Hey there!
That’s sad - lots of good stuff on that channel.
I will soon be in the business of making Hisako videos again - just need to get some software/hardware issues worked out!
I do have some stuff on my YouTube channel already though, hopefully you can find something helpful there! https://www.youtube.com/channel/UCDowokhK_YQHvXkMZ4_RyHA
If you see anything going on in the match footage that you have questions about, hit me up!
Also - I linked a bunch of threads, some containing videos, in the stickied Hisako Tech thread that Finchomatic posted.
Happy to have another Hisako around these parts, cheers!
