this is an accurate simulation of ddr extreme arcade, based on stepmania, which is unpack and run (everything included. songs, bg videos, etc). it is a 650 MB download. This is also worth considering for anyone who wants/needs an instant, good looking, dance game/simulation, with minimal hassle.

=================================
cumulative update. this fixes problems found in r2. apply this after unpacking the big zip.

http://ddr.bircd.org/beware_stepmani...e_20120208.zip

unpack this over the beware extreme tree, overwriting files. then run the update batch file or script. then "reload songs/courses" in stepmania.

fixes and changes in the update:

- i forgot to include the 2 patches for the lightsmanager code
- the BPM for "celebrate" should be 134, not 133.
- SKY high: complaint about bad sync at the begin (it's a bad cut in the original ddr song), fixed
- GET UP'N MOVE: the wrong song was included (from the solo version)
- Aoi Shoudou stepchart (from ddruk) had a wrong arrow
- "love shine" banner erroneously had odd height so it could look blurry.
- ending of HVAM should be after the music ends, not the last note.
- in the unlock screen, where it should say "12" it said "13"
- when you start a game it should say "Let's Dee Dee Are!", nothing else.
- rhythm and police: more accurate bg script
- redone "select style", with realistic "hilighted" icon, "buttons" can show on either side, and works in standard SM
- added setting to disable background videos
- max combo digits flash faster if AAA
- debounce patch
- don't repeat the same combo announcement in a song
- two background videos were missing: circle1R (xenon), heart3A (mahou no tobira)
- made edit/sync mode work
- BG script accuracy and fixes in: csfilsm, trip machine survivor, stoic, 1998, burning the floor, higher, kakumei, keep on movin, my summer love, memories, burning heat

============================================
troubleshooting, F.A.Q.

general troubleshooting, check and understand all of these before asking for help:

- be sure the main zip is not corrupted by verifying the size and a checksum with the ones given in this post. if this fails, download it again from another mirror.

- the archives are standard ZIP archives and can be unpacked with many archivers, such as winzip, unzip, pkzip, winrar, 7zip, etc. be sure to unpack with preservation of paths.

- you must apply the latest update. running a setup otherwise is not supported.

- do not combine this with a stepmania installation. unpack everything into a new, empty, directory.

- if background videos cause gameplay to be choppy, try to disable vsync.

- any functionality that is not in extreme arcade is out of the scope of the project and no effort will be put into supporting it. examples include rolls, note noteskin, edit mode, and extreme cs songs.

credits:
- Konami, for DDR.
- The Stepmania developers, for Stepmania.
- DDRUK for their song packs.
- SSGotenksUFO, T_Bone_X_Zeo, Amy, for lossless song rips
- ollec2004, Saotome2U, MagmarioX, Amy, and others for background videos.
- katze for his extreme announcer.
- AJ187 for extreme arcade ripped graphics

I have changed about every single aspect of the Stepmania setup:

- Stepmania code: lots of changes to the source code.
- Theme: made from scratch, using ripped graphics and metrics based on own observation.
- Noteskin: created beware extreme noteskin.
- Background videos: collected videos from various sources, encoded missing ones, and renamed (created beware BG videos 2005 pack).
- Background scripts: collected or made a script for all 240 songs.
- Songs/stepfiles: fixed some small errors in ddruk's stepfiles. Replaced all mp3's with oggs encoded (with aoTuV b5) from mostly lossless sources.
- Pad/cabinet lights:like DDR Extreme arcade.

Highlights/features:

Miscellanious:
- The exact same (240) songs as the DDR Extreme Arcade.
- The size has been reduced by removing unnessesary things. It now fits neatly on a standard 80-minute CD-R.
- Credits indicators: original SM behavior in "home" mode. In free play and pay mode, they show all the time, as in ddr. "Event mode" text shows in the middle.
- Arcade style event mode option added. Among other things, automatically toggles some SM settings to the right setting for event mode on or off.
- Freeze jumps now count as one OK, not 2.
- Scoring is exactly like DDR Extreme arcade.
- Judge window times: I saw in a video that the boo window appears to be ~0.16 secs (the delay before a miss appears). The actual timing is between "theory 1" and "theory 2". The "PERFECT" window is 33ms.
- Extra stage and one more extra stage are like DDR Extreme - same song, same mods.
- All music wheel entries for songs, groups, ABC sort, and random/roulette show the ripped graphics images.

Beginner helper/characters:
- By default, the beginner helpers show, but dancing characters don't. It's also possible to disable or enable both.

Ranking songs/courses, highscores:
- The correct courses and ranking are shown in the highscore screen (pop4, naoki neo standard, dancemania oni).
- Highscore screens have exact layout.

Select style:
- Separate pad and character animations.
- Player 1 shows konsento (robot), player 2 shows zukin (girl).

Select difficulty:
- In "Double" mode, beginner difficulty cannot be chosen.

select music:
- BPM has scrolling animation.
- The same sort modes and lists as the arcade (default list of songs, groups, ABC sort, etc), graphics look accurately like ddr.
- The same "codes" for mods as in DDR Extreme.
- Feet/difficulty look correct.

Select options:
- Shows the option icons.
- Shows the difficulty icons.
- Exactly the same options and same layout/fonts as the arcade.
- The highlight bars look correct (green for p1, brown for p2).
- Graphical option icons.

Gameplay screen:
- Note colors should be exactly the same as the arcade (based on ex cs jp emulator screenshots).
- White "explosions" for "Marvelous" accurate steps, even if "Marvelous" is not used.
- The timing of the white things on the arrows, and the receptor arrows, is correct.

Gameplay oni screen:
- Red flashing life/score areas if you lose lives.
- Dance points indicator animates when stepping on arrows.

Evaluation screen:
- Correct fonts and layout for everything.
- Max combo flashes if full combo. Oni "stages" flashes if all cleared.
- The percentage bar in oni mode works.
- Exact grades settle animation.
