Note: this is a patched version of "[EG] Gunbuster OVA BD - Episodes 1-6 + Science Lessons & Specials", which can be found here: https://nyaa.si/view/644786

There were issues with missing/incorrect subtitles, but thankfully, a few years after the original post, a commentor by the name of Nick700 posted patches that fixed these issues. This torrent has those patches already applied.

Other than that, this release is the same. It includes both the original 2.0 audio track, along with the rerecorded 5.1 audio track that was made after the original audio master tapes were lost. According to the original post, these are the specs:

Video: H.264 10bit @ CRF17.5-18
Audio: FLAC
Subs: Aegisub based on REVO

Special thanks to EG for creating the original release, along with Nick700 for providing the patches.
