On an unrelated note, I've just noticed that this run (https://www.speedrun.com/pwaa/run/yd93g2wz) is a PS4 run on the Original Release leaderboard which should be moved to the Trilogy Release leaderboard.

Back to the topic at hand, I've deleted my turbo runs from the leaderboard. Here's a list of all the turbo runs currently on the leaderboard yet to be removed:

To clarify, I am okay with using it if it's deemed legal, since I've already submitted two ILs with turbo. I'm not in favour of it being legal though, and the distinction there is important. This is a position I've come to after considering the problems associated with turbo use.

My main concern that prompted me to make this thread was to find out what the ruling was so that I wouldn't run the game with turbo for many more hours only for those runs to be removed later.

I think I share the sentiments above, there's a lot of inconsistency between platforms, and the use of turbo is generally considered to be cheating in most speedrun communities. I'd vote to ban.

Also, if you need any assistance spotting turbo runs, I'm happy to help in any way I can! Thanks for taking the time to reply.

Edit: SramX_'s Original Cases in 1:47:29 run is the only other turbo run aside from the ones mention in my original reply above.

Yeah, I'm happy to use turbo.

I'd run that for sure, LOL! Meme categories are great!

I haven't seen one around, but I'm very involved with speedrunning the trilogy and happy to converse with runners of the game! If you'd like to join, there are already a few Ace Attorney runners here, and we've got a nice fun community! https://discord.gg/8gKeCXr

I also know that all of Tsukumo's attempts use turbo too, as he was asking me about how to skip through text as quickly in my server! My 5:20 (obsolete) and 5:18 runs of The First Turnabout IL and my 20:28 run of Turnabout Sisters IL use turbo. All of WickedxMage's IL runs and his only full game run all use turbo.

I don't know of any other submissions using turbo, but I'll leave these here for easy reference and potential mod edits.

Edit: It looks like another turbo run was accepted onto the leaderboard so I'll go with "it's legal" for the time being.

Before I start to try beat all of my old scores, I wanted to ask about the legitimacy of using a turbo button to optimally skip through dialogue in runs.

All of WickedxMage's scores use turbo, and I in turn have submitted the first two level runs of the first game also using turbo to best a couple of his times, which have beaten some of my previous mash-only scores. However, I've noticed he's deliberately avoiding any mention of his actual method in his YouTube comments which leads me to think this is an attempt to be sneaky about it.

You have to either map a button to function as a turbo button or use another controller which has such a functionality. For proof, there are runs of his with audio where you can clearly hear the controller buttons being pressed during menu navigation, and staying completely silent during the dialogue. Also, you can cross-reference these runs with a run using turbo to see they skip through dialogue at the exact same speed, so long as you're holding skip and the turbo skip button together.

For reference, my two IL runs both state the use of turbo and how one can do the same thing on their own in the video descriptions, and I've answered questions in my Discord server about this.

I obviously don't mind whether or not this is legal on the leaderboard, but there are some legitimate concerns for the other platforms where it may not be as easy (or possible) to use turbo.

Something like a Turbo and No Turbo tag could be used to separate the two via filters, or turbo could be outright banned, or it could remain legal with no relative change. I figured I'd just check here to see what the consensus and ruling would be. Thanks for reading!

Aww, I actually just picked up the game today and I think I'd be really interested in running both of those removed categories! All Gold Feathers has a pretty straightforward goal, but I do see the issue with the 100% rule changes.

I found after watching a couple speedruns of this game that the section where you interact with King André for the first time is a bit buggy if you skip through the text using both the Esc and period keys. After a bit of messing about, I've figured out what triggers the optimal text boxes and how to prevent the drawn-out walk down the stairs, so here's a video that explains it!

I did my first few attempts on Japanese, but after you mentioned the speed difference I went back and checked the first cutscene, and English seems to be slightly faster! I think this might also be the case overall since I managed to improve my best attempt by a few more seconds.

A problem with this is that the game doesn't count Turnabout Goodbyes as complete and unlock Rise from the Ashes unless you sit through the entire credits sequence, despite the IL rules ending the run at the last objection. This would in a way be somewhat equivalent to exiting the game prematurely and loading a save file from later on. That said, this is a NG+ category and so Rise from the Ashes will be unlocked regardless.

I'd say it's questionable, but it definitely also depends on what others think of the matter.

I've just recently tried this method out and it's crazily fast! I found a bit more success with Single Box Skip than with Full Box Skip, managing to get a 5:50 on The First Turnabout.

I've only just recently run into this, but I think it's an important issue to resolve. I've been trying to start the timer on the first frame after difficulty select, and end after the last frame of the text box vanishing after reading Volume Fact. The advantage of this method is that it's relatively easy to time when counting frames, and most of the other runs on the leaderboard seem to be timed in a very similar way.

All of the releases have some gameplay differences, Eternal just happens to have the most prominent of the bunch. Rather than creating separate categories, I think it'd be most intuitive to either have Eternal runs be submitted to the difficulty categories that correspond to the difficulty selected in-game since all the other versions also follow that principle, or remove it entirely and create a new page for Eternal specifically. Creating new categories seems like a strange compromise because it's a game and not an in-game option or route.

I'd personally vote for the former. If a run on Eternal is done on what the game considers easy, it should be submitted under that difficulty. Those are just my thoughts though, what does everyone else think?

A year has passed and I've only just now found a possible improvement regarding the setup for the clip to the mines. While messing about with some timing comparisons during a stream, I stumbled across a different method for performing it, which has much tighter timing, but is faster by about half a second.

Here's a Twitch clip comparing this method with the old one:

Could I please have my username changed to "TheBarinade"? Thanks in advance!

I agree with you on the run where you select Time Attack to begin instead of beginning a new game.

As far as the run where you reach Darm normally is concerned, I think the arbitrary nature of the run could warrant a separate category, depending on what everyone else thinks. Something like "Darm%" maybe?

The run where you begin a new game, reach the first boss, activate the boss loop and abuse the glitch at Darm to put the game back in story mode sounds like it should fit within the regular Any% category, since you start the game at difficulty select and then technically beat it by any means necessary, unless I'm missing something. I don't think that whether or not the run is interesting enough should change that.

I personally really like the idea of adding a Time Attack category, I'd certainly be interested in running it. I'd vouch for the full-runs-only approach because it's simpler and the bosses can't be tackled individually, as you said.

It would be much quicker than other categories and there's a built-in timer, so I think it has potential to be very competitive!
