This topic is for the purpose of discussing #7754: TheRandomMaster's 3DS New Super Mario Bros. 2 in 26:50.41

Ooooooooo another 3DS. Kinda want to claim this one... since scripts do be the first thing I developed for Citra and was trialed by someone else, so I want a full crack at it as well.

The TAS instantly desyncs for me on the latest nightly build (1800)...and I'm also gonna mention I'm personally not a fan of a canary build being used. Dunno if something's off on my end. EDIT: ...okay, something's really screwy in the latest nightly. I can input touchscreen inputs...during playback.

It should be the most stable on Citra Canary builds, I highly doubt it will work on any of the Nightly builds. EDIT: I didnt know Nightly Builds supported TASing in the newer updates. Never used Nightly because only Canary had TAS tools at that time.

I can verify the movie syncs on the nightly build 1800. It's important to note that you need to delete the save data before running the movie, Citra seems to not have any flags that tell the emulator not to use sram, so it'll initially desync because of that.

I haven't watched any speedy NSMB 2 runs since 2016 due to IRL stuff so I was happy to see 3DS games TASable back in 2020 even if Citra is rough around the edges to use. I was going to ask if under 500 coins is doable to skip the 500 coins collected milestone message but that might not be possible? One downside if it is possible is that it can lead to restrictions/less entertaining play on auto-scrolling segments such as the underwater stage in Mushroom-2 where Gold Fire Flower kills would be kept to a minimum. A run with SRAM can only save 3-6 seconds* over a fresh file in traditional gameplay (so excluding first time booting up messages where you hit OK on a few questions) but producing a genuine file that isn't save edited will take a long time. * Clearing stages that lead to a save message including Towers, Castles and Warp cannons requires the overall coin counter to be updated before the message pops-up. With 9,999,999, the coin update part is skipped. Other stages doesn't have this rule as Mario is able to regain control as the overall coin counter is updating. I voted yes on this. For people who haven't watched the run before. Final boss Bowser is measured in number of slashes. Floor 1 - 2 the minimum number of slashes is 4 Floor 2 - 3 the minimum number of slashes is 5 Floor 3 - 4 the minimum number of slashes is 3 Assets such as pipes to enter. platforms to land or big switch to activate only appear/operate when they are close to the in-game's camera shot. It's not like Super Mario 3D Land where you can perform some crazy off-screen strats to skip actual auto-scrolling.

For me, besides of nightly 1800, the movie also syncs on canary 2306.

So...as several people reported sync on the latest nightly (1800 as of today), I decided to fiddle around on my end. I tried various stuff, from changing graphics settings, audio settings, changing inputs to default (they already were default), even re-downloading the movie file....and nothing. It's as if the movie file doesn't play back on my end. Meanwhile, the OoT3D publication plays back just fine for me (it even syncs on the latest nightly). So I have no idea.

i also can't get it to work. No matter what i do. i'm starting to get a little P'd the F O

Also having sync issues. I went ahead and created my own test movie file, and that file has no issues playing for me. So I started doing some digging into the movie file to see if I could diagnose the issue. The file on the left is TheRandomMaster's movie file. The one on the right is my test file. The blue and the red color coding is used to separate data into the frames they are relevant to. The area I have highlighted is frame 46 of both of our movie files. The short and simple of it is that each red chunk and each blue chunk should be identical in size and position between the two files. However, frame 46 in my movie file is 7 bytes longer than frame 46 in TheRandomMaster's. The reason for this is because my movie started recording data for accelerometer inputs slightly before TheRandomMaster's movie. I have no idea why this is happening. By inserting 02 00 00 00 FE 00 00 at 0x0AD8 (the accelerometer data Citra is polling for at this time in the movie file), I fix the desync and the TAS plays just fine. I have confirmed sync with this fix. I have uploaded the fixed movie to my user files: User movie #638023496031275421

If it helps anyone, I got the movie to sync on a decrypted version of the game, not one that was encrypted then decrypted by myself. the hashes for the rom I used are as follows: MD5: FE21CBBD6229A31CDE2FA35452E94175 SHA1: 30DFCC26E94EB8BA787B560F0019589FC9254615

Synced on Nightly 1800 from Public Computer with benstephens1000's movie TAS fix was the last resort.

I can confirm sync on the latest nightly (still 1800 as of this writing) with the movie file provided by benstephens1000.

"Rerecords count: 3448" I usually argue why people don't try more input variations, but here I'd like to know how you didn't go nuts saving and loading states with your mouse for so many times? xD Because there's no hotkey for savings/loadings

Rerecord count is not an accurate way to tell how much someone tested inputs in a movie.
