Included in PrismRhythm 19 are a whole bunch of judgment fonts - among which are offered my remakes of the judgments from DDR in higher definition with early/late indicator dashes, as well as other remakes and Ace-original fonts.  This is where you'll find all the necessary information about the judgment fonts I've created (both the DDR/ITG remakes and my own PrismRhythm judgment fonts).  For the DDR/ITG remakes, I did the best I could to emulate the source material; I often managed to get the exact font the original used, and regardless of that, I'd say I broadly came up with very good results.

How to Add or Change Judgment Fonts

If you're using either PrismRhythm 19 or after, or Simply Love, you can make modifications to the list of judgment fonts already present in the theme (you can add new ones, or rename/delete existing ones). How it works is actually pretty simple:

Step 1: Add the judgment font image to the theme's Graphics/_Judgments folder.
(Do include the grid size in the file name here, and ensure it is correct - likely either 2x6 or 1x6.)
(For PrismRhythm 19, alternate choices are offered in Graphics/[Judgment Font Selections].)

Step 2: Add the judgment to your selectable list.
* For PrismRhythm 19, open up Scripts/Other.lua, and add the name of your judgment font to the list.
* For Simply Love, open up Scripts/Theme.lua, and add the name of your judgment font to the list.
(The general name needs to be an exact match; however, do not include the grid size in this list; it only needs included in the image's file name.)

So long as you did these 2 simple things correctly, the theme itself will take care of making sure your new option(s) are on the list and selectable.

Ace Remake Notes: Dance Dance Revolution

For DDR 1st Mix, I don't have the actual original font, nor do I know what the font even is.  The font I used for this remake is Sabo, as it seemed closest.

DDR 2nd Mix's judgment font is known to be Atrox, so that's what I used.

I don't have an image of just the judgments
from DDR 2nd Mix, as the 2nd Mix theme
comes with DDR 1st's judgments for whatever reason.
Trust me, however, when I say DDR 2nd
does actually use a different font.
DDR 3rd & 4th Mix are known to use City as their font, so that's what I used.  The small Os are literally just lower-case.

DDR 5th Mix is well-known to use Black Wolf, so that's what I used.  The small Os are literally just lower-case.

DDR Max 1 & 2 actually use Impact as their font.  Yes, it's true, and pretty undeniable.

DDR Extreme uses a Japanese-enabled font called DFSoGei-W9, so that's the font I used.

DDR Extreme 2 uses Modaerne (Bold) as its choice of font, and that's what I used.  You'll also note I corrected its infamous "Marvellous" 2Ls misspelling.

DDR Supernova uses Apex Commercial as its font.  (A great many iterations of a font called "Apex" are available, but they are NOT the same as this font, nor part of the same family at all.)
DDR Supernova Actual Originals
DDR Supernova Ace Remake
DDR Supernova 2 uses a Japanese-enabled font called DF-Renga-W9, and that's what I have.  The smaller letters are not a natural part of the font itself, but are of course naturally achievable by just making the font size smaller for letters closer to the center of the words.

DDR X1 is known to use Choc D as its font, and that's what I've got.

DDR X2 utilizes Airstream as its font, and I've secured it myself.

DDR X3 vs. 2nd Mix's X3 font is Medfly (Bold), so that's what's in use in my remake.  Starting here, DDR apparently no longer likes using "Almost" in favor of calling that a Miss as well, so I brought it back, in the way it would probably look if present in the original judgment fonts.
DDR X3 Actual Originals
DDR X3 Ace Remake
DDR A1 is very well-known to actually use a very customized font (one of the only times they've ever bothered, actually), to give it a slightly wider look with sharper edges; thus, there simply doesn't exist a DDRA1 iteration of said font, so I got as close as I could by using Handel Gothic (Standard Heavy), the commonly-available font that their customizations are hypothesized to be applied to.
DDR A1 Actual Originals

DDR A2 started really phoning in the judgment fonts again here; A2 uses the font Baskervville (yes, with 2 Vs).
DDR A2 Actual Originals
DDR A2 Ace Remake
DDR A3 uses perhaps the most phoned-in looking font of all, Helvetica Narrow (Bold).  I think it looks so generic, but that isn't my fault; that's what they used, so that's what I used too.

DDR World, at the time of this writing, anyway, has not been out all that long.  Research is still ongoing by the internet to discern which fonts have been used for various parts of the game, but in the meantime, the closest I've found is Black Han Sans.
DDR World Actual Originals
DDR World is new enough at this time
that I don't have a theme reference sheet.

Ace Remake Notes: In the Groove

ITG1 uses Black Friday as its font.  The original also did not use early/late dashes (the only ITG game whose official judgment font does not do so); thus I added them into my remake.
September 29, 2024 Remake Fixes: Fixed vertical centering.
ITG1 Actual Originals
ITG1 Ace Remake
ITG2 uses Xenotron as its font (though it's usually a rather wide font, so it's technically squished some horizontally).  There wasn't particularly a need for me to remake this, as it's perfectly serviceable in StepMania 3.95, but I bothered anyway.
September 29, 2024 Remake Fixes: Sized up; fixed vertical centering; fixed coloration for Excellent.
ITG2 Actual Originals
ITG2 Ace Remake
ITG3 uses SF Sports Night as its font (and is the only font to use a 3D effect in the original).  That's what I have, but I'm not very skilled at applying 3D effects, so I did what I could with other effects to mimic what I saw in the original.

PrismRhythm

PrismRhythm Ver. 1 was the very first font I ever created back when the theme was in its infancy stages, and was the default font for my PrismRhythm theme all the way from pre-2013 PrismRhythm 9 antiquity, through PrismRhythm 12 in 2017.  This isn't the heavily-pixelated original (which was also actually WordArt) - rather, this is a high-definition remake done up in PhotoShop as accurately as I could manage, so anybody with nostalgia goggles can use it.  The font is Arbuckle Remix.
PrismRhythm Ver. 2 was the first judgment font I'd made in PhotoShop.  This was the default font for my PrismRhythm theme for about 7 years, all the way from PrismRhythm 13 (in 2017) through PrismRhythm 18, only being retired as its default font in 2024 when PrismRhythm 19 was released.  The font that I had used here was VAG Rounded BT.
PrismRhythm Ver. 3 is the current default font for my PrismRhythm theme, introduced in PrismRhythm 19, crafted in 2024, and actually the first I applied an outer glow effect to (it only took 19 iterations of the theme for me to decide that would be a good idea).  The font is Bauhaus 93.
