List of differences between osu!stable and Classic mod for Taiko gamemode

[chayleaf]

Just putting it in here because it might not be obvious for non-Taiko players

• Scoring. Potentially can be skewed because replays weren't replayed consistently last time I checked even for Lazer replays
• In stable, resolution affects the playfield size, on 4:3 the playfield gets "cut", essentially reducing the note density. Used by many players who can't read high low density and thus can't play on 16:9, used by other players simply to make the game easier (lower note density is easier to read and acc, even if you can read high note density) has been resolved (but the following points remain)
• HR in stable depends on the resolution as well. The base SV multiplier is 1.4, and it gets multiplied by the ratio between the screen resolution and 4:3. For example, for 16:9 it's 1.4*(16:9)/(4:3) = 1.4*16/9/4*3 = 1.4*48/36 = 1.4*4/3 = 1.8666... In fact, this doesn't affect for the fact that instead of the screen width, the playfield width should be used for the calculation to make it fair - which means you see a bit more notes with HR on higher aspect ratios.
• HD in stable is always 4:3. If you play on 16:9, a black bar is put on your screen to hide everything beyond 4:3. I haven't checked what happens if you play on lower aspect ratios, such as 5:4.
• EZ increases the visible HD area, HR reduces it (presumably by scaling the preempt time by the SV modifier). In fact, HR reduces it so much the black bar mentioned above is removed to make it possible to at least see some notes. HDHR is considered by many players to be poorly balanced because of how hard it is for an unprepared player, but higher aspect ratios make it easier.
• Currently, in Lazer, as long as there's an active swell you can't hit any other note. In stable, swells don't block notes which is used in many gimmicks. I think the same applies for drumrolls, but I haven't properly checked it.
• In stable, swells and drumrolls award points but don't result in a judgement (i.e. you can't miss them, get a 100 on them, etc)
• In Lazer, you see a bit more notes on the playfield. It isn't noticable in gameplay, but if you compare screenshots with stable you can see the difference.
• In stable, you can change the volume of "ghost taps", or create fluent swell volume changes. In Lazer, there's only per-note volume, making that impossible.
• Accuracy formula is different (accuracy is higher in general) and ranks depend on perfect hit percentage and whether there are misses, acc is ignored
• Potentially more, that's all I could list off the top of my head

I feel like we're going in circles with new duplicate discussions being made for taiko specifically.

[chayleaf]

I collected everything I could remember here, including some things there aren't discussions for. That said, of course you're free to close some discussions or reorganize it to make it easier to track...

aside from most of this being rehashed for the nth time to the point of tedium as mentioned above, including that entire aspect ratio fiasco and how it breaks mods:

Currently, in Lazer, as long as there's an active swell you can't hit any other note. In stable, swells don't block notes which is used in many gimmicks.

is this used in any maps with a leaderboard? because this potentially sounds like aspire level breakage which is not guaranteed to be ported across.

In stable, you can change the volume of "ghost taps", or create fluent swell volume changes. In Lazer, there's only per-note volume, making that impossible.

this is not exclusive to taiko in any capacity. also see: #13141

Accuracy formula is different (accuracy is higher in general) and ranks depend on perfect hit percentage and whether there are misses, acc is ignored

intentional change

If this is the criteria of porting being necessary, I recommend checking compatibility for all of katacheh's loved maps. In particular, this map has many sliders overlapping notes.

intentional change

I know, but shouldn't classic mod still preserve the old way?

I'm not 100% sure, but the accuracy one might be referring to #9087.

Scoring. Potentially can be skewed because replays weren't replayed consistently last time I checked even for Lazer replays

Care to elaborate? what's about scoring in taiko? and which scoring mode are you referring to? if it's "Classic" scoring mode, you might be looking for #17125 (#17125 (reply in thread) specifically).

As for "replays being skewed", you might be encountering #14573 or #13352.

In stable, resolution affects the playfield size, on 4:3 the playfield gets "cut", essentially reducing the note density. Used by many players who can't read high low density and thus can't play on 16:9, used by other players simply to make the game easier (lower note density is easier to read and acc, even if you can read high note density)

Has since been resolved in #17225 when using the "Classic" mod.

EZ increases the visible HD area HR reduces it (presumably by scaling the preempt time by the SV modifier). In fact, HR reduces it so much the black bar mentioned above is removed to make it possible to at least see some notes. HDHR is considered by many players to be poorly balanced because of how hard it is for an unprepared player, but higher aspect ratios make it easier.

Thoroughly discussed in #14798.

In stable, some transparent skin elements (e.g. drumroll body) are allowed. Whether to allow it in classic mod in Lazer is up to you.

I don't understand the point, what's the problem of it being allowed or not..?

In Lazer, you see a bit more notes on the playfield. It isn't noticable in gameplay, but if you compare screenshots with stable you can see the difference.

Would be helpful to provide the screenshots yourself. However, in the latest osu! release, lazer with "Classic" and stable should be 1:1 in terms of displayed notes (minus lazer having the hit target displayed further away from the input drums).
