Corrupt Save States (some games)

[GoogleCodeExporter]

What steps will reproduce the problem?
Try this.  Record a save state in Double Dragon II.  Then exit the game, 
play a different game, THEN exit.  THEN play Double Dragon II again, and 
load the save state.  The graphics will be corrupt.  Also happens with 
Teenage Mutant Ninja Turtles.  However, with TMNT, you can pause the game, 
then un-pause and graphics wont be corrupt anymore.  Could also happen 
with other games, I haven't tested all of them.

What version of the product are you using?
2.0.7. 

It happened all previous versions as well.

Please provide any additional information below.

Don't know why some games have corrupt save states, but fixing this would 
really make alot of us happy!  Thanks!

I checked and this happens for me too. But could you check with FCE Ultra 
0.98.12 
and see if it happens there?

@dborth.

I noticed that now with version 2.0.8 the save states for Teenage Mutant Ninja 
Turtles are no longer corrupted.  BUT, the save states for Double Dragon II ARE 
still corrupt.  Slight improvement.

I noticed that too, that's why I left this issue open. Thanks for the 
confirmation.

I get repeated corrupt states with Little Samson as well.  So this appears to 
be 
random games, not any specific ones.  Interesting!

I can confirm this happens with MegaMan 3 too. Wish to see this fixed soon. :)

Old Issue... so far these are my findings:

1) This is not an issue of corrupt save states. The save state files are 
correct. 
This can be confirmed by loading them on the PC version.

2) The real issue is related to the moment of LOADING the save state. For some 
reason the sprites displayed at the time the game is loaded are kept in the 
video 
buffer, and the emulator utilizes them to present the loaded screen.

3) If the sprites loaded in the buffer are renewed, the display becomes fixed. 
This 
is for example when you change levels in a game. That is why in some games it 
becomes fixed when the user pauses/unpauses the game.

4) It might be fixed by clearing the loaded sprites buffer when a game is 
loadad, so 
the sprites already there won't exist after loading causing the jerkyness.

I have finally successfully updated the core to FCEUX 2.1.0a, that has fixed 
this 
issue.

Saves of FCEU-GX v3.0.6 do NOT load in v3.0.7.
