The devs behind discmaster have been quietly working on discmaster 2 over the past several months.
It won't be ready for several more months. They are hoping it's ready before 2025.
Here are some of the new features and improvements:

New Items!

The biggest change is that new items can now be added to discmaster 2! It took a massive refactoring of the code behind the scenes, but when discmaster 2 launches, new stuff can be added to the new site on a continual basis. (The current discmaster 1 is basically 'stuck in time' as a static snapshot)

New Features

• 3D poly objects are now supported and can viewed (textured or wireframe), rotated and zoomed (demo video)
• Any CD/disk/file/folder can be opened in a Mac or PC emulator with 1 click
• Audio and video files are now transcribed and spoken words within them can now be found with search
• When viewing a text file, you can now change what type of encoding you want to view the file as
• ANSi art files can now be viewed as animations with different baud rates and fonts
• You can now search for items on the category pages
• Unsupported/unknown files now show a hex dump view of the file contents
• You can add ?hex=true at the end of any view URL to force it to show the hex instead of the normal viewer
• You can add ?output=json at the end of any 'view' URL to get the JSON version of the page

Improvements

• All files have been re-converted with the latest dexvert which supports hundreds of additional file formats and improved detection and conversion of previously supported formats
• Image filenames on browse/search pages are now visible even if you don't have CSS support. Additionally the filenames can be highlighted/selected and are findable via Ctrl-F. (Previouslly these names were generated via CSS which had a negative side effect of making them un-selectable and only visible on browsers with CSS support)
• Image filenames now show up on more image sizes. They also should be smaller on smaller images so they don't cover up as much of the image
• HTML files from items now render better in regards to differing charsets and links to other files
• Downloading an HTML file now downloads the original un-modified file (before there was no way to access the un-modified version, you always got the discmaster modified HTML)
• Changed speed dropdown to be a regular SELECT element for better browser compatability (before it was a hacky CSS/label monstrosity)
• Browsing pages and search results now have sections for each type of file (before many were combined into 'Other')
• File sizes are now shown to 1 decimal point such as 1.4MB (before you'd just see 1MB)
• Various ANSI-art formats now show title, author and group meta information when available

Search Improvements

• Extensions can now be searched separately from the main query. This allows you to restrict content querys to only include files with a given extension or exclude specific extensions. The filename still has the extension in it, so just searching 'png' in the main 'search for' query will still return *.png files.
• Can search for folder names
• You can now use ? in the search to match any character, such as t?st matches test
• You can now use astericks * at the *start or end* of a word to find words ending or starting with a word
• Words can now be grouped with (parenthesies AND (use | combinators))
• Results now properly honor multiple - uses instead of just the first one
• When choosing to 'Omit Dups', the number of duplicates per file is shown. You can also sort by the # of dups.
• Results now show original case of filenames
• Results now correctly sort by relevance when chosen (before it was always filename when relevance was chosen)
• Improved support for non-english searches, especially Japanese
• Newly added items are immediately available to search (used to be a 1-2 day delay)
• Can find the full contents of indexed HTML pages (Before it only indexed the text content of the page, which meant you couldn't find script content or old HTML tags, etc.)
• Can search for files based on the file hash (blake3) by adding &b3sum= to the search query in the address bar
• The JSON output of search now returns a TON more information about each result (including file hash (blake3/b3sum))
• Can order results by format and family
• The search URL now uses human readable words for Genre and Category searches instead of id numbers
• When including the item name in search results, the item category is now also shown

Other Changes

• All pages are now dynamically generated on request instead of being pre-generated and static. This allows future bug fixes and improvements to be added instantly for all items, rather than needing to re-generate a billion static files.
• Search counter added to index page
