Listening to the documentary now.
For ROM hacking and translation projects, I recommend checking out Romhacking.net. Use the Translations and ROM Hacking links in the upper left, and filter/sort the list to your liking.
As for interesting stuff, I'd say it depends on who you're asking. I'm mainly a fan of 16 to 32-bit era translations and re-translations (translating [typically Japanese] games into English that already have an official English release.
New stuff in the translation & hacking scene that I found interesting:
- English translation of Sutte Hakkun (SNES)
- Bug fixes for Space Station Silicon Valley (N64). I actually booted up my N64 with a GameShark to try this out and was very happy with the ability to finally 100% the game!
- Final Fantasy 6 (SNES) keeps getting various minor bug fixes.
- The previously unreleased Star Fox 2 (SNES) was dumped from the SNES Classic and the fan translation was added to it. There are videos of people putting this game onto a SNES cart with a SuperFX2 chip and playing the game on real the SNES.
- English translation of Wrecking Crew '98 (SNES)
There's also a the Reunion Project (3 years going, IIRC), which attempts to update Final Fantasy 7's PC and PSX versions with bug fixes and better dialog.
