Code doesn't work properly for me. The CP display is stuck from the beginning of the race and doesn't update when new checkpoints are reached. I'm on dolphin, so that may be the issue :/

[Vega]

Were you in Solo TT or an online VS race?

What version of Dolphin are you using? Are you using a modified codehandler?

Do you have the option 'Store XFB Copies to Texture Only' disabled in your Graphics settings?

[Jeffy/Wrath]

I tested it (NTSC-U and NTSC-K) and it gets stuck at 35 (on MG) at the start and doesn't update.

Are you on Dolphin? If not, how are you loading your cheats. I remember making this and had no issues during testing.

[Jeffy/Wrath]

Im on dolphin, im using the dolphin code loader thing (in the game settings > Gecko Codes.). I have XFB off, I can test on wii if you want

[Vega]

Try it on any HBC app that uses the original Gecko 1.9.3.1 code handler (ex: any version of USB loader GX). Go on Solo TT or online, and see how it goes.

[Jeffy/Wrath]

works fine on wii (tested on Gecko 1.9.3.1, NTSC-J, VBI Hooktype) so its just a problem with dolphin

[JoshuaMK]

its updating an instruction, try flushing the cache on that address and it should fix the bug

Ty Josh.

here's a new version for anyone to try
