Detailed Description

Customizable configuration data

This module provides a high-level abstraction around various features and settings which can be modified on the VMU. Many of these operations are provided by the Dreamcast's BIOS when a VMU has been formatted.

vmu_get_icon_shape()

int vmu_get_icon_shape	(	maple_device_t *	dev,
		uint8_t *	icon_shape )

Get icon shape of a VMU.

This function gets the icon shape of a specific VMU. The icon shape is a VMU icon that is displayed on the LCD screen while navigating the Dreamcast BIOS menu and is the GUI representation of the VMU in the menu's file manager. The Dreamcast BIOS provides a set of 124 icons to choose from.

Note

When a custom file named "ICONDATA_VMS" is present on a VMU, it overrides this icon by providing custom icons for both the DC BIOS menu and the VMU's LCD screen.

Parameters

dev	The device to change the icon shape of.
icon_shape	One of the values found in vmu_icons.

Return values

0	On success
-1	On failure
