Page to note down ideas. Not necessarily an official plan.


Item Status
Various suggestions from retool author unexpectedpa - read them/sort into todo items:


Time Period Category Item Status
Interface Page should be responsive, not fixed-width.
Interface Search bar on every page, that can search titles+hashes+serials for every system (like redump)
Interface Solicit feedback/help on the DoM sidebar?
Interface Keep users logged in for longer
Interface Login box at top of page Done
Interface Remember last page/system/search-settings Partially done - DoM remembers the last system for logged in users
Interface Line-up languages on archive edit page - they look wonky
Interface Add option to group items together in the News section like on mediawiki. E.g. if a single user does a bunch of edits on a single system, that would be displayed as a single entry like "100 edits by x in SNES" (you'd click on it to go to that system's news page to see the details)
Interface For Trusted Dump sources, highlight if the dumper is set to !unknown/marked as unconfirmed, or if dump tool is blank/set to !unknown
Database Put more stuff in parameters in URL (e.g. for search) so that more stuff can be linked to
Database Each archive and dat (at least) could have a GUID, and pages should be accessible via URL with that ID, so that database entries can be referred to by third party projects (like Wikidata), without there being a risk of the ID changing. Also, this would allow ROM managers and emulators to identify DATs easily.
Database Locked DATs should still be viewable.
Database It would be more efficient for the user if all forms (archive, source, file, attachment) were all on one edit page
Database "Extra" (user-specified) fields like the archive has would be useful for sources and files too
Database If an archive only has some files MIA, then the tag in Search and the top of the archive page should say "Partially Missing" or something like that, not just say "Missing".
Database DAT files could be cryptographically signed so people can tell if reuploads of the dat files are genuine. Probably best to include a text file with the filename, size in bytes and sha256 of each file in the download, and then sign that.
Database Dynamic cue generation/download for Non-Redump dats
Database Create new homepage design, including easy-to-use undumped list/database lookup tool There is a new homepage design, but it could maybe do with some explanatory text based on the old one, although maybe on a secondary page. Hiccup has a draft of an improved version of the old text.
Database A new, modern, database should be developed, probably best doneas an open source project.
Database Exclude the header skipper tag in the dats by default Done
Database Add form to search for a all edits done by a user
Database Allow updaters to edit (but not delete/create/rename) Extra fields Done
Database Include more fields in the DATs, like additional tag, proto etc, license status, so people can filter stuff out client-side/using ROM managers
Long-term Database Allow customised daily packs (same options as with individual packs)
Database Maybe create ticket section for generic/whole-of-DoM tickets?
Database Add an option to see preview of datfile changes/result before saving archive/source/file changes
Database Add some way to find archives that don't have any sources with cart and/or pcb photos
Database Add option to mark dumper name as unconfirmed, like with dump date
Database Add option to mark attachments as missing/wanted (e.g. mark PCB photos as missing, if they haven't been provided). Probably should have deafult values for each dat. E.g. with SNES pcb would be flagged if missing, but not for DS.
Data Import/Export Create a YAML/YAML-like format for submissions in forums, as an alternative for the formats people end up "making up"
Data Import/Export Create a script that datters can use locally to convert the YAML format (or just variable human-readable text format) into the DoM import XML
Data Import/Export Make import XML support all DoM fields and use names consistent with those DoM fields
Data Import/Export Create schema for import XML Done
Data Import/Export Use same XML format for export (instead of the "plain text" format that doesn't have all the fields) Done?
Data Import/Export Create API to allow specific data to be retrieved/added to DoM:
  • Allows emulators/dump tools to interact with DoM
  • Check ROM status
  • Submit data directly
Simple API to check ROM status via hash is likely
Data Import/Export Change-request system. I.e. Datters could accept/reject/edit/add comments to submissions by non-datters (maybe even people without logins)
Data Import/Export Allow CSV import/export
New Database Fields All fields where people use commas to separate values should probably be split into multiple fields?
New Database Fields Scene releases should have a Region field, like "normal" sources. Done
New Database Fields Maybe add faster hash types. E.g. BLAKE3 (cryptographic hash, faster than SHA256 but less common) or xxhash (even faster but not a cryptographic hash).
Input Validation Some formats should have certain file extensions and vice versa. E.g.:
  • N64 - BigEndian = z64, ByteSwapped = v64.
Input Validation Game serials generally follow a certain format.
Input Validation There is generally a fixed list of PCB serials for each system.
Input Validation Some sizes are invalid (or unlikely) for some systems
DAT Generation Add the DAT IDs to the daily pack, so ROMVault etc can identify dats between renames. Done
DAT Generation For Nintendo CDN dats, include the digital serial fields' values (i.e. the Title IDs) from the source(s) Done?
DAT Generation Add category tag like redump, but with support for multiple categories Done
DAT Generation Add option to download daily pack with just numbered/just unnumbered dats.


