Sorry, fixed.

@

Dan Salvato , would there be any chance you could fix the widescreen hack so that the off screen bubbles are in the 16:9 region instead of the 4:3 region?

I looked into this in the past and didn't succeed. I may revisit it in the future.

check the update in the reddit thread, melee is specifically at a super weird aspect ratio he didn't take into account so codes are re-updated. it's not the biggest change, from my naked eye, but it's still a bit more accurate

Code:

16:9 for tv’s:
xxxx = 4080, yyyy = 4040
16:9 for monitors:
xxxx = 4200, yyyy = 41c8
16:9 for dolphin:
xxxx = 4260, yyyy = 421c
4:3 for dolphin:
xxxx = 4160. yyyy = 4150

Im still confused, whats the differences between the 3 different widescreen codes?

The two different codes are for the two different versions of Melee. The XXXX/YYYY are replaced depending on the type of display you're using. They are all slightly different aspect ratios.

mirrorbender · Apr 7, 2015

Hey Dan, thanks for posting this so that more people can find it (and for giving me my credit). RazzleDazzle, the difference has to do with the area of the screen that is actually game image in all 3 scenarios. For dolphin, it's the entire screen. On 16:9 monitors with a console, it's less because the wii/cube adds pillar-boxing on the sides, so the actual game image doesn't take up the whole screen. On (most) 16:9 TV's, the display area is the same as 4:3 TV's (which includes some, but not all of the pillar-boxing, I think), so the original code that just multiplies the FOV by 4/3 works as intended.

The PAR is weird. The first set of codes was based on math and the proportions of the console's display that are game image vs pillar-boxing vs horizontal blanking, so I believe that mathematically, they should have been correct. However, someone mentioned that many games use non-standardized PAR's, so I did some testing. I based the updated codes around what made the geometry look right, specifically by measuring the height and width in pixels of the character selector token in high res dolphin screenshots, and finding a ratio that made that the most perfect circle. Interestingly, not all circles in melee have the same proportions. The stage selector pointer and the smash logo on the stage select screen are proportionally wider (very slightly) than the CSS circles, and the circle on the screen display options screen is significantly narrower. Because of this ambiguity, I don't think it's possible to get more precise without knowing what the HAL intended the PAR to be when designing the graphics.

*Edit: First smashboards post hype!

Hey guys little OCD update here. I have decided that the best benchmark for a perfect circle is the shield, rather than the CSS token, because a) it is a 2D sprite, so there are no weird perspective transformations going on, b) I know it is supposed to be a perfect circle (the shield sprite is 128x128), and c) because it is actually a part of the gameplay and not a menu item, and the gameplay is the most important part to get looking perfect. So with that in mind, I did some more measurements in dolphin and came up with a new PAR of 23:21. This is accurate to within a pixel at 1080p in dolphin. So the new (and hopefully final) values of XXXX and YYYY are as follows:

16:9 Dolphin: XXXX = 42B8, YYYY = 427C
16:9 Monitor: XXXX = 4438, YYYY = 440E
16:9 TV: Same as always XXXX = 4080, YYYY = 4040
4:3 Dolphin: XXXX = 41B8, YYYY = 41A8

You should find a way to implement that into 20xx or that netplay build.

I'm so tired of seeing those super wide shields.

mirrorbender @

Dan Salvato What are the default values, as in making the code do absolutely nothing?

mirrorbender · Jul 2, 2015

If the two values set to be the same, the code should do nothing. It is multiplying the FOV by the XXXX and then dividing it by YYYY (which are each hexadecimal floating point numbers), so if they are the same XXXX/YYYY = 1, and nothing should change.

Hey mirrorbender. I love using your widescreen code, but I found an issue with it.

This was using the 16:9 code for monitors, on 3.02 20XX, and recorded using my elgato. This type of issue never happened during singles; only during doubles and happened on one other occasion (also when changing the port from CPU to Off). As you can see, it is quickly fixed, but I thought I'd let you know. I'm unsure if this is due to the code not working well with 20XX, and I have not tried this on a regular Melee ISO.

Edit: It might have to do with this "small bug" from the hack pack

It might be a bug with the code? I've played doubles on Dolphin with 20xx 3.02 in widescreen and sometimes (even without making a nametag) it will do that randomly. Only in doubles though.

mirrorbender · Jul 8, 2015

Yeah, wierd bug. My first guess is that there is some kind of conflict with the registers being used to load the FOV multipliers. I didn't write the original code, @

Dan Salvato did, so maybe he has more insight as to what might be causing it. It definitely could just be a 20XX problem.

