Mario Kart: Double Dash (GCN/WIIRD/NTSC-U)

[Rooy.7]

Hi Ralf!

• Code that specifies the items which make the player character laugh when hitting other players with items.

• Code that makes objects on the track unaffected by Thunder when used /Shells, such as Goombas , Piranha Plants & Pokies … etc.

Thanks a lot!

[YoshiWoollyWorld]

Would it be possible to make a code that changes the port colors of each player, such as making P1 blue, P2 green, P3 red and P4 yellow (which changes the colors of everything such as Battle Mode?)

Given the game locks teams into P1 and P2 vs P3 and P4, I’d prefer making teams cool colors (blue and green) vs warm colors (red and yellow)

This can be partially done using Ralf's Kart Number Color Modifier code.

rr = Red   (00 .. FF)
gg = Green (00 .. FF)
bb = Blue  (00 .. FF)
aa = Alpha (00 .. FF)

As an example, I've modified it so odd number karts are red while even number karts are blue.
I have this combined with another code which works for LAN mode's GP HUD (not like it matters though since console order is always randomized)

@YoshiWoollyWorld: I don't think it's possible to make such a code, there're too many elements to patch (e.g. the colored character select frames are .bti image files, the Kart number colors are plain RGBA values and the bomb colors are particle effects etc.).

Hi Ralf,

Would you be able to create a code that forces the two player GP mode HUD to load in 2 player VS mode?
Ideally we'd like the ability to see our race times in a 1v1 race.

Hi Ralf,

The code for the timer works great! Thanks again.

The fireball codes look like a lot of fun to add into a "chaos" codeset.

I'll need to revisit the bob-omb blast codes at some point, there must be some reason why the "number of karts" variable isn't updated correctly when forcing the game mode to load.

Hi Ralf,

The rainbow road SFX modifier works great! There are about 4 stars falling at a time on these tracks, it's easier on the ears now.

One other question I was wondering about, would it be possible to create a bugfix code?
The golden mushroom's expiration timer doesn't count down when a kart is doing the character swap animation.

@pickpickles: Unfortunately, the display routine for the points (the stars) of the Bob-omb Blast Mini-Game is hardcoded to 3 stars for 2 player mode and 4 stars for 3-8 player mode. So it's not possible to display more than 3 or 4 stars (at least with cheat codes).

Tried out both of your required points to win codes, unfortunately neither of them appear to work even if using the default point values you'd expect.
Bob-omb Blast Mini-Game: Required Points To Win Modifier - This one just crashes the game. Bypassing the panic handler causes the battle to end as if 0 points are required to win.
Bob-omb Blast Mini-Game: Required Points To Win Modifier v2 - This one doesn't crash the game, but it ends the battle as if 0 points are required to win.

Interesting to note though that the Always 5 Points Required To Win works on both Splitscreen and LAN mode:

Hi Ralf,

Would it be possible to create a gecko code that causes CPU karts to behave exactly like players?

At the moment, CPU karts appear to behave differently when getting hit by items. If I recall correctly, certain map hazards do not work on CPU karts like the sand pit on Dry Dry Desert. This would fix item related desyncs from getting them to work in LAN mode.

[pickpickles]

Hi Ralf,

Is there a code that can toggle Rumble on or off like the options screen can? Perhaps doable with a button combination and dpad/cstick during a race?

You can disregard the CPU request. It seems that the game's function for syncing LAN player positions doesn't know what to expect when a CPU kart takes damage.

The C-Stick rumble toggle works great on LAN mode with 8 consoles! Players can togggle rumble off for an individual console.

Would you be able to create a code that forces all karts to start in the exact same position? For example, all karts would use the time trials starting position.

Thanks Ralf, I'll give that starting position code a go in LAN mode. That will likely allow playing Multiplayer Time Trials with these codes:
"All Karts Starting Always From Position #1, Item boxes are always disabled, Start with Time Trial Items, Disable Kart Collision"

Any updates regarding the points to win modifier code for Bob-Omb Blast?

I previously did a test with the required points to win v2 code enabled on regular splitscreen. The memory address where the number of players is stored (0x803B1478) does update correctly on splitscreen and LAN, but the code still causes the battle to end immediately.
Perhaps the code is bugged or it's looking at a memory address which isn't 0x803B1478?

[Ralf@gc-forever]

@pickpickles: There was a typo in the v1 and v2 code, the updated codes (in my older posts) should be working fine now.

[pickpickles]

Hi Ralf,

The points to win codes work great now in regular splitscreen and LAN!

Would you be able to update the "Bob-omb Blast Mini-Game: Alt. Points Indicator v2" code? It likely suffers from the same issue that the points to win code had.
A problem with LAN is that the console order is always random when starting a LAN session, is it possible to have the the indicator display the current player's points instead?

[64Mario5]

Hi Ralf,

Could you make another version of the rear view camera code for Mario Kart Double Dash that activates when holding the L button instead of the X or Y buttons?
