Syscall index: 0x0D08
Function signature: void Bdisp_MMPrintRef(int* x, int* y, const char* string, int mode_flags, int xlimit, int P6, int P7, int color, int back_color, int writeflag, int P11);
Draws a line of text on the VRAM with the 16px Font, used for app names in the Main Menu. Very similar to Bdisp_MMPrint (which is a wrapper around this function), but the coordinates are passed by reference and update as the text is drawn, which may be useful in some situations.\
- int* x - Pointer to an integer containing the position of the text on a horizontal axis, in pixels. It is automatically updated to the position for the next character as the text is drawn.
- int* y - Pointer to an integer containing the position of the text on a vertical axis, in pixels. Automatically incremented by 24 pixels (status area) unless mode_flags is set to 0x40.
- const char* string - The string to display. Certain multi-byte characters are supported.
- int mode_flags - controls whether to clear text background, or
invert background and foreground colors:
- 0: normal text mode
- 1: swaps color and back_color (the foreground color becomes back_color)
- 2: transparent background mode; back_color is not used
- 4: inverts colors (so red becomes cyan, blue becomes yellow, etc.)
- 0x40: allows for drawing text on the status area
- One can combine at least some of these flags (with a binary AND). So if flag 1 and 2 are set, this function draws only the text background in back_color, leaving the foreground untouched (transparent)
- int xlimit - Upper horizontal limit - text will be cut past this point. Set to 0xFFFFFFFF for it to be ignored.
- int P6 - Still unknown, set to 0
- int P7 - Still unknown, set to 0
- int color - The color of the characters
- int back_color - The color of the characters’ background. Depends on mode_flags
- int writeflag - Set to 1 for the text to be actually drawn; setting to 0 only makes the value of x update as if the text was being drawn.
- int P11 - Still unknown, set to 0
