Dear all, last month I try to make a CFW for 2DS Pokémon Limited ( JAP ) and now everything work well with Luma3DS 9.2.0-20j or update to 10.7.0-32j. Thanks all for kindly support me ^^ Now I found that many USA game have a problem (enter game and then ruturn to Home menu) to run without choose config "Enable region / language emulation" of Luma3DS setting along with .txt file for each game in "locales" folder of luma in SD card. Now I try to change EmuNand region from Japan to USA to solve this problem, but all failed with black screen after Install and inject SecureInfo_A_usa. Here's my method: 1) Download firmware 9.2.0-20U by 3DNUS and put to folder "updates" in SD card. 2) Use BigBlueMenu ( or SysUpdate ) to install all .cia file in folder "updates". 3) Restart and launch Decrypt9WIP form HBL to inject SecureInfo_A_usa from EmuNand option. 4) Boot into EmuNand by Luma3DS ( also try CakesFW ) but black screen ( wait for 5 minutes ) Please kindly give me any advice T^T, thanks in advance.
