If I had to make a guess, the Sports Mix game most likely uses hex byte values to represent character values. Chances are Mario will be a value of null (0x00).

Go to the character selection in the game (fyi Ive never played this game before so bare with me), and choose Mario. On Dolphin-memory-engine, run an Exact search for Hex Byte 0x00. You will probably get over 1 million results. Now navigate back to character selection again, choose something other than Mario. Now some options on the Memory Engine program will be changed. Click the drop down menu that's underneath Byte, select "Changed", and hit Continue Scan.

After that scan has completed, back out and choose Mario. Change the drop down menu option to Exact Value. Make sure the value is still on 0x00, hit Continue Scan. Back out to Character selection yet again, choose something other than Mario. Select "Changed" , hit Continue Scan.

Basically you're swapping between Mario (0x00) and other Character (Changed value) over and over to narrow down the lists of results. Eventually you will get to a small enough list to watch in real time as you select the Characters and see the values update. At that moment decide which Address you want to set  Write Breakpoint. Once the Write BP is set, back out to Char selection, choose a Character, and the BP should hit. You will have a Hook Address with a Default Instruction to make a code with.

It's possible Mario isn't the value of 0x00. The character at the top left (or set on default selection) might be 0x00. You will have to tinker around with this and do some guesswork for the initial values being used for your search.

In other words, without going too far, for example, in Mario Kart Wii the Mii cannot be controlled by the CPU (but that already comes by default) but only by the player (us), in this case I would like to make a code so that Rosalina ( just to give an example) cannot be controlled by the CPU, this would imply that she would not appear in the Grand Prix or VS races.

It's that I really want to create various codes for various Wii games.

If you force me to take a guess, the Wii Sports Mix Game probably uses some table in memory where the CPU's assigned character values get written to sometime right before an event takes place, then those values are read during event load up. If such a case exist, you could find a way write a code to make sure a particular value will never get written to said table.

First I recommend attempting the method I've described to see how successful you are in forcing Character selection. You need to get some experience under your belt.

(04-10-2023, 03:18 PM)Vega Wrote: That is indeed too many results. Now that you have all the character values, this should help narrowing down to a manageable list. Retry the method but do something like this..

Select Luigi search for 0x01, go back
Select Toad, continue search but with value 0x09, go back
Select Moogle, continue search but with value 0x0C, go back
etc etc til you get a small enough list

If that doesn't work, you can slightly change the method...
On the character selection screen...
pre-select Luigi (don't actually select/click on him), search for 0x01
now pre-select Toad, change value to 0x09, continue search
now pre-select Moogle, change value to 0x0C, continue search
etc etc

That code is checking a pointer (memory address value) located at 805c1c04. It will then use the pointer there (which will vary) to use as a storing reference.

The old mkwii license unlock codes are setup in a similar fashion

https://mariokartwii.com/showthread.php?tid=639

This code has a similar structure. Scroll down in that post you will see an ASM equivalent I've made. That will give you an idea of what is going on in such a code.

Either way these pointer codes are tough to port sometimes. Your best bet would be to get the version of the game for that code. Launch that game to character selection. Then go to 805c1c04 in a memory viewer. Find a nearby string to use as a porting constant and attempt to manually port. You won't be able to use or include the contents of 805c1c04 as part of your string for porting because the contents there always varies. Hopefully that makes sense.

(04-12-2023, 07:14 PM)LightKingdom666 Wrote: But from what you say, apparently it is quite a complicated code to be created from scratch, which already says enough, considering you're more advanced than me, I think that I cannot even consider myself at least as a beginner (much less than that), the code I created was just my first code, and I had no idea how to create code until I came across your post.

In the same way, I will try to do what you told me to do (try to port the code to my version), and the last thing you mentioned about the best thing to do would be to try to get the version of the game for that code, it would not be an option for me (the code is PAL), since my Wii (yes, i still have one) is NTSC-U, and I want to have all the codes that I create/modify exclusively for that version, so I prefer the first option.

(04-12-2023, 07:14 PM)LightKingdom666 Wrote: But hey, changing the subject in case portability doesn't work, I have another idea for another code (I suppose this should be easier), in Mario Sports Mix there are 2 teams, blue (you) and red (CPU), each team has a bar to do a special attack, said bar has 5 levels, and when those 5 levels are completed you can perform the special attack.

Well, the idea is to create a code so that the bar of the blue team (you) is always full, while the bar of the red team (CPU) never fills up, I also forgot to mention that for said bar to fill up varies depending on of sports, in Basketball it fills up when you throw the ball, in Volleyball when you catch the ball, in Dodgeball when you throw the ball, and in Hockey when you throw the puck, all this 5 times (because as I said before, that the attack bar specials has 5 levels, and 5 is the maximum).

It goes without saying that the idea already exists (yes, I mean, there are already codes for that), the downside is that none of them have worked for me (in any version, just to be clear), here I post them, it's not a code with many lines, so maybe I assume it's easier:
