I have bought a clone R4iSDHC, based on DSTT. The game info library file name is GAMEINFO.DAT. Now the kernel of this cart is not updated for a long time. So I must find to use a self way to update it. But I download the newest DSTT infolib.dat. And renamed to GAMEINFO.DAT and override it. Then, all the games will start white screen. What's the hell?
