"Double Dash!!" Speedometer [Sponge]

A remake of the speedometer from Mario Kart: Double Dash.

Preview:

I've aimed to make this behave and look accurate to the original game, although it's not perfect.

Stars and Bullet Bills both have unique color animations, this was inspired by CTGP-7.

File modifications are needed for this to work. A zip with assets will be provided so you can add them to your own game files.

I made this as a proof of concept. I'm certain this can be optimized in the future.

Note: This code uses addresses 0x80001610 through 0x8000161E. Ensure no other codes read or write to these addresses.

Where do we add the assets files

Thank you so much for the speedometer, Sponge!
I was looking for a mod like this for years, imo, the Double Dash speedometer fits MKWii very well Big Grin

Apologies for the overly simplified answer beforehand.

You need to locate the file Race.szs in files/scene/ui (You need to unpack the game with Wiimms ISO Tools), once you do, make a backup of Race.szs, unpack the Race.szs with Wiimm's SZS Tools (Specifically the wszst tool iirc, you should get a Race.d folder), add the files provided by Sponge in the respective sub-folders (Race.d/game_image). The provided files don't replace anything, they are add-ons, so don't worry about any replacement. Compress the extracted folder back into Race.szs with the same SZS Tools, and then repack the game with the ISO Tools.

EDIT:

1) In case the speedometer appears out of place (In my case it appeared in the low centermost part of the screen, and only the upper half of the speedometer was visible -I'm using a modded game with LE-CODE v32-), you need to edit the file speedometer.brctr with Wexos's Toolbox to correct the speedometer placement.

2) if you are using Dolphin and the game crashes every time you enter into a race, then make sure that in Dolphin, both the options Enable MMU and Pause on Panic (in Options/Configuration/Advanced) are unchecked/deactivated, if you do this, then you will have only 1 warning message in the first race you play, every time you turn on the game, just click on Ignore and you're golden Big Grin

MKWii-Martin · 10-11-2024, 03:18 PM

Sorry for the triple-post, but I need the visibility so hopefully the issues I'm gonna report get addressed.

I'm using the NTSC-U version of the game extracted with SZS Tools, it has LE-CODE binaries (?) and I launch the game by drag-n-dropping main.dol via Dolphin, the code is likewise added to Dolphin's Gecko code list, with this said:

-The UI first appeared in the lowermost center part of the screen, and only the upper half was visible, I had to correct its position with Wexos's Toolbox

-When I am about to start the first race in a game session, I get this warning:
Invalid read from 0x00000000, PC = 0x808E6AB0

-if I choose to ignore the warning, I can play normally as if nothing, and the warning itself will only appear once, every time the game is turned on.

-The above can be dealth with without problems, but this code causes conflict with other codes, namely Track Music Expander, Ultra UnCut,
Skip Ghost Selection Screen, All Items Can Land v2, and Disable Slipstreaming, maybe other codes I don't have, as well.

-If I place the MKDD Speedometer code above all of the aforementioned codes, these codes lose functionality, and if, instead, the MKDD Speedometer code is below these codes, the UI doesn't even appear

I know that the description mentioned that the code would cause conflict, but this speedometer is way too good to let it go, and I hope that the code is made in a way that ensures maximum compatibility, if even possible.

That's it, have a nice day.

-The above can be dealth with without problems, but this code causes conflict with other codes, namely Track Music Expander, Ultra UnCut,
Skip Ghost Selection Screen, All Items Can Land v2, and Disable Slipstreaming, maybe other codes I don't have, as well.

-If I place the MKDD Speedometer code above all of the aforementioned codes, these codes lose functionality, and if, instead, the MKDD Speedometer code is below these codes, the UI doesn't even appear

I know that the description mentioned that the code would cause conflict, but this speedometer is way too good to let it go, and I hope that the code is made in a way that ensures maximum compatibility, if even possible.

That's it, have a nice day.

I will be honest and say I have no idea why these issues occur for you. The code has been tested on all regions (ithe video showcasing the speedometer was done on NTSC-U and both NTSC-J/K were verified to be working from other people, PAL I verified myself). The code conflicts sound like user error to me because I use multiple codes myself and have no issues. If you can, please try this without using a CT-distribution or any LE-Code patches and let me know if these issues still occur.

Okay, will do, I'll give it a go within this week.
About the speedo itself, maybe I'm installing the assets in a wrong path?
I did install the assets in Race.szs/game_image/subpaths, and the speedo does show up and work fine, like in the video, but I only have the warning.

As long as you merge the "game_image" folder with the one in "Race.szs", you should be fine.

I made tests with the repacked ISO of a completely vanilla game (with the speedo assets added and speedo code active, of course), both with no other codes active, and with all codes I have along with the speedo code, everything worked perfectly, with the only exception mentioned below.

The only code I have that caused a conflict with the speedo is the All Items Can Land v2 code.

If the speedo code is used along with the code above, and the speedo code is sorted below the above code in Dolphin's Gecko code list (even if these 2 codes are the only ones active), the speedo's animation when using star/bullet/shroom stops working, it instead only changes the color of the speedo depending on the item being used, and it also looks bugged.

This happens with both the standard version of the code, and the code modification posted by a coder named Unnamed in post #4 in that code thread.

Hopefully this helps, so thank you a lot for your time, much appreciated.
