The dialog consists of a list view that shows the current memory configuration. Each row contains one RAM mapper, ROM mapper or I/O mapper configuration.

The list has five columns. The first column indicates whether the mapper has any conflicts with any previous mapper.

In the picture above one mapper is placed on the same slot, subslot and address as a previous one and thus causing a conflict. The conflict can be resolved by changing the address or slot configuration of the mapper.

The meaning of the other columns is as following :

Slot		Slot and subslot number where the rom shall be mapped. A mapper can be unslotted in which case this field is blank.

Address		The address where the ROM/RAM shall be mapped. If the mapper is unslotted, the field is blank.

Type		Specifies the memory type of the mapper.

Rom Image		Specifies the ROM name if the mapper is a ROM mapper.

Below these columns, there are three buttons :

Add...		Adds a new entry to the memory configuration list.

Edit...		Edits the selected entry to the memory configuration list.

Remove		Removes the selected entry from the memory configuration list.

When the Add or Edit button is pressed or if you double click on a mapper entry in the list. A mapper configuration dialog is shown :

The dialog contains five fields :

File		The field shows the selected ROM file for the mapper. The button opens a file dialog where you can select a ROM file for the mapper. If the mapper does not require a ROM file, this field will be disabled.

Type		A dropdown list where the type of mapper is selected.

Slot		Specifies the slot where to map the ROM. If the type is an I/O mapper, this field is disabled.

Address		Specifies the address within the slot where to map the ROM. If the type is an I/O mapper, this field is disabled.

Size		If the mapper is a ROM mapper, this field shows the size of the ROM. If the mapper is a RAM mapper, this field is an enabled drop down menu where you can set the RAM size.
