I'm curious, but if it's harder than door skip I probably won't do it

I'm having trouble with the bosses at the end of the Shovel Knight any% run (Black Knight, boss rush, the final bosses). I got the magic armour, so I take more damage, which is probably the reason because I could do them a lot easier when I played casually. Is there something that would make the bosses easier for me (like more health or defence or other things like that) or do I just need to get good?

So I just started learning any% shovel knight. I got to the Flying Machine level, and was just by the item that you need to buy, but I only had 2,000 gold when I needed 4,000. It might have been because I died a lot, which hopefully won't happen later because I was kind of messing around. It's not a big deal now because I wasn't in a run, but was if this happens when I am in a run? Is there a backup or do just I need to reset?

I just started speedrunning super mario 64. The thing is, I can't submit any runs because the emulator I'm using is banned for some reason. The only emulator that is now allowed is project 64, which is only for Windows. I have a mac, so there's no real good way for me to do that. Is there another emulator that could be allowed for people with mac? That would be super great :)
