General improvements

Add pictures, and a video guide, to each page
Add instructions on how to dump save files
Document common ROM chip serials. E.g. 6th, 7th and 8th character of the “MX” line on MX (Macronix) ROM chips seems to be the ROM size.
Nintendo cart pages: add info on “front of cart”/box serials (and non-standard carts if relevant)
Split dumping hardware table into individual tables for each console, and put them on the respective dumping guide pages
General Disc Dumping guide: add more information on advantages of certain disc drives (e.g. Plextors)
GB/C: update the tool overview table and then move back to actual page
GBA: update the tool overview table and then move back to actual page
Document using 7-Zip for hashing
DS: Add info on box serials (and non-standard carts if relevant)
Add notes about what to do with your ROM image and dump metadata if you don't want to submit it to a cataloguing organisation
Add relevant DS images from that exist under carts:nintendo:ds to the page
Add note about checking No-Intro/Redump to see what is highest priority for verifications etc

Create Atari Cartridge dumping guide.
Atari 2600 - dumpable with custom OSCR adapter or Custom adapter for Retrode 2
Atari Lynx - Joeylynx or lynx pi hat
Atari Jaguar carts - either desolder ROMs and use ROM programmer, or use a BJL-modded jaguar and the bjl_dump homebrew
Create GBA e-Reader guide
Create guide for Bandai Wonderswan. OSCR adapter requires harvesting cartridge slot from a real Wonderswan. There's also a Tengu cart reader. A flash cart in the early 2000s named WonderMagic could also dump carts, but it's now extremely difficult to find. Carts are secured with two T6 Torx screws. Make sure to not include save data in dumps.

General: more “TapeDump”-like homebrew for different systems could be useful. Especially if paired with cheap hardware to allow easy and safe cart swapping.
General: Look into clone consoles that have external storage + cart slot, if they exist
General: Look into if using tasbot/ACE could be more affordable than flashcarts, for running homebrew
GB/C: Dumper for GameCube via Game Boy Player or Game Boy Link Cable. There are GBA methods, but do they work for GB/GBC?

Is it worth dumping each chip individually for some carts? Examples of carts where this would be useful: different parts of ROM exposed depending on PCB configuration, some kind of circuitry for byte-swapping the ROM output (2)? Maybe just looking at the PCB is enough to find special cases like these.
Add explanations of why the different pieces of info are useful to record to Gathering and Submitting Dump Info (Detailed).
Hiccup's notes: https://hiccup.miraheze.org/wiki/Notes_to_assist_with_dumping_guides
It may be a good idea to overdump (dump past the maximum known capacity) from some carts on some systems, to make sure all the ROM is dumped (even if the capacity is written on the ROM chip), and then analyse the overdump to find the actual size. Maybe this is something that could be done by the dumping hardware itself - maybe make suggestion on OSCR github discussions.
Hardware: integrate Lesserkuma's cart_reader_dumping_compatibility_chart.xlsx
Some carts may have DLC in the save data. Add a note to the dumping guide pages about this.
Rewritable Hard Disks and Flash Media: add instructions on how to censor personal information without altering the surrounding data structure (e.g. FF/00-out file contents without modifying the filesystem metadata or shifting data)
