HI Everyone, This is an updated thread of the same topic found here. We weren't able to contact the OP so we just decided to make one that we can maintain/update! Reasons for the creation of this thread: The original thread provides a link to DDR Ace (DDR A) which is data dump 20190422. Technically, that is not DDR A20 although it contains some A20 data already pre-loaded. We are unable to contact the OP of the original/old thread in order to ask him/her to update the link to the data dump. A long way has gone in terms of methods/procedures for setting up the game, DDR A20. Of course we give due credit to the people behind the original thread because they exerted efforts doing trial-and-error to make things work! However at this point, the procedures are already well-established and newcomers are having difficulties in looking for the proper procedures/steps/fixes, since the original thread had bits and pieces of information all over the place (which again, is because at that point, people were still doing trial-and-error). At this point we can already reorganize the information in a way that can easily be found/read, hence, the creation of this thread. NEW!!! This thread is now updated to support both DDR A20 and DDR A20 PLUS! Thanks Admins! Topic for old release here.

Butterfly (our fork) has gone a long way. What initially started out as an individual project (a.k.a. "topet's butterfly"), eventually became a small group's project. On that note, this small group of individuals do not look at, nor weigh, their contributions in the quantitative sense. The fact of the matter is, there is mutual dependency in the contributions that went into (our fork of) butterfly in its current state, such that a missing piece/contribution by any single one in this group couldn't have made butterfly "whole" all by himself. In this sense, our contributions are weighted qualitatively and hence, as I personally see it, all are equal and therefore all individuals in this small group have equal stake for decisions involving this fork of butterfly. These are the people who have helped make butterfly what it is today: @tw3nz0r @bman @Towlesy27 @Sirk @One Eternal Ash @kanor And of course, @skogaby who is the original author of butterfly. I've only had a chance to talk to him a few times and learn a thing or two. But that simple act is what enabled and fueled me to embark on this journey. This decision to (hopefully, momentarily) stop openly supporting the use of butterfly with DDR Arcade (Ripped) Data is a very painful decision, at least for me personally, because - and again, this is in no way undermining the group that made it for what it is today - the fact remains that it started as an individual person's project. As such I would almost say that this is my "baby" project. And as "small" of a project as it may be in the eyes of the more technically inclined, I unfortunately was "technically handicapped" throughout this entire journey, so whatever "little achievement" you can see (from the eyes of a technical person) is actually a milestone and a source of pride for me. I am not about to be hypocritical about all of this because at the end of the day we know what "THIS" is. Do know that I personally took it with a heavy heart to make this decision. But I think, for the preservation of the greater good who will and should benefit in the long run, I believe that this decision has to be made. Out of my love for the work that has been done, and out of consideration for the many others who try their best to help with the sustainability of making this game available, I am going to release a "final goodbye" public build (hopefully, goodbye only for now). This build is enough to last you up to any 2020-dated package, and will cease to fully function when the 2021-dated packages are leaked to the public (or when you use our butterfly fork on any 2021-dated builds). In the meantime, you may use other 3rd-party online servers which provide the essentials for enjoying the game (score saving/tracking, score rivalry, force-unlocking of all songs, etc.). It is unfortunate that we had to (again, hopefully momentarily) stop making public builds since our fork of butterfly, although primarily envisioned for offline use, offers a very rich level of support and experience for DDR that goes the extra mile, in fact way beyond the essentials. Nonetheless, I have huge respect for all the maintainers/owners of the 3rd-party online servers. Putting up a server to function online where there a lot of users is in fact a stressful thing to do (on top of the fact this is purely voluntary plus volunteering material and non-material resources to maintain it). I am amazed at not only your work, but also your dedication for doing this. I am a patron of some of these 3rd-party servers too. I personally hope that things will eventually turn out for the better because I am still very excited in helping others as you have seen me do. Let us hope for the best and make this a learning lesson as we move forward.

This isn't really "fixed" as much as it is hacked and tampered with. I recommend updating the Asphyxia plugin with the new XML instead of hacking the game if thats how people are playing and just using the original startup.arc unmodified. I have run into stability issues with modified dll and arc files after 4+ hours of the game running. Maybe its fine if you start and stop the game when you go to play, but I personally leave my machine running all day and don't ever turn it off. Also there are songs in the data that are missing from this startup.arc EDIT: Update the plugin. This is all we need to do for asphyxia to load new songs: https://github.com/22vv0/asphyxia_plugins/commit/d1f46b47e82bfb15d0feb49f35a2a757c1dcba8e Just add them to this XML here with placeholder difficulties to unlock. I updated the 5 songs that were released with proper difficulties, the rest are placeholders just to unlock the song until we know what the real difficulties are. Here is the link to the updated branch: https://github.com/mcalfin/asphyxia_plugins/tree/mdx
