Enum ExtendedConsoleType 

#[non_exhaustive]
pub enum ExtendedConsoleType {

Extended console type: NES 2.0 header byte 13, low nibble, when the console type (byte 7 bits 0-1) is 3.

Values per the Nesdev wiki’s “NES 2.0” page, §“Extended Console Type”. $0-$2 duplicate what byte 7 can already say and exist so a console-type variable can fold both fields together; they are kept distinct here so a header that uses them round-trips. $D-$F are reserved and kept in ExtendedConsoleType::Reserved.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Regular

$0: regular NES / Famicom / Dendy.

VsSystem

$1: Nintendo Vs. System.

Playchoice10

$2: PlayChoice-10.

DecimalModeFamiclone

$3: regular Famiclone with a CPU that supports decimal mode.

Epsm

$4: regular NES / Famicom with an EPSM module or plug-through cartridge.

Vt01

$5: V.R. Technology VT01 with red/cyan STN palette.

Vt02

$6: V.R. Technology VT02.

Vt03

$7: V.R. Technology VT03.

Vt09

$8: V.R. Technology VT09.

Vt32

$9: V.R. Technology VT32.

Vt369

$A: V.R. Technology VT369.

Um6578

$B: UMC UM6578.

FamicomNetworkSystem

$C: Famicom Network System.

Reserved(u8)

$D-$F: reserved. The value is the nibble itself (13..=15).
