Over the years, I have found several videos posted up by a "Spikespen" with english subtitles. Unfortunately, he had the habit of hardcoding them to the video, and had quite a few misspellings.
During bits of downtime here and there over the past couple years, I decided to convert these subs into .srt files, and fix the misspellings, and some of the grammar. Now, I can't vouch for the accuracy of the actual translation, but I'd like to think I did a fairly good job of getting the timing right, at least on the copy of the files I was able to find. Also, he had a habit of cutting out large swaths of the original files, so there are areas of these files that are untranslated.
With that, here are the translations I was able to convert:
IENE-206
IENE-251
RCT-203
RCT-280
RCT-322
RCT-352
RCT-409
RCT-429
RCT-472
RCT-504
RCT-520
RCT-536
RCT-556
I checked the list that was posted in
this thread, and only RCT-429 is already on the list. Hopefully a few people find this helpful.
