maimai DX:1st/Changes

maimai DX

Misc. changes

EASY charts and UTAGE charts are removed.
- Lowest difficulty is now BASIC; new BASIC charts can be as easy as level 1 (LOSER).
- UTAGE-only songs are also removed.
Freedom Mode added (Japan only). Basically Premium Free in IIDX. Insert 2 credits to play for 10 minutes. (Can be extended to 12 minutes by using a Freedom Pass)
The new maimaiDX-NET doesn't have the usage rights (利用権) designation that was in maimai-NET. Instead, most features are available for free with no time restrictions. Some features can be enabled with a "Geki! Chuumai-NET Standard Course" subscription for 300 Yen + tax (330 yen as of 2020), only available in Japan.
ちほー (地方, maimai DX:Area) added. It's similar to Maps in CHUNITHM, and serves as the main unlock system, including for limited-time events. つあーメンバー (Tour Member) is added as part of the system.

Rating

Rating is changed again, and is now called DX Rating. The calculation is similar to jubility in jubeat festo.
New songs + Old songs + Grade (段位) bonus
Rating for charts is now determined by highest score only. The "recent" slot (as it was called colloquially) in the old Rating system, that measures a certain number of recent playthroughs, is gone. This means that the Rating does not decrease unless your Grade drops.
The exact Rating values for each chart is now viewable with the Standard Course subscription. This makes it possible to deduce the formula used to calculate the Rating.

Hardware

The old camera with recording abilities is removed, because it was specifically made for maimai with hardware encoding capabilities, and couldn't be newly manufactured.
A new camera, labelled 思い出カメラ in Japanese and 玩家摄像头 in Chinese, is added in the middle of the cab. It can be used to take souvenir photos before or after a playthrough, and cannot be used to record videos.
An earphone jack is added under the circle for each player.
At where the old camera was, there's now a piece of plastic for players to attach their smartphone clips to record videos by themselves.
Japanese cabs have a DX Pass reader under the Aime reader. DX Passes can be printed from the Card Maker.

Regional separation

maimai DX is released in China under the name 舞萌DX, 7 years after 舞萌, which was the first game in the series, and the only game that was released in China before this.
Server is now separated into 3 regions: Japan(DX), China(CH), and rest of Asia along with Australia(EX).
Server maintenance for maimai DX is performed everyday, at 4:00~7:00 UTC+8 for China, and 4:00~7:00 UTC+9 for the other two regions.
Aime cards are used for Japan and Asia; the same card can contain data from both regions, saved separately like Taiko. Data transfer from FiNALE is possible in both regions.
WeChat accounts and QR codes are used for China. maimaiDX-net is only viewable from the WeChat official account. No data transfer is possible.
- Interestingly, in the location test at an exhibition, when trying to login with a new account in event mode, the message displayed was "cannot transfer data in event mode".

New scoring system

"Critical Perfect" judgment added. It's equivalent to "Break 2600", except that now it can be enabled for other note types as well.
- "Break 2550" and "Break 2500" are not differentiated however, and shares the Perfect judgment.
- Normal Perfect judgments still give full achievement rate for non-break notes.
- Turning on "Critical Perfect" for other note types is functionally equivalent to the "Judge Style" feature available for the old cab. Therefore, the latter is removed in DX.
"DX score" (でらっくスコア, DX分数 in Chinese) added. It's similar to the EX score system found in IIDX and DDR.
- Critical Perfect = 3 (differentiated from Perfect even if not enabled for other note types)
- Perfect = 2
- Great = 1
- Good/Miss = 0
Max achievement rate is now fixed at 101%.
When transfering data from FiNALE, only scores higher than 100.00% will be re-calculated, with the part higher than 100% being treated as the break bonus score. That's because the exact play results weren't saved; only the scores were saved.
Raw score is now gone; only achievement rate is visible.
Achievement rate is displayed with 4 decimal places instead of 2, making it function like the 1 million score in many music games including CHUNITHM and ONGEKI.
The 2000/1500/1250 distinction of Great judgments for Break notes is now removed. Great judgments for Break notes now always score 80% of the Perfect score, same as other note types. (Until DX1.02-A)
The 100 point bonus of Break notes is counted separately in this new system, compromising 1% of the total achievement rate.
At launch, the scoring of Break notes is as follows:
- 2600 = 1% bonus
- 2550 = 0.5% bonus
- 2500 = 0% bonus

1.02-A update

Ver.DX1.02-A, released on 2019/08/08, changed the scoring to be as follows: (Announcement)
- 2600 = 1% bonus
- 2550 = 0.75% bonus
- 2500 = 0.5% bonus
- Great = 0.4% bonus (unannounced)
- Good = 0.3% bonus (unannounced)
- source
This change was made to decrease the influence that Break notes have on the total score. The exact value was picked because the average of max achievement rates of all charts in FiNALE was 100.49%, and that 100.5% was the border value of rank SSS+.
Chinese and Asian versions use this new scoring since launch.

Touch sensors

Changed mainly to accomodate touch notes. (See the announcement post of 2019/08/07 linked above for a picture.)
C sensor is split into two.
D sensors are added between A sensors.
E sensors are added between A and B sensors.

Note types

Hold

Hold notes can now be released after they end and it would still count as a Perfect.
If released before it ends, the hold note would not disappear, and the player can still press it again. If it was not released for too long, it might still count as a Perfect.

Touch

New. Works like a jubeat marker. It's blue like star notes by default, and is split into four parts, approaching the center to form a square.

EX notes

Exists for all note types except Break. All non-Miss judgments become Critical Perfect, except for EX HOLD.
- For EX HOLD: the starting point is still the same as other EX notes. If not released midway, the ending point is also CP. If released midway, judgment for the whole note might decrease to Perfect or Great, but never Good.
EX TOUCH and EX TOUCH HOLD notes have special graphical and sound effects when successfully hit. Cannot be turned off.