Item Status
Create script to convert CSVs to the XML import format


Item Status
DAT Notes and the "Convention" pages overlap a bit - some stuff should be combined
Make video tutorials for DoM and put them on the wiki somewhere



Item Status
Check for ROMs that are in DoM but not in the Nintendo lotcheck sheets/DSi whitelist to find the "blind spots" of the lotcheck sheet/DSi whitelist (e.g. non-Nintendo-manufactured games / games post-2013ish and DS games that uses the newer encryption, respectively)
Work out the best way to do "modifications"/"alt formats". Currently dats use a mixture of having "trusted modification" entries (which have the issue of modified files not being able to be matched to the original files, except manually by reading comments) and just having alt formats (which are ambiguous as to who did the modification/when and its unclear if all sources should have the alt format or not. Examples of relevant dats: ique/wii/dsi/3ds/wiiu/switch digital, nes, n64, fds, ds, dsi, 3ds, switch.
Move stuff from undumped lists to DoM
Standardise the dump tool names - currently there is lots of variation
Catch up with dump submissions on the forum
Catch up with corrections on the forum and in the DoM tickets
Transcribe cart serials from photos, for sources where this is not already one
Look into this, it maybe be useful
For entries with PCB front photos, compare the sizes written on the ROM chip(s) with the ROM dump size
If the dumper says what dumping settings they used (e.g. what mapper the dumping tool is "dumping the cart as"), which they should do, then make sure that info is put into the comment2 of the DoM entry - go back and look at "Added to DoM" forum posts (e.g. ones using recent FlashGBX versions) and add it.
Might be worth putting torrentzip (RV7Zip?) hashes for every file - that way compressed data can be checked against dats without having to decompress or rely on crc32 in zip/7z headers (although maybe zip formats should just move to sha256 or something in their headers)
Create a tool that analyses overdumps to determine true ROM size and maybe require making overdumps and using the tool for all future dumps.
Make a list of dats where FilesOnly mode in RomVault should be used, i.e. dats that contains zips (and other archives) "as roms". At some point this could be integrated into DoM/the dats themselves.
Add bad dumps to the undumped lists so there's an easy overview of the high-priority items
Myria: "INL retro dumper gets different data "past the end" from beyblade versus gba_backup_tool. this is due to a phenomenon called "open bus" and electrical differences between the INL dumper and a nintendo DS." - this could potentially be simulated by specialised dumping hardware (or even software?) to determine when the real ROM ends.
Add categories to all archives using the new category field. Most can/should be automated somehow.
Revert changes where homebrew released worldwide on the web had their region changed from "World" to "Unknown" or "Unset" for no clear reason (note that latter tag has no documented purpose).
Add support for license and life span filters to the daily pack, and configure it so that homebrew and aftermarket ROMs are set to "off" on the individual and daily pack download pages by default
Make a script to compare GordonJ's ROMVault MIA dat (MammaMIA) with the DoM Daily Pack MIA values and run it every so often
Run MAME's romcmp tool to check ROM sets for common error patterns
Make a Neo Geo section These checksums can be used as a base:

Lotcheck sheet ROM size comparison

Do comparison, then update DoM entries with incorrect sizes as appropriate.

Batch-adding SHA256 to files

Item Status
NES Done for non-excluded files
N64 Done for most/all non-excluded BigEndian files


Item Status
Add headered format so ROMs in that format can easily be matched with the dat.


