Old school DDR Simfiles with the OG rating level?

I went to download some of the older DDR arcade mixes the other day and noticed that some (like DDR 2nd Mix Arcade) has (most) the charts rated with the new 20 scale difficulty rating instead of the original (legacy) 10 difficulty rating. It seems like any song that was later released on a "modern" DDR version with the new rating scale, has the new scale rating. But these charts are intermixed into older mixes that used the old legacy scale. So you can have half the songs in a pack using the legacy rating system and half using the modern one. This is confusing and makes batch/mass corrections difficult.

A good example of the mismatch is in DDR 3rd mix, where about 1/4 the charts have the new rating, but most are legacy.

Is there an easy way to get the arcade simfile packs with all of the same difficulty scale?

Yeah it’s a mess. You would have to rerate the older songs if you want that, I don’t think anyone has released a pack doing that. Itgpacks.com has DDR for ITG packs that are all rerated to the ITG scale, very similar to the legacy DDR scale but not quite the same. The old DDRUK simfile page that has the original packs from way back when seems to be gone now, which is sad.

Sadly, the links here (for those packs specifically) also seem to be broken.

here's a link to DDR for ITG

I prefer to load custom level ratings from lua tables rather than having to modify the sm files. It's up to the themers how to implement that. There is a tool to convert old to new ratings by teleshoes and make those lua tables to load for StepMania themes.

How does that work? Wouldn’t it change the rating for every song, including ones already on the modern/X scale? Like what stops it from grabbing a 9 on the X scale and making it a 12 or whatever like it would for a 9 on the old scale?

You only put sm/ssc files with old ratings you want to convert to X-ratings, then you run a batch script that uses a python script to do it. Apparently, it's only for linux (you can run linux emulator in Android, or bluestack for Windows with it). You copy the tables inside a song group table array and use them via lua function for MeterRating. MeterRatings function returns the original meter ratings if the steps doesn't have custom ratings for that steps.

This is an example I used in UserLand app (Linux emulator for Android). The result can be different from the actual but at least it's still useful in case you're curious how they rate.

OP, did you ever find the DDR:uk bumper packs? Cuz I know they're somewhere online, and if not, the wayback machine is a good option too. I'd offer them to you (cuz I have them) but I don't have storage space to host them anywhere.

Actually, I do have the old DDR UK packs on my hard drive. The reason for my original post was because I now have Groovestats enabled on my cab and noticed a LOT of charts just aren't being played by anyone but me. This is because the new GS tracker will track any song (which is cool), but in order for it to be "fair", it won't count the same song if the stepchart deviates too much from another. Example; My chart of "SONG X" from DDRUK might have a BPM of 150.01, but the ZIV stepchart of the same song has a BPM of 150.00, then GS will count and track these two songs as separate rankings.

This bums me out, because most of the community is getting their "official" packs from ZIV these days, so I figured I would update my song packs to the latest versions found here, but was taken aback when I found out a lot of them have mixed difficulty ratings (as mentioned in my OP).

I was hoping that by now there would've been a standard implemented into SM files where you could specify legacy and modern rating systems simultaneously and let the Theme choose which one to display, based on the users' preferences. But, I'm getting ahead of myself.

TL;DR = I got the DDR UK packs and they work fine, but almost nobody else uses these, so it's not great if you want to chase scores with other people using GrooveStats.

Yeah like I said previously you want the DDR for ITG packs from ITG packs.com. They’re the simfiles from here re-rated to ITG scale so some songs that were officially 8s old scale rate to 9 based on new scale ratings and other discrepancies from the old official ratings but that’s what most ITG players are using now. Someone else posted a direct link to them in the thread so they shouldn’t be hard to find.

So, the only other option you have is... changing the difficulty yourself. Again, I have done all that already with everything pre-supernova. I'm just a little hesitant to share my files because my SMs have their offset adjusted. You'd still have to go through each file one by one to edit their offset anyway. My entire stepmania folder is almost 60 gigs, and I have no idea where to host something like that anyway. Obviously zipping each mix and uploading them somewhere I mean.
