While standard DS emulation is relatively straightforward, the DSi (Nintendo’s "enhanced" handheld) added layers of hardware and firmware complexity. To get these games running on modern devices, you need the original system files. Here is everything you need to know about dsi_bios7.bin , what it does, and how it fits into your emulation setup.
