edit: long story short, I got R4, don't know which one, works on O3DS but some roms don't work. Want to update kernel/firmware but can't find them. Hello, I just bought an R4 and i don't know which one as it doesn't have a sticker anymore. It looks exactly like this one : And it's black or dark grey. Inside is a 4Gb Micro SDHC. It has a kernel and many DS roms. Here are the kernel files. Windows says it's from 2009. _SYSTEM_ folder _DS_MENU.DAT file -This R4 works on a DSLite (tested) -When inserted on my O3DS XL 11.3 Luma, it shows the cartridge of "Danny Phantom Urban Jungle THQ" -It works on my O3DSXL 11.3 Luma WITHOUT NTR Launcher but some games won't work (black screens, white screens, can't pass Nintendo logo, etc) -It doesn't work on my O3DSXL 11.3 Luma WITH NTR Launcher. When it does work, it goes like this -> white screen, black screen, upper screen says "loading...", white screen, black screen, main menu. The main menu looks like this: -upper screen is a calendar, at the bottom right it says in red R4DSi French -bottom screen is at top R4 Revolution logo (dark green color), two pacman for games, two music note for multimedia, Apple Finder Logo for Slot-2.Bottom left says 1.33 Does anyone have a clue on how I can upgrade my R4? I tried this : http://r4town.com/pages/R4i-Gold-Kernel.html None of them boot. Only "Wood R4i V1.64" gives me infinite "Loading...". Everything else is just black screen. With and without NTR Launcher. Thank you.
