User:Zzo38/Metadata INI

You can have a INI file, with the .nes.ini (or .unif.ini or .fds.ini or .qdi.ini) extension, to describe preferred controllers and other information about a game other than what is in the ROM image file. Anything in the file not understood by whatever program is reading this file, should be ignored. Everything is optional (both for writing and for reading; different blocks may be meaningful for different programs that would use this information).

If numbers are expected in a value, they are normally decimal, and can be hexadecimal by 0x prefix.

(Note: For QDI format disk images, the INI file must correspond to the file for the bootable side.)

Blocks

Main

Title

The title of this game. This does not have to be the same as the title in a UNIF or mapper 768 ROM image file.

Author

The name of the author of this game.

URL

URL to access information of this game. Any URI scheme is allowed, but file:/// and LAN addresses is not recommended for files distributed on the internet.

Version

Game version number.

TV

Specify the TV mode supported, separated by vertical bars if there is more than one.

• NTSC: NTSC Famicom or NTSC NES.
• RGB: RGB Famicom.
• PAL: PAL NES.
• Dendy: Dendy PAL Famiclone.

License

Specify if the game is officially licensed.

• Official means it is licensed by Nintendo.
• Unofficial means that it is not licensed by Nintendo; for example, anything published by Tengen, Codemasters, or Color Dreams, or homebrew software.

CRC

Specify the CRC32 checksum. If it doesn't match, it is error.

Bootgod

The ID number for the game in bootgod database. Emulators should not use klugy hacks to work with specific games if the INI file exists and does not have the Bootgod entry specified.

Text

Absolute address into ROM image file of a null-terminatd text. It is not required for UNIF, although it is still allowed.

PPUID

The low five bits of the value which should be read from $2002. Normally this is read from the NES 2.0 header, but in case that is not available, it is specified here.

Controller

Players

Tells how many players. Can be 1, 2, 3, 4, or can be multiples separated by vertical bars.

Player1

Specify the device connected to the first NES controller port. You can have multiple values separated by vertical bars; it can also be blank entries meaning nothing is connected.

• Standard: The standard controller of NES/Famicom.
• DoubleFisted: The standard NES controller, rotated 90 degrees with the Control Pad at the top and A at the bottom like a Wii Remote.
• Mouse: Super NES Mouse.
• LightGun: Zapper.
• Arkanoid: Arkanoid Vaus controller.
• SuperNintendo: Super Nintendo standard controller.
• SuperPakPak: Super PakPak analog controller.
• VsSystem: VS System. Player 1 VS system controller must be specified in the player 2 slot and vice versa.
• VsLightGun: VS System serial light gun. Player 1 VS system controller must be specified in the player 2 slot and vice versa.
• PowerPad, PowerPadB, FamilyTrainer, FamilyTrainerB: Power Pad B side.
• PowerPadA, FamilyTrainerA: Power Pad A side.
• PowerPadLeft, FamilyTrainerLeft: Power Pad B side, rotated by 90 degrees so that the encoder is at the left.
• StandardDDR: Dance mat which is using the protocol of the standard controller and allows Left+Right and Up+Down presses. Used by some NOAC-based dance mats.

Player2

Specify the device connected to the second NES controller port. They are the same as Player1 devices, except for the following:

• Standard: Does not include SELECT and START buttons.
• StandardSelectStart: Does include SELECT and START buttons.
• StandardMicrophone: Uses the microphone.

Player3

Used if Expansion=FourPlayers or FourScore=Yes is specified. Must be a controller that uses D0 or D1, not D3-D4.

Player4

Used if Expansion=FourPlayers or FourScore=Yes is specified. Must be a controller that uses D0 or D1, not D3-D4.

Expansion

Specify the device connected to the Famicom expansion port. (In case of some devices that work on Player2 or the expansion port, it can be specified either way.)