Item Status
Create GodMode9 script to automate dumping a bit


Item Status
For revisions that are not confirmed to exist, it may be possible to de-confirm them by finding a cart that was manufactured after some of them by finding an unrevised cart that was manufactured after the revision's "ROM release date" on the lot check sheet. The manufacturing date could be determined by the date on the ROM chip (if there is such a date) or the date on the back of the PCB.
Find a way to dump the undumpable area at 0x1000. Its present in Wii U Virtual Console dumps and allows the header CRC16 to validate if present. Its difficult because DS carts use an ASIC (or something like that).
Compare the header/code hashes from the DS cart whitelists (from DSi and 3DS consoles) with the hashes generated from a fullset.
Fully document all the DSi whitelists and other built-in gamecart lists here:

DS firmwares: work out what determines the colour/behaviour when the gamecart is removed while PictoChat is open


What is known (or sort-of known):

  • IPAs downloaded by iDevices are "thin" IPAs, meaning they only work on their processor architecture. While IPAs downloaded from iTunes are "fat" IPAs, meaning they contain code for all supported architectures.
  • "On-Demand Resources" (i.e. run-time downloads) will be difficult to preserve properly.
  • IPA files can be downloaded from itunes on PC/mac, including old versions. Some unlisted apps can be downloaded, as long as they were in your library, some unlisted apps won't let you download them, even if they are in your library, some unlisted apps will be gone completely from your library.
  • IPA files are zips, and the zips themselves contain metadata in the form of last-modified dates. Not clear how timezones play into this.
  • Before download, the server encrypts the code in the IPA with a key tied to the Apple ID and unique values
  • The apps are installed by extracting the IPA to the iDevice filesystem. The dates from the ZIP are possibly preserved, although its not clear how timezones play into this.
  • There are tools for jailbroken iDevices that can decrypt the code of a running app.
  • The code is signed by the developer and apple. The code contains hashes for at least some of the other files in the zip


Item Status
See if timestamps are preserved when an IPA is installed.
Try out different jailbreak apps for decrypting IPAs
See if the code is still signed by the developer/apple after its decrypted
See what differs from a dump of the same app from two different Apple IDs/iTunes installations/iDevices.
See if a consistent file hash for the IPA can be achieved by dummying out unique values


Item Status

cmd files should be un-excluded Done
the missing cmds should be added, plus the z64 file to go alongside the cdn content as an alt format. dir2dat of said files:

not sure which titles these go with though, who dumped the cmds and from where and who converted the cdn contents to z64. Jhynjhiruu knows about this.

Hiccup has asked Jhynjhiruu about this.
Should the cmd files from sources like these be removed from the sources ? If they are just taken from the scene release, then they should be. They should probably be set as "Trusted Modification" too. Hiccup has asked Jhynjhiruu about this.

Wii/DSi/3DS/Wii U Digital

Item Status
Make an easy too use tool for people who want to download contents from the Nintendo CDN in bulk, in a way that can be easily imported into datomatic and includes metadata.
Check that the "made-up" title version suffixes that cetks have been given match the title version field in the cetk itself.
Preserve the "met" file that each title has, on at least the Wii CDN, if not others.
Confirm which sources marked as dumped by Larsenv in the Wii Digital Deprecated and Wii Digital CDN dats were actually dumped by him - he's said that some/all weren't.

Item Status
There is some more info on undumped Famicombox carts here and here


Item Status
The lists of "ROMs that may be unique to the USA/PAL" release should be sorted based on the "ROM common" column in the master lists, since that column seems to say if the ROM is unique to that region.
Look at this


Item Status
A bunch of archives don't follow the special numbering scheme correctly:


Item Status
Import Connie's GOG dats
Import Gefflon's GOG dats
Find a way to make it easy for Gefflon to add new GOG stuff to DoM directly (e.g. make it so certain items can be marked as "current"/"latest", so a custom dat can be generated with only those items, like Gefflon's current dats)
Look into GOG API

Atari - 2600

Item Status
Incorporate data from (with credit), if there's anything new/useful there.

Nintendo - Misc

Item Status
For the large disk images, add hashes for deterministically compressed versions (e.g. rv7z) and exclude the non-compressed one. It'd make the files easier to handle (less disk space needed, no need for people to compress/decompress themselves).


Item Status
Check for (mainly proto) ROMs that are corrupted due to being dumped using old dumping hardware like gamesharks and old copiers:


Item Status
For bad dumps with comment1 reason set to "[grw0 partition not in factory state]" (and not any other reason in addition), change the status from the default bad status to "HasSave" bad status
