http://www.gamekool.com/images/R4SDHC.jpg This is the one I'm using. I remember messing around on my microsd, trying to get games to work, and when I put my card back in my DS, the games loaded as fast as lightning. I wanna know how I did that or if there are alternative ways to make games load faster. BTW, I'm using a 2GB PNY SDHC card.
There's an "ebook" folder with the files "FONTS.DAT", "FONTM.DAT" and "FONTL.DAT", a "themes" folder with the standard skins that come with the firmware , my personally made "CHEAT.DAT" file, and a "gbaframe" bitmap skin. That's it, what made it run faster? Ah yes, I am running on kernel v1.34 EDIT: I just cheacked my new firmware's files, and apprently it includes a "r4dldi.dat", "R4patch.dat", "savlib.dat", "system.ank", "System.fon", "system.l2u", "system.u2l", "usrcheat.dat", "YSMENU.ini", and 2 YSMenu skins.
Wait a sec... No. It is not possible anymore. I'm very sorry for you, but you will have to use R4_PANDORA.nds if you want fast loading speed.
