Official Simfile Error Thread

I re-downloaded the simfile and checked the sync via ArrowVortex (with wave form filter on), and I don't see any problem. I also tried to play it using keyboard (used custom DDR-like timing) and I don't get any Good judgment in the parts you mentioned.

here is the video:

That's odd. Must be on my end then. May be because I'm using an older version of Stepmania, yet I don't see how that could be the problem. I'll try to see if I can do something on my end to remedy this if it persists.

On the topic of syncing, PRANA＋REVOLUTIONARY ADDICT (U1 DJ Mix) from DDR 2014 feels late after the first stop, which is actually the result of the song having bad looping (albeit not as bad as in The legend of MAX).

This is my attempted resync of it:

At least one official chart appears to have BPM changes under #BPMS that change the BPM to the same value. For example, in the .sm file for DDR 2013 - Windy Fairy:

#BPMS:0=180,4=180;

I noticed this while working on a script to count BPM changes by counting every comma character on that property. I also opened the file in ArrowVortex, and the BPM change was not displayed there. I think other charts under 2013 are also affected since each listed at least 1 BPM change in the script output.

Instances like these should probably be changed to avoid miscounts with simple scripts that don't check if adjacent BPMs are different.

Spanish Snowy Dance and Somehow You Found Me have that same issue too. Also, MAX LOVE from DDR X2 is missing a #DISPLAYBPM:180; tag in its .sm file, causing SM to display its BPM as 180~180. The latter issue isn't present on the Chinese version of the song however.

I ran a script to find some cases where BPM was erroneously changed to the same value, and these are the results:

The script works by counting the number of BPM changes and finding the difference between the min and max BPMS. If there is exactly 1 BPM change and no difference, then it's guaranteed that BPM change is to the same value. The script doesn't do comparisons mid-BPMS-string, so it likely missed many other cases where BPM was changed to the same value.

The "BPM False Change Counter" script is available here for use locally: https://drive.google.com/drive/folders/1kMe0AHRVjphqz8SFG0ZaI2mMv2dvuA57?usp=sharing

For D2R ("FREEZE" Special), that could be fixed by making the BPM at measure 0 163. The original D2R in the DDRMAX2 category does this too.

Additionally, a lot of the simfiles you mentioned could use updating (e.g. resyncs).

All ssq to sm tools have been like that when converting them and during that time I never bothered to modify or "clean" them until the release of DDR A. When I'm free, I will update them to match current standard. I'm sure it will take a lot of work.

Edit: I've been doing resyncs on my own eversince DDR A was released. I preferred not to update them (or some simfiles) because as far as I remember we had private discussion about it and most of the higher admins prefer the original data timing.

I updated the script to find all same-BPM changes in the #BPMS field instead of the previous limited approach. It now finds several more cases across various folders.

The updated "BPM False Change Counter.py" script is here, as well as a "bpm_false_changes.json" file with all affected official charts to update as of 2023 March 22: https://drive.google.com/drive/folders/1kMe0AHRVjphqz8SFG0ZaI2mMv2dvuA57?usp=share_link

Append edit: I created another Python script (Misformatted Attribute Finder.py) to collect a list of misformatted attribute tags that use incorrect casing (not all-caps). The only affected official file is "U Can't Touch This" from DanceDanceRevolution X (AC) (Japan), which contains the following lines:

#DisplayBPM:134;
#BPMs:0=133.829,4=133.391,157=133.446;
#Stops:157=1.353;

I don't think this affects how the .sm file is loaded in Stepmania, but Python and some other languages require .lower(), .casefold(), or equivalent for case-insensitive attribute matching, and consistent all-caps prevents potential errors when retrieving or comparing this info.

the true simfile errors were the friends we made along the way

---

This is a minor thing, but in DDR 3rdMIX LET THEM MOVE, the artist is listed as "N.M.R." instead of "N.M.R".

EDIT: Found another similar one. "BOOM BOOM DOLLAR (K.O.G G3 MIX)" has an extra period after the G, but in both it's banner and in Extreme2, it's spelled as above.

Also, is it just me or does the A20 category not have a pack anymore? I was updating some official simfiles to reflect the new charts they got and A20 doesn't have the button to download the pack, but every other pack I had to check does

Edit: it's back up, thanks!

Yeah, StepMania loads lowercase/mixed case tags just fine (and will properly save with uppercase tags if saved in SM). Other programs like ArrowVortex just choke.

