/* this defines the type of EEPROM inside the game cartridge as Backup RAM
*
* Here are some notes from 8BitWizard (http://www.spritesmind.net/_GenDev/forum):
*
* Mode 1 (7-bit) - the chip takes a single byte with a 7-bit memory address and a R/W bit (24C01)
* Mode 2 (8-bit) - the chip takes a 7-bit device address and R/W bit followed by an 8-bit memory address;
* the device address may contain up to three more memory address bits (24C01 - 24C16).
* You can also string eight 24C01, four 24C02, two 24C08, or various combinations, set their address config lines correctly,
* and the result appears exactly the same as a 24C16
* Mode 3 (16-bit) - the chip takes a 7-bit device address and R/W bit followed by a 16-bit memory address (24C32 and larger)
*
* Also, while most 24Cxx are addressed at 200000-2FFFFF, I have found two different ways of mapping the control lines.
* EA uses SDA on D7 (read/write) and SCL on D6 (write only), and I have found boards using different mapping (I think Accolade)
* which uses D1-read=SDA, D0-write=SDA, D1-write=SCL. Accolade also has a custom-chip mapper which may even use a third method.

This mode does not work on NTSC machines. All 30 rows of the name table are
displayed, there is no border, blanking, or retrace period, and the next
frame starts after the 30th row. The display rolls continuously though it
can be stabilized by adjusting the vertical hold.

Here are some details about what the different screen areas look like,
useful if you are emulating overscan or if you want to have a 'virtual'
vertical hold control in your emulator.
Active display - Where the display generated by the VDP goes.
Bottom border - Filled with border color from VDP register #7.
Bottom blanking - Filled with a light black color. (like display was blanked)
Vertical sync - Filled with a pure black color. (like display was turned off)
Top blanking - Filled with a light black color. (like display was blanked)
Top border - Filled with the border color from VDP register #7.
