel to the root directory of TF card. B- Loading the media kernel: Copy the "moonshl" folder and the "_DS_MSHL.NDS" file at the "moonshell" directory to the root directory of TF card; C- Load the DIY interface: Copy all the folders "_system_" to the root directory of the TF card. 2) Unload TF Card After finishing ROM added, then right click the removable disk icon on the right down corner of the screen; Draw out the TF card from card reader/writer. 3) Main Menu Operation Connect the TF card to DS Slot-1 with the R4, turn on the power... However, nothing shows up, except my DS console welcome screen. No error message neither, nada!!! Should I format my Micro SD card for the first time use? Any ideas??? Thank you.
