Manipulate rows 0–15, each 8-bit value. 6. Common Use Cases | Use case | How to use 8x16 | |----------|----------------| | Kernel terminal (bare metal) | Framebuffer + draw_char loop | | Bootloader text output | Use BIOS int 0x10 (VGA mode) | | Retro game (text mode) | Write to VGA memory at B800:0000 | | Linux framebuffer console | Kernel uses 8x16 by default (can replace) | | Embedded (SSD1306 OLED) | Draw_char with custom scrolling buffer | | Emulator UI | Software-render the bitmap into a window | 7. Alternative Formats & Tools | Format | Description | |--------|-------------| | PSF (PC Screen Font) | Includes magic header + Unicode mapping. Linux standard. | | BDF (Bitmap Distribution Format) | Human-readable, scalable to 8x16. | | FNT (Windows .fnt) | Old Windows 3.1 format, can be converted. | Alternative Formats & Tools | Format | Description
