Instant Transmission Switch [Anarion] - Vega - 07-12-2018
Instant Transmission Switch [Anarion]
NOTE: Only works consistently on Dolphin Emulator.
Works for both online and offline. You can change transmissions/drift-modes live in race. The race/battle starts with a default state of being in Manual. So if you choose Auto and the race/battle starts, you will start off as Manual still until you hit your button activator/deactivator.

RE: Instant Transmission Switch (Offline only) [Anarion] - JoshuaMK - 02-03-2020
Does this address only break offline? Or is it simply that the pointer changes in a way that makes this unusable online?
RE: Instant Transmission Switch (Offline only) [Anarion] - Vega - 02-07-2020
This breaks online. This code doesn't work online but it I think that's because Anarion made it incorrectly. He sets r4 to either 0x12 or 0x02. However, when I broke this address then stepped once, my r4 value is 0x16. It's obvious there are more values, and there's some bit reading going on in the next instructions.

hai jooshua, wen sd ghosts kod??
RE: Instant Transmission Switch (Offline only) [Anarion] - JoshuaMK - 02-07-2020
Thank you. Do you know of any code that only breaks offline? Also, bit 27 is for auto/manual flag. I'm still unsure what bits 28-31 are used for. Bit 20 if set to 1 disables everything except wheelies. Iirc bit 21 is an on/off flag for the end race camera/cpu control of the player (setting this in race sets the camera, but makes your position cease updating) So in theory, XORing the bit should work:

RE: Instant Transmission Switch (Offline only) [Anarion] - Vega - 02-07-2020
It works, updated thread. Added you to credits.
Great job!
RE: Instant Transmission Switch [Anarion] - JoshuaMK - 02-07-2020
The code in the thread doesn't need the 28 type if statement. The code is built so when you press the button, it automatically toggles it on/off/on/off What I put is all that i needed
RE: Instant Transmission Switch [Anarion] - Vega - 02-07-2020
I tried your version initially and there were odd effects going on. Example, every now and then I was forced into a never ending sliding effect.
RE: Instant Transmission Switch [Anarion] - JoshuaMK - 02-07-2020
Weird. I wonder if r12 is reeeally safe. I will do more testing cause I want this to work without 28 type
RE: Instant Transmission Switch [Anarion] - Vega - 02-07-2020
The source for the 28 codetype uses r12 and there's no issues.
I think the issue with your ASM source is that it causes the transmission to switch almost every frame til the user lets go of the button. Maybe this causes some corruption in the game.
