Since the game doesnt let you delete your progress and I looked trough the files of the game to find any indication of saved data, i still couldnt find anything. So that means that the speedrun of this game can also be done on an already completed save file. Since there is (yet) no way to erase save data.

So, in any% now Im wondering if you should be allowed to use the cars you unlock in the challenge modes, beceuase im uncertain. So i think ill make it so that you can only use the first 3 cars ( since you can use them from the beginning on ) and if you want to use the other cars, you need to complete the challenge modes (even if you already completed them off run ) so we dont have any advantages over someone for example who didnt complete the game yet. I hope we will find a way to erase save data soon.

Since there hasnt been a reply and im wondering the same thing, Im asking again because i would really want to try running DIE on the 3DS. So could that be a thing?

i did not record my RTA as i drove the races. So that would then mean i cant submit the run as i understood correctly? And i also dont know how its counted when you look your times up on records. So only the loading times dont count or is just the time of the laps summoned up and the records show your total? Because the loading times in mkds are pretty much always the same on original hardware. So would it be possible to just add the loading times to the total of the IGT to get the RTA or would i have to make a new run and my old one (with only the IGT) would not be accepted? Sorry if i could not explain my question because im not that good in english but anyway thanks for your help

on mkds you can look through your time on records. I got the times for each cup and when i compared my time to others it was surprisingly good. But would it be enough proof for the time? Because i play on an original ds lite and there is no easy way to record the gameplay without the use of an emulator. So would it be allowed?
