On Linux and macOS, file names are case-sensitive. The emulator expects dsi_bios7.bin (with an underscore) or dsi bios7.bin ? This varies by emulator version.

Emulators, which are software programs that mimic the behavior of a console, often rely on exact copies of these BIOS files to function accurately. Without them, an emulator might have to guess how the original hardware behaved, leading to poor performance, graphical glitches, and frequent crashes. That's why files like dsi_bios7.bin are indispensable for a high-quality DSi emulation experience.