• Keyboard: Famicom keyboard.
• OekaKids: Oeka Kids tablet.
• KeyboardTape: Famicom keyboard and tape recorder.
• FourPlayers: Four players game. The Player3 and Player4 fields specify the controller for player 3 and 4 whose D0 is connected to the Famicom's D1.
• LightGun, FamilyTrainer, FamilyTrainerB, FamilyTrainerA, FamilyTrainerLeft: As above.
• ExciteBoxing: Exciting boxing.
• Mahjong: Mahjong.
• Stereovision: Famicom 3D glasses.

FourScore

Specifies if NES Four Score is used. Values can be No and Yes. You can have multiple values separated by vertical bars.

If Expansion=FourPlayers or FourScore=Yes is specified, the Player1, Player2, Player3, and Player4 indicate device connected to the adapter (such as Standard, DoubleFisted, or StandardDDR). Devices using D2-D4 won't work on either adapter, and devices using a long report, such as the Super NES Controller and Super NES Mouse, work only with Expansion=FourPlayers, not FourScore=Yes. If a game specifies both a four-player adapter and a peripheral incompatible with the adapter, the emulator must provide a way to switch between the adapter and the other peripheral.

License

Name

Name of a software license.

FreeSoftware

The value can be No and Yes. Specify if it meets the Free Software definition (from FSF).

OpenSource

The value can be No and Yes. Specify if it meets the Open Source definition (from OSI).

Usually this value will be the same as the FreeSoftware value, but there are some exceptions.

PublicDomain

The value can be No and Yes. Specify if it is effectively public domain (e.g.: public domain, WTFPL, Unlicense, CC0).

Mapper

Information of mapper.

Name

Name of the mapper. You can have multiple values separated by vertical bars.

Number

The iNES mapper number (0-4095), optionally followed by a dot and the submapper number (0-15 or A-F). If no submapper is specified, submapper 0 is assumed. You can have multiple values separated by vertical bars. If used with NES 2.0 format ROM image files, at least one of the numbers listed here MUST be the same as in the ROM image file, if this line is used at all. In old iNES files, it is probably going to be the same, although in some cases it might not be (these cases are fixed by the NES 2.0 format).

NumberEx

Specifies extensions to the mapper which are not necessarily relevant for emulation. You can have multiple numbers separated by vertical bars, but usually you won't, since you will only specify the features actually used on this mapper (some games might have been released with multiple mapper settings though, for some reason).

This is a sixteen-bit number. Its meaning depends on the first iNES mapper number specified in the Number; the low four bits have the same meaning as submapper numbers.

Mirror

Set the mirroring. You can have multiple values separated by vertical bars.

• H: Horizontal.
• V: Vertical.
• 1: One screen.
• 4: Four screen.

RAM

Specify the amount of PRG RAM used in the cartridge, in bytes.

BusConflict

Specify if bus conflict is used. You can have multiple values separated by vertical bars.

• No: Require not bus conflict.
• Yes: Require bus conflict.

Audio

Use of expansion audio. Can be No and Yes.

Verilog

Version number of Verilog and/or extension of Verilog in use. You can have multiple values separated by vertical bars. This is only for use with mapper 768 submapper 1.

Switch

This block specifies the name and default settings of VS Unisystem switches. The names are given by Name0 to Name7, and the default value is given by Default0 to Default7 which have the values 0 and 1.

Emulator

Specify klugy features of specific emulators. The key is the name of the emulator; the value is not described here.

Hardware

Specify what NES/Famicom hardware and hardware clone it is tested with. The values are:

• Work: It works.
• NotWork: It doesn't works.
• Partial: It works partially; probably it is good enough.
• Untested: It is not tested.

The keys are (not limited to):

• Nintendo: The official hardware from Nintendo. (It ought to work!)

EmuTest

Same as the Hardware block, but for emulators. You can also specify version numbers in this block, separated by vertical bars.

Tag

Miscellaneous metadata for use with search engines.

