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! 💛💛

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.

Code: Select all

Kart Number Color Modifier (3D & HUD Track Indicator) [Ralf]
043B1380 rrggbbaa - Kart  1 (Default: FF5A5AFF = Red)
043B1384 rrggbbaa - Kart  2 (Default: 006AFFFF = Blue)
043B1388 rrggbbaa - Kart  3 (Default: 00FF00FF = Green)
043B138C rrggbbaa - Kart  4 (Default: FFFF00FF = Yellow)
043B1390 rrggbbaa - Kart  5 (Default: FF80FFFF = Pink)
043B1394 rrggbbaa - Kart  6 (Default: C87124FF = Orange)
043B1398 rrggbbaa - Kart  7 (Default: 00CAF2FF = Cyan)
043B139C rrggbbaa - Kart  8 (Default: 9D4CFFFF = Purple)
043B13A0 rrggbbaa - Ghost 1 (Default: 9696FFFF = Orchid)
043B13A4 rrggbbaa - Ghost 2 (Default: A0A0A0FF = Grey)

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)

Code: Select all

043B1384 006AFFFF
043B1388 FF5A5AFF
043B138C 006AFFFF
043B1390 FF5A5AFF
043B1394 006AFFFF
043B1398 FF5A5AFF
043B139C 006AFFFF

@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.).
