Everybody knows that MT-card emuNAND can be partially upgraded: - Download latest firmware with 3DNUS - Replace the latest menu/mint/mset/tiger with 9.4 ones (otherwise emuNAND will blackscreen) - Use BigBlueMenu to install all the rest CIAs But since menu/mint/mset/tiger are not the latest version, the update nag will be downloaded normally. I tried spoofing 9.4 menu/mint/mset/tiger to make the system recognize them as 10.5 ones, for expecting it could remove the update nag: (Thanks somebody in GBATEMP who introduced this spoofing method.) - Open 9.4 menu/mint/mset/tiger CIA with Hex editor - Change offset 0x2F90 0C-0D values (they are in Hex) to 10.5 menu/mint/mset/tiger's values (You can find the values on 3dbrew.org, but they are in Dec, you need to convert them to Hex manually) - Overwrite installing modified CIA with FBI (menu cannot be overwritten) But unfortunately the result is - emuNAND blackscreens. That means this spoofing method doesn't work for MT-card emuNAND. ----------------------------- BTW, this spoofing method works for SysNAND 1.1.0 exclusive Promotion Videos (0004001000023000/24000/25000) installing to emuNAND. It also fixes "Cannot install the video in same region" issue. To be noticed that "different region video" need RegionFree-enhanced system (GW/rxTools) otherwise they will not be displayed (Rei/Cakes). - Open the Video CIA with Hex editor - Change offset 0x2F90 0C-0D from 00 00 (v0, USA/EUR) or 00 02 (v2, JPN) to 08 00 (v2048) - Normally install modified CIA with BBM/FBI Haven't tried installing spoofed 1.1.0 videos to SysNAND though.
