That's fine and dandy, but it'll save you many long hours of frustration to see how other people that have done this for a couple of years successfully decided to go about it. That mentality is what causes burnouts, hiatuses, and eventually giving up on shmups as an entirety. You can try to figure out, say, a Rubik's cube on your own, but chances are that if you don't use an online guide, you're going to just waste hours upon hours shuffling a plastic cube around and then becoming frustrated because your hours of work have come to nothing.
Be patient. Rome was not built in a day. But at the same time, you cannot make a good building without studying prior successful architecture. Trial and error only works so far. If you think you can get through Touhou without extreme frustration that takes the fun out of shmups by trial and error, you're going to prove yourself wrong very quickly.

Pardon the greentext, but I'm sort of incredulous right now. Nobody that matters is going to think less of you because you decided to use something that you had the ability to in order to obtain the skills/practice needed to win fairly. It is not unfair to watch replays or use software that allows you to practice places you need to practice. Would you rather that, in platforming games, checkpoints didn't exist? That's what practicing a stage without some level of practice mode feels like. You are going through the same fucking level over and over again and you're going to hate yourself and the experience as a whole for it. It feels like you are saying "I have the ability to use this checkpoint but it's kinda cheap so I'm just going to jump right the fuck over it." I am not trying to insult you. I am trying to keep you from burning yourself out. If you find something fun, that's fine, but don't frustrate yourself doing something that you have a method of making easier in a way that it will appeal to purists. You know how many Touhou purists there are? Not many in the English community.
There are ports of CAVE shmups that allow you to go into levels with specific scores, life/bomb setups, and you can start from bosses. You know why? Because CAVE is smart enough to realize "Hey, we don't have a reason to milk quarters out of you anymore now that you're not using a coin-operated machine, so we're going to allow you to get as good as you can get and as conveniently as possible."
It's not unfair to use cheats for practice. Never use them for actual runs, but for practice, anything that works for you will work.
Well...
I am sorry but I just, quite simply, don't share your opinion.
As stated previously, part of the reason of why I play Touhou (And other games know for their difficulty), is because I tend to love challenging games and trying to beat them. Its just a personal goal, okay? And because of this, I try to avoid almost all extra help, particularly replays and videos, because, once again, part of the experience to me is making up my own strategies to overcome said challenges. (Exception: If I have already done the goal myself I don't have a problem with watching videos. I have watched a lot of PCB 1cc Lunatic videos because I already 1cc?d it myself long ago so I got no problems with that!).
As for the SA Extra Bosh Rush. Once again, I still kinda need to practice the stage anyway, besides there is no boss rush for, say, IN extra, so I just feel it isn't right....Sorry but that's just how I feel about it. The stage is also fun to play. Really, most of my complain was directed at Koishi?s very first spell, and how I feel it was just a tad
Too much for a first Spell Card, that was it. Other than that, I like the challenge

I appreciate what you are trying to do, to keep me from getting tired of the games with my personal approach to them... but, with said approach is how I have 2 Lunatic 1cc, almost all Normal Clears, Most Extra Clears except 2, and I even did the all the Spell Cards on ISC without items, and I have been enjoining the games just about as much, if not MORE than the very first day I started to play them (which was around 1 year ago)!!!.... So I say its been working just fine so far

If anything, the "Burnout" you are speaking about so much is going to happen
SOONER if I use the extra help, such as replays and vids, since I would then be clearing everything faster, I would be annoyed due to the fact that I didn't really came with said strategy myself, and I would complete most of the stuff in the games faster, meaning I will eventually get most of the stuff I want done (I dunno, the obvious one is getting all Lunatic 1cc someday!) and THEN I would get the Burnout: With nothing left to do, I would just kind of stop to play Touhou then!...
Except for scoring, but I honestly couldn't care less about scoring

If anyone wants to use the SA Boss Rush thing to practice, then more power to them- I think its fine and no one should look down to people using that because it is just a stupid argument. But as for me, well, it is my decision. Also I NEVER claimed replays or the like were cheating...
Finally, I would like to clarify that I am not doing all of this to "Prove" something to someone else. It is because I just find it fun, which as you said, is what games are for right?!
