RE: Camera Toggle - Vega - 07-09-2019
Since NTSC-J is not working atm, the code will be in this subforum for the time being. Btw, you can make this a C0 codetype (for the first ASM only) instead of using a OSSleepthread subroutine address.
Also, I recommend keeping the code structure the same way for all regions (even though this will you cause you to use an unneeded extra instruction for controller button loading on U, J and K), and use macros to change values that are region dependent. Trying to work with multiple sources doesn't make any sense.
For why the Japan version is not working, that is something wrong with the source. As the ports for the OSSleepthread have been testing on multiple codes countless times. I doubt you messed up porting the address that has the nop. You will need to step by step the japan version in Dolphin to fully diagnose. Have you done step-by-stepping before? This one will be weird cause one address is called nonstop, so you may need to set an instruction BP on the other address (the nop), I'm guessing that address is the one that gets called when track loads???
Anyway good luck with fixing the Japan version. I'm out of town cuz of work so I won't be much help....
And nice code!!

Btw, you can make this a C0 codetype (for the first ASM only) instead of using a OSSleepthread subroutine address.C0 Is a good idea. Didn't think of it. Also, I went and completely rewrote the Custom Laps code, not only making it about 5-6 lines shorter, but I also lifted the limit from 32769 laps to +60000 laps by changing the cmpwi instructions to cmplwi insructions. Also, the input number now reflects what lap you will be on when laps start counting instead of following a complicated equation.

RE: Camera Toggle - Vega - 07-09-2019
First thing's first. I checked every port for every address (address of ASM, address of ur nop, address of camera height, address of camera distance), and they are all Good.
I did some changes to your source, and made it more organized. I also rerouted some non-optimized branch routes, and added branch hints. So when you compile this, you will need to change the region letter at the top for each version you compiled (it is left blank at the moment). They will all compile slightly different. Ofc, don't forget to remove the 0x3E80 & 0x0880 from the compiled code for the user's controller stuff, and don't forget to test this with your 32 bit nop.
I'm still out of town, so I can't actually test this in game.
If you want to change this to a C0 (assuming this new source works on all regions after tests), you just need to change your use of r4 to r5, then remove the vannila instruction (leave the label name there, you can end sources with a label name). For C0 codes, select the C0 option in PyiiASMH before compiling.
Anyway, here's the source...

RE: Camera Toggle - JoshuaMK - 07-09-2019
It still doesn't work on NTSC-J. Also I was looking, and it seems to crash well after the code, to the point to where I got to impatient to continue after 5 minutes of stepping code. It also crashes in the form of getting stuck in an infinite loop rather than the hardcore 00000300 crash...
I think I am going to start playing around with registers
RE: Camera Toggle - Vega - 07-09-2019
It appears the floating point RAM changes in NTSC-J causes a bad floating value, which causes an invalid instruction somewhere, then causing a crash and you end in an infinite loop (i know the one you are talking about). There's a few things to try.
Some options....
1. Change the address of the 1st ASM, you can use the Millisecond Display Modifer address so the actual floating point changes to RAM don't start til the timer starts. If it still freezes at track load on JAPAN, then its something with your nop. Ofc, you are nopping some branch, follow the branch again, and double check what you are skipping/not skipping.
2. Try a different set of floating values, if it works on Japan. Then change them for other regions and retest U, P, and K. If all good, it's just something you will have to accept, idk how much time you want to dig into this rabbit hole.
3. Try #1 and #2 with old source first!! Just in case I botched the new source.
--
Also here's a side note when dealing with offset values greater than 0x7FFF when you wanna load from a memory address set by lis...
Let's say you want to load a word value from 0x8045C21C. To load this without using an ori instruction, just increase the lis value by 1, then sign extend the offset value. Like this...
lis r12, 0x8046 #8045 plus 1
lwz r12, 0xFFFFC21C (r12) #0xC21C sign extended
Try that out for future codes.

RE: Camera Toggle - JoshuaMK - 07-09-2019
Nevermind the milliseconds timer keeps camera from being able to toggle when it shows your lap time after crossing onto the next lap. Any other ideas?
RE: Camera Toggle - Vega - 07-09-2019
Use the address that the Universal Meter uses.
