One could possibly try to crowdsource the resources. Let's say you ask people here (on the front page until the jam begins? -- well, it seems pretty important, and there is still some time left), on SNES dev Discord, and at NESDev (in a new topic?) to list like 1-3 of their favourite links.
Then these links could be put on GitHub (or on some existing wiki if people would prefer that instead). A fancy page might be created later on/after the jam, if someone will feel like it. For instance this list currently is just a "bare" GitHub page: https://github.com/balintkissdev/awesome-dos
I can begin...
