So I've done again a little back reading on Retrogamefan's thread and I seem to have finally have some idea about the "date lock" you guys are talking about. Unfortunately, this is something I haven't experienced since my R4 clone card is the 2017 versionI just want to clarify something @BARNWEY , your guide's goal is to bypass the "date lock" with the original R4 clone kernel and make all Dsi-enhanced games be compatible with Ysmenu right? I tested your guide on Pokemon Black Version 2 but it still doesn't work using YSmenu. I still have the same issues. I do have a few questions though:1. Step 3 says that I load all my DSi-enhanced games in the original R4 kernel. So does this mean all the .sav files are created in the R4 kernel?2. Step 12 mentions that if ever there are no .sav files for a DSi-enhanced game, I should create it with YSmenu right? Doesn't that defeat the purpose of Step 3? Hmmm...3. Assuming I got Question #1 right, when I start a Dsi-enhanced game in YSmenu, the .sav file that will be used is the one created in the R4 kernel right?