Dan Salvato · Jul 8, 2015

I've never seen that happen so it might just be an issue with the 20XX Hack Pack. I'll do some testing, I guess.

CeLL · Aug 1, 2015

@

mirrorbender How does your Dolphin PR affect this code?

mirrorbender · Aug 3, 2015

Good question. Dolphin's "Force 16:9" option now lines up with what a TV displays, so the "TV" version of the code works best with that. If you are stretching the aspect ratio to fill a 16:9 monitor, then the old "dolphin" version is still best, but I'd actually recommend using the "TV" code in combination with "force 16:9" and dolphin's crop setting if you are trying to fill a 16:9 monitor, just so you don't have to be continuously switching codes.

Also, I'm working on another option for dolphin that dynamically calculates the aspect ratio based on the projection matrices that the gamecube sets up, so whenever that is completed, using that setting will be able to intelligently correct the geometry for any aspect ratio code that is being used, so look out for that sometime this month.

As always, I'll try to answer any questions that come up about proper usage, because this stuff can get very confusing very quickly if you lose track of what's going on.

I've made this code and a slight variation of it available for all game versions in the Melee Code Manager (it'll now be included by default in all future versions). Here they are if you want to add them to your library yourself. Once copied to a text file in your Mods Library folder, it will appear in the program where you can toggle it on/off in your game.

16:9 Widescreen Support (Variation A)
Includes the fullscreen flashing effect fix.
This variation also fixes the position of magnifier bubbles, but also stretches the HUD.

If using with Dolphin, you'll also need to change the setting, "Force 16:9" for the aspect

ratio and make sure "Widescreen Hack" is OFF.

Notes: these are codes for the dol file, not for the RAM address.

My post above yours also has the code converted for different game versions and for going into the DOL, it's just in a different format, which works with the Melee Code Manager.

If someone adds the code with the offsets you've given, it might overwrite custom code for a different mod and cause a crash (simply depending on what the user already has installed - or it could interfere with what they might install in the future, unless they take certain precautions). The difference between adding the code to the DOL using MCM, is that MCM adds codes to the DOL based on what other codes/mods are also installed, adjusting the placement of all code accordingly, to ensure that none overlaps. It also of course avoids the work of finding offsets and calculating branches, or doing any manual hex editing.

Brandondorf9999 · Jan 9, 2017

Here's one that should be included in the Melee Code Manager which I removed one of Dan's injection mod code for 1.02 as that one stretches the HUD which shouldn't be stretched. That code was edited at 2F0560 by that user.

This variation also fixes the position of magnifier bubbles and unstretches the HUD.

I just thought I could be nice and have this aspect support put on the Melee Code Manager since this adjusts the field of view and that perfectly in-game:

Code:

-==-


Aspect Ratio + Field of View Adjustment
Fixes everything including the view of the trophy in "gallery" mode to run the game with perfect aspect ratio support such as for widescreen mode.

Unlike other variations, this also allows for field of view adjustment.

The key legends alter the following aspect/fov angles:

XXXXXXXX - Horizontal Aspect Ratio (1st Static Overwrite)
YYYYYYYY - Vertical Aspect Ratio (2nd Static Overwrite)
ZZZZZZZZ - Field of View (3rd Static Overwrite)

The fov is increased if the value is lower than 1 (3F800000).

If you are calculating the horizontal aspect ratio, the key is to divide the original 4:3 ratio float "1.333333333333333" by your aspect ratio decimal value, then convert it into 4 byte hex. (Example: 1.333333333333333  1.777777777777778 = 0.75 --> 3F400000)

As with the vertical fov, multiply the aspect ratio by 0.5625.

(Example: 1.333333333333333  0.5625 = 0.75 --> 3F400000)

Note: You'll need to use a lower float value to extend the aspect ratio/fov.

It's only for 1.02 for now, but I'll make this for other versions later.

Here's a new version of the MCM hack with support for versions aside from NTSC-U (v1.02).

Aspect Ratio + Field of View Adjustment V2
A new and decent version of the aspect/fov fix. This time it properly fixes the name-tag display to fit the screen.
