low% uses fireball instead of dash because dash is 2% and fireball is 1%, and we can't get mantis claw without either fireball or dash (or gruz mom but that's more complicated) so the best option is still to get fireball and skip dash like it always has been
For switch runs the best option would be using a capture card to record your screen, but if you can't do that you would have to use your phone or another camera to record your tv or monitor and make sure it has decent video quality. Console runs use Real Time (RTA) for timing so you don't need to use livesplit, but if you do want to use livesplit you'll have to manually start, split (if you add splits) and end the timer. If you wanna learn more about HK speedrunning I recommend you join the discord server linked on this game page.
I'd recommend joining the hksr discord server as most resources and guides can be found there
The only board with no runs is not possible to be done with our current ruleset. We also can't remove the board without having to change the SRC layout for Great Hopper% so I guess it's just gonna stay there lol
1221 can run poorly on some devices (or not even run at all) and since the majority of the colo1 leaderboard is in the latest patches I think it should become its own category and move all latest patch runs to it. I honestly don't think it will be a competitive board but at least it's more fair for those who don't want to/cannot play 1221
autosplitting is not possible on console, to record runs you can use a capture card or in last case record your screen with a camera
there is a category in https://docs.google.com/spreadsheets/d/e/2PACX-1vSHyJ2ZdtTPvoudRJ_VAW_an61MumAHdsQOm4Z9wvn_ou73rxX9w9ydb_lDuyOTCnXvmb68HlMrjPYa/pubhtml# that is to beat all 3 forms of every boss in the hall of gods so if you're interested in that you can go for it, then go to the discord and post your time there and people will add your time into the sheet
you're timing it right, don't use the in-game save file timer because that one doesn't count main menu time and paused time
