Problems with the option "Record Input"
dink:
Barbudredmon, thanks for the info - that error will only happen if a state is taken during a dma transfer (during cd load - they're very short bursts, so its hard to get a state in that mode), I just made provisions to prevent a problem from happening in that case, though. :) I have to test it later today before commiting - though.
The ZetTotalCycles warning is not a problem, by any means, and can be ignored :)
best regards,
- dink

Hello, Dink.
All the recordings I make are always from a specific point, in Neo Geo just when the Neo-Geo logo appears (so as not to record the green static images of the beginning), and with Neo Geo CD the three times I tried to record , I've done it on the title screen (when it gives you a choice between Game Start Demo Game How To Play). I have also tried saving Save States at the beginning of the round and never doing it during the loading screen.
I just did a test with another game (The King of fighers 94) and the same thing happens, I've started recording from the title screen, and the recording has been desynchronized to the minute.
I hope you find the problem. Thanks for everything and sorry for my bad English.

barbudreadmon, Please try again w/latest git

Neildark, thanks for the info, I will hopefully have a fix soon!

@dink the first crash disappeared, now it's crashing at the end of the ngcd bios :

the libretro cdimgLoadSector function is almost a 1:1 copy of the one at src/intf/cd/win32/cd_img.cpp (the only diff is that i use fopen instead of _wfopen), it seems to be crashing on this line specifically :
--- Code: ---cdimgLBA = cdimgMSFToLBA(cdimgTOC->TrackData[0].Address) + (ftell(cdimgFile) + 2351) / 2352 - cd_pregap;
--- End code ---
Edit : this crash happens because cdimgFile is NULL
Edit2 : FWIW, i tried logging LBA & cdimgLBA values when the function is called :
--- Code: ---LBA : 164 - cdimgLBA : 1
LBA : 164 - cdimgLBA : 15
LBA : 164 - cdimgLBA : 1
LBA : 164 - cdimgLBA : 15
LBA : 15 - cdimgLBA : 15
LBA : 16 - cdimgLBA : 16
LBA : 17 - cdimgLBA : 17
LBA : 164 - cdimgLBA : 15
LBA : 15 - cdimgLBA : 15
LBA : 16 - cdimgLBA : 16
LBA : 17 - cdimgLBA : 17
LBA : 18 - cdimgLBA : 18
LBA : 19 - cdimgLBA : 19
LBA : 20 - cdimgLBA : 20
LBA : 168 - cdimgLBA : 21
LBA : 18 - cdimgLBA : 18
--- End code ---
Then the crash happens, the values doesn't seem to be game-dependent.
