I haven't checked in here for a while, so I'll answer a few questions now.
The link is permanent. It's a copy of the original folder, but it won't receive any updates - it's just a backup. It includes everything up to mid February 2025.
There won't be any further updates unless someone is willing to spend $20 (on subscribestar) and post the new link here. Also, the original link tends to get deleted pretty often, so even if someone were to step up for us, they’d need to keep updating it frequently. I did it once, and so did
Macaw0958 - it's honestly pretty expensive.
On Fanbox, it's "only" 2,000 JPY, which is about 14 USD.
I'll keep the folder and the link up for as long as it doesn't get taken down by the cloud service. Right now, I’m not using MEGA for anything else, but I have to admit - it's taking up a lot of space (around 80% of my cloud storage).
