What steps will reproduce the problem?
I would like to suggest a change in savestates. Currently the savestate
contains info about the memcards, so if you delete a save from the memcard
and then load a state, it appears again, only this time corrupt, ruining
your memcard and making it unusable.

What is the expected output? What do you see instead?
If there is no savestate info, this error would dissapear and it will make
smaller savestates.

What version of the product are you using? On what operating system?
It happens in all revesions currently. Using 3914 X64 in Vista.

Please provide any additional information below.
There is a similar feature in Pcsx2, ejecting memcards when you load a
state, thus not corrupting them. This also will make a step forward in the
implementation of TAS.

True, and a nice feature to have if it could be added. Put Xtra as Owner :P.

patch that may fix the memleak, needs more testing

Ok, here are my first tests (also posted in r3999)

1.- Save From Beginning in a Formated Memcard
2.- Load from save without loading a state
3.- Load from save after loading a state (finishing current game and loading save
again without exiting emu)(i.e. in ZWW, after save answer no or in REmake exiting to
main menu)
4.- Load from state and then save after deleting save from memcard (this is the same
as removing your current memcard and inserting a new one,which you could do in a real
5.- Save after loading a state.

                   REV. 3998                     REV. 3999

Game 1 2 3 4 5 | 1 2 3 4 5

REmake Ok Ok Ok No Ok | Ok Ok Ok Ok Ok
RE0 Ok Ok Ok No Ok | Ok Ok Ok Ok Ok
ZWW Ok Ok Ok No Ok | Ok Ok Ok No No
ZTP Ok Ok Ok No Ok | Ok Ok Ok No No

So, in summary, RE problems have been corrected, but in ZWW and ZTP, problems are worse.

If you need more tests I have a couple more games (metroids)

thanks for testing. sms is the same as zelda
I'll probably revert the change for now, until I can determine the correct way to
tell the games that it has been ejected

#7 Updated by lpfaint99 over 11 years ago

forgot to mention: reason zww, ztp, sms are worse is because when loading the state
the first thing they see is the exidummy. RE and other games may not be as picky

#8 Updated by Anonymous over 11 years ago

really exi/si dummy should be disabled by default. It's an invalid device we use(d) in
order to figure things out. So, understandable that games don't like it (maybe part of
the reason why memcards are so finicky in general)

Instead, we should reply there is no device connected and leave it at that.
