Wow. For the past few days being absent due to my illness, devs are heating up against unofficial builds.
Now, I agree with B3N30 about hacks making them mad and I also agree with other people who supported unofficial builds.
I'm between the two tbh. I use Official Canary build in my free time, playing Metroid: Samus Returns before going to my 3DS and play it for advancement. I also use the unofficial builds(not Valentine's builds) for testing purposes and high quality gameplay like Smash 3DS(same result on Samus Returns but I mostly use the unofficial build for Smash Bros).
The unofficial build I'm talking about is Senjosei's build(the one with xBRz).
One thing I don't like about Valentine's build is the ticks. The ticks pretty much forces me to change the value for a specific speed which I don't have time for that, typing from 10500, 10600, 10700, etc. The last time I use his builds was the Mario Maker fixed(it has hacks too but still works fine for me). Also, each time I change the ticks, game is pretty choppy. Game runs 100%, but it have like 25-30FPS instead of 60FPS.
In my opinion, I think Valentine's build is BEST for only low-specs PCs who wants to play Monster Hunter 100%. Don't get triggered on what I said. It's just my opinion and I agree both of you guys. I mean, most of the time I saw someone using Valentine's build are those who have weak PCs.