File

This block indicates what files are included, and what purpose of the files. The keys are the filename, and the values specify what they mean. You can have multiple values separated by vertical bars.

• ROM: ROM image file; usually implied (so is not needed).
• Documentation: Documentation in HTML, XHTML, DocBook, DVI, DjVu, PDF, PostScript, or PCL format.
• DocumentationASCII: Documentation in plain ASCII text. (This is separate from the above since plain ASCII has no "magic number" to detect, unlike all the above formats.)
• MetaFont: METAFONT file for fonts used in DVI.
• SourceCode: Source codes.
• Disk: A disk image (in QDI format).
• Icon: Icons for use with iPhone, Android, etc.
• License: License file (normally in plain ASCII text).
• ADPCM: ADPCM waveform data for expansion audio.
• Label60: Label for 60-pins cartridge.
• Label72: Label for 72-pins cartridge.
• Boxart: Box art.
• BIOS: FDS BIOS ROM. (Normally there is no need to use this type even for FDS games, since the BIOS is not normally included with the disk image. However, it might be helpful in some cases.)
• Palette: Recommended RGB palette data (for RGB mode only). It is not necessarily going to be used, but it can improve the color slightly.
• Enhance2xCHRROM: Double-resolution CHR ROM for enhancement.
• EnhanceData: Miscellaneous files for enhancement, refer by other files such as cue files.
• EnhanceAudioCue: Cue file for telling what sounds to play when values are written to RAM.
• EnhanceTiles: File containing full-color tiles mapping to CHR ROM bank/attribute pairs. (TODO: Specify format of this file.)
• InstrumentsFM: File of exactly 120 bytes containing OPLL-format FM instruments numbered 1 to 15.
• SaveGame: Default initial contents of battery RAM.

Memory

Specify the memory mapping of the ROM and RAM for this game, for purpose of debugging, cheat codes, ROM hacks, etc. (TODO: need to specify details)

Enhance

This block lists enhancements that might be used in some emulators (the emulator should offer an option to turn them off, even if they are supported, though). Some may work on hardware too, but that does not usually affect the cartridge, so this block is probably not used when loading on hardware.

PopReduction

Values can be No or Yes. You can have multiple values separated by vertical bars.

CueAudio

Values can be No or Yes. You can have multiple values separated by vertical bars.

PointingDeviceRAM

This is used to write the coordinates of a pointing device into RAM. There are multiple values separated by vertical bars, as follows:

• RAM address for X coordinate.
• RAM address for Y coordinate.
• Leftmost coordinate.
• Rightmost coordinate.
• Topmost coordinate.
• Bottommost coordinate.

SpriteLimit

Values can be 8, 15, or NoLimit. You can have multiple values separated by vertical bars.

8

Normal sprite evaluation. Clear secondary OAM in 1-64, evaluate starting at 65, fetch patterns every 8 dots starting at 261.

15

Optimized sprite evaluation. Clear secondary OAM in 1-30, evaluate starting at 31, fetch patterns every 4 dots starting at 261.

NoLimit

No limit of sprites on one scanline. If evaluation or fetch overflows the allotted time, mapper side effects are disabled until it completes.

HighScore

This is a list of RAM addresses separated by vertical bars, which store high score data. The emulator might choose to somehow make them persist, or to do other things with it.

ScreenMode

Values can be Normal, 2xCHRROM, Tiles, Overlay2xPPU, Super2xSaI, Scale2x, or hq2x. You can have multiple values separated by vertical bars.

GameGenie

Contains unencoded Game Genie codes. The keys are the name of the code, and the value are one or more 32-bit numbers separated by vertical bars (normally written in hex format, with 0x prefix).

• Bit14-bit0: Low 15 bits of address. High bit is always set.
• Bit15: Set if this is a compare code.
• Bit23-bit18: Value to read from that address.
• Bit31-bit24: If it is a compare code, the value will not be changed unless it matches the value placed here.
