It would be fun to have a lot of documentation here for IFDB download links. Here’s the gist of it:
IFDB just links to uploads elsewhere; you can’t “upload” to IFDB
You can upload to IF Archive. Once the link is processed, you can grab the link and put it on IFDB.
When you do, for Inform games, you’ll want to link directly to your Z5 or gblorb file, and check the box, “This is a playable game file or it contains a playable game”
Then, you’ll want to make sure you pick the right format (“Glulx” .ulx “Glulx/Blorb” .gblorb “Z-Code” .z5 “Z-Code/Blorb” .zblorb)
Today, this is so complicated that I think regular mortals kinda can’t figure it out. Part of what makes this so complicated for ZIPs is that we have to link to Parchment and embed an URL in the link to unbox. The embedded unbox URL itself has an embedded URL to IF Archive, plus an embedded relative path to the game file within the zip.
That being the case, I think I’ll leave the rest of your description out of the Handbook, or shorten it. My main goal, in that brief section, is to tell people how to make their game publicly available.
I’d add physical distribution. Mini box containing USB drive + paper instruction + feelies. The drive will contain various formats, including 8 bit versions.
Kind of like your very own Infocom mini gift boxes