I'm just mildly amused since I pointed this out like two years ago and I'm gonna assume nothing was done then. 😂

---

The CDTitle for I'M ALIVE from Solo 2000 is currently for Dancemania BASS#1, but should be Dancemania DELUX. Probably got mixed up with the Solo BASSMIX version.

The 5thMix song "Remember You" has a weird situation... In most games (Extreme to SuperNOVA2), it's Beginner and Basic charts were identical (and the Basic chart goes back to 5thMix). In the location test, they added a new Basic chart, keeping the 5thMix chart as Beginner.

On the simfile page here, the comment has data for the Location Test Basic chart, but in the simfile itself, it's still using the doubled up Basic chart.

I don't know if this was an intentional choice, but is it the correct one? Would it be more meaningful to include the Location Test version?

I think it's best if we keep Remember You as is because the chart you're referring to never made it into the final official release of any game.

---

There are plenty of charts in the simfiles that were never in an official game. A bunch of Beginner charts that were only found in the data of CS games, not playable. The Location Test chart was playable, at location tests.

An error that does not matter much: MATSURI (J-SUMMER MIX) in the Festival folder, has the same Beginner chart as the one in the Ultramix folder. In Festival, it has an unused Beginner chart, which is the same chart that would be later used in the Arcade version. So for consistency with the other Festival files (which all use the Unused charts, regardless of if they went to Arcade or not) it should use the Arcade/Unused chart.

A more bewildering difference, which I only have a small guess for: all 3 of them (Festival, Ultramix, Arcade), have different Basic charts, when RemyWiki claims they are all the same. By comparing them, Festival is just missing a few notes but is otherwise the same (worth verifying if this a transcription error or true to the game), while the Arcade chart has moved a few of the later notes one step later; is this an Arcade correction to make it line up better, or a transcription error in Ultramix?

(Sorry, going through them as I type this up, but) the Difficult charts are also different. Festival is missing notes, Arcade corrects quantization it seems? So it's likely Arcade and Ultramix are accurate, but worth determining whether Festival is.

(And just for the record, Expert charts are all supposed to be different. I didn't look at Doubles.)

Additional error, found 9/1/23: X3 VS 2ndMIX "REBORN MAGIC" Expert is listed as 10, it should be 9. (Verified on a video of X3 VS 2ndMIX as well as GRAND PRIX).

Rensen ryouran Beginner is listed as 3, should be 2. Was only able to find a video of X3 VS 2ndMIX to confirm it, but seems unlikely it would change to a 3.

TWINKLE HEART Difficult is listed as 7; it is 8 on both X3 VS 2ndMIX and GRAND PRIX.

Just in case it hasn't been mentioned, in the A20 pack BUTTERFLY (20th Anniversary Mix) contains the data for CARTOON HEROES (20th Anniversary Mix) instead.

Votum stellarum -forest #25 DDR RMX-'s preview start time of 17.15 has been incorrect for a long time. It should be at 15.71 according to this video.

There was a possible update to a stepfile, but I need confirmation:

On Bemaniwiki, the BSP chart of 十二星座の聖域 (Juuniseiza no seiiki) in the DDR A folder has an official A3 GROOVE RADAR Freeze value of 41. However, in-game footage of the chart in Grand Prix and the chart on Ziv have a Freeze value of 3. Bemaniwiki page link: https://bemaniwiki.com/?DanceDanceRevolution+A3/%B5%EC%B6%CA%A5%B0%A5%EB%A1%BC%A5%F4%A5%EC%A1%BC%A5%C0%A1%BC%C3%CD%A5%EA%A5%B9%A5%C8%28SP%29

The Freeze value visible at the beginning when selected in Grand Prix: https://www.youtube.com/watch?v=hbmC9fvEQic
Confirmation that the file is identical in DDR A: https://www.youtube.com/watch?v=9hjCokxkiw0
(unsure if these are official or simulated)

Was the chart changed to include more Freeze arrows, or is this just a transcription error on Bemaniwiki?

Edit:
Prey DSP has a similar issue. The Chaos value is listed as 9 on Bemaniwiki, but this differs from other sources.
Official gameplay footage from A shows 59 Chaos: https://www.youtube.com/watch?v=YyfvAQJRMxg
The Groove Radar generator estimate tool on the transcribed Ziv file shows 61 Chaos: https://zenius-i-vanisher.com/v5.2/thread?threadid=11050
Was the chart updated in A3, or is this a transcription error on Bemaniwiki?
