Summary	06240: pdrift: Game reboots when you finish Course B
Description	When you end the Course B winning all races game reboots. Sometimes it happens that the emulator crashes. Rarely the game behaves correctly ending with the Extra Stage. It is random. Strangely as far as I test the game works properly with the Course E that ends successfully with Extra Stage with no problems .
Steps To Reproduce	Win all races of the Course B

There are cheats enabled for this game however I'd rather not resort to that in the attempt to reproduce the reported behavior. Will try and practice more in the coming days.

In multiple attempts I usually start to lose sync somewhere during 3rd or 4th race.
No.12791 mahlemiut Developer Jun 21, 2016, 00:16	The INP doesn't playback for me either. I think you may have NVRAM present, which is causing issues for the rest of us trying to play it back. Could you make an INP without anything in the nvram/pdrift folder?
No.12795 Scagazza Tester Jun 21, 2016, 08:44	I have tried to record another inp after deleting nvram but it doesn't work, it goes out of sync during playback. Sorry
No.12796 Tafoid Administrator Jun 21, 2016, 11:44	Perhaps you might be able to do a save state before the game reboots or randomly crashes as you mention - it would give Developers something to work from. As of now the chances of debugging this are low until we get a good crash/stack crawl/backtrace and having a save state just before the event would help greatly.

No.12798 mahlemiut Developer Jun 21, 2016, 22:05	You have to remove NVRAM for playback also. Otherwise you can't get a consistent state for the INP to start from.
No.12813 B2K24 Senior Tester Jun 26, 2016, 01:52	acknowledging for now while the reported behavior can be investigated and discussed.

No.12946 Scagazza Tester Jul 16, 2016, 14:54	I have just finished to check all the course: A always crash B random crash C always crash D no crash E no crash
No.12955 NekoEd Senior Tester Jul 17, 2016, 18:39	Might the INP issue here be related to 06301 by any chance?
