This seems unlikely. many related bugs have been fixed in nightly. I am able to specify a directory "BatteryÖ"

Just run it with all your files in c:\temp\desmume

Next time, don't use anything but English letters and numbers in your windows name (NO SPACES EITHER) and you will avoid many application bugs and other inconveniences.

You can also make a symbolic link from c:\Users\PÖÖR CHOICE to c:\Users\BetterChoice. open an administrator command prompt and enter this:
mklink /d c:\Users\BetterChoice "c:\Users\PÖÖR CHOICE"

ADD it
but make it look like this
[General]
BackupSavestateSuppress=1

That's what RAM SEARCH is for. This is also called "cheat finding". You can find a lot of information about that online. Many people use "Cheat Engine" for PC games, but "RAM SEARCH" is built-in here. The techniques are similar.

That procedure was correct. if it doesn't work then the .dsv is broken or you're mixed up about which dsv belong with which rom.

view > magnification filter, perhaps

if you know it happened when you touched something in the 3d settings, then nobody can help you but yourself. change each option and keep careful notes so you can do it systematically.

save in-game and close the emulator. open the emulator, load the game, and load the in-game save.
The time will now be updated

YOU be more specific. I can hardly understand you and had to guess a lot.

uint32 ARM9_ReadWord(u32 address) {
//insert above normal processing:
if(address == cymv_interested_in_it) {
   if(it's_a_good_time_baseD_on_other_conditions) {
     printf("put a breakpoint here.")
   }
}
//normal processing goes here...
//switch(addr) { case REG_GPU_THIS: return 22; case REG_SPI_THAT: return 109; }

}

oh, sorry, mac version may not make backup savestates.
in that case use "time machine" or other backup software.
If you don't have backups for important documents, reconsider your life choices.

StateSlots\Name of game (backups)

1. put the script in freelook.lua alongside desmume.exe
2. dearchive this contents alongside desmume.exe https://sourceforge.net/projects/luabin … p/download
3. run desmume, tools, lua scripting, new lua script window. browse, find freelook.lua

DO NOT USE SAVESTATES; save in-game, close the emulator, change the system date, then open the game and load your save file. That should work.

Sorry, the GPU code is enormously huge. I doubt it's impossible to pin it down to any one place.
But since you seem technically adroit, let me advise you of the slick way of doing the bit shifting.
248 would have been 31<<3 so you can get back from 248 to 31.
Now, the slick way is to do (31<<3)|(31>>2) which uses the MSB of the source value to populate the bottom 3 bits of the destination value instead of just leaving them at 0.
I understand you need to do the REVERSE of that, probably. Hence: just mask off the bottom 3 bits
New version 255 & ~7 -> 248.
