[RELEASE] VMP to MCR converter

[Shendo]

I made a small converter to enable easier conversion of PSX saves from PSP.

I know that this is already possible to do with CWCheat but with this program
it is faster and you don't have to start the game in order to convert the save.

this is actually interesting for me, as on my 8gb stick things like cwcheat dont work. What i need additionally though is something to reconvert them back to PSP format - for multi cd discs.

can it convert MCR to VMP

this is good for people that can get cwCheat working

[Jinx13378]

What is VMP format?

[Shendo]

What is VMP format?
VMP files are PSX Memory Cards produced by the PSP.


can it convert MCR to VMP
I'm working on that.
A valid VMP header must be produced, otherwise file won't be recognised by the PSP.

[RedMugen]

thanks for the release man,

i hope you can add the ability of reconvert the MCR to VMP

thanks!

:mad:DUDE... HOw do u use this thing? My psx save files are in .DAT format NOT .VMP. :mad: If you could can Pliz make a tutorail for this Dum###. :DThanks MAN:cool:

[Shendo]

What firmware are you using?
AFAIK .dat is the old PSX PSP save format.

[Zygon_X]

:eek: SORRY dude I got da 3.40oe-a and the psx save files ARE in .vmp, I was looking in my OLD save folders... now the only thing left to do is make it .mcr to .vmp:p...(NEED TO PLAY FF8&9):D

[RobertHMayfire]

How about converting old Dex Drive files? (Ah the good old days.)

Good Luck!!
This thread should be stickied!

But is there a way to convert from .mcr TO .vmp?

But is there a way to convert from .mcr TO .vmp?

To the moment, no. But I hope that Shendo will be able to do this.

Indeed it is the function that more interests to everybody.

[Skyline34]

It was silly of Sony to even change to this '.vmp' format, the original files where much easier to manage :)

So in the future this converter may be able to convert my old 3.30 and under saves to .vmp so i can use them in 3.40+? I still dont know how to use cwcheat to export my old saves then reimport them into 3.52 pops.

[Shendo]

.vmp header contains a checksum of the Memory Card contained.
Seems like only certain parts are used to calculate the checksum.

I don't know what type of checksum is used, if anyone has any information feedback is appreciated.

For now I would be only able to make a injector that will inject a save from .mcr file to the existing .vmp.
The only requirement is that the saves in .mcr must be the same (except the saved data off course).

So if you converted .vmp earlier and you played the game in ePSXe and want to return the save to .vmp it will work.
But if make your own .mcr it "might" not work.

If anyone is interested in this kind of tool I can make it.

I have exactly understood the problem, I Understand the difficulty of realization.

However yes, I hold profit that you add this function.

[Shendo]

If anyone wants to convert .mcr to VMP use this (http://forums.maxconsole.net/showthread.php?t=100282).

Thanks for the work that you do!.:)

[mrericanderson]

Hey the first part worked great. I was able to convert my .vmp to a .mrc- Then i took the converted .mcr file and played it on an psx emulator for a bit. Now I want to bring it back to a .vmp, but its not working. I inject it into the same .vmp and then my psp simly says "no save data" when trying to access it. You said that if it was the same it would work, am i doing something wrong? Or am i going to have to wait for a new version (which is mighty fine by me)

thanks again

[akadewboy]

Use CWcheat (http://www.gamerspress.com/index.php?title=PSX_on_PSP_-_Memory_Card_Handling). It's more reliable.

[mrericanderson]

awesome, yeah for some reason i couldnt get cw cheat 2.0 to work on my 3.71 m33-3, but i ended up using cw 1.9 and its all good now. thanks though! you inspired me to give cw cheat another shot!:):):):):)

[BazPP]

Good stuff..

will give it a try. :)

[Gunbuster]

when you push inject, it asks me for the vmp file again. is this alright like that ? since i already specified the target vmp above

[narc]

I was wondering if it makes any difference if you used the save ID of a different game while making the eboot?

Like, would ePSXe still recognise it as the save file for the right game? And vice versa?

EDIT: it does. :p
Simply involved renaming it as an extra memory card

[Yourfatness]

ive been looking for this forever.

[mokyurin]

Thank you.
You might wanna ask weltall(Creator of cwcheat) for checksum.
He might know something about it.

[Yourfatness]

i was just sitting here copying over my memory cards to keep them both up to date, and i said to myself "wonder if epsxe can read vmp files....nahhh"
but then, for some demented reason, i tried it, and it loaded right up.
try it for yourself, it really works!
it's not a 'recognised' memory card type in epsxe, but it will load them.
NO MORE CONVERTING!!
NO MORE INJECTING!!!
i really found teh converter program useful, but i am the first to discover that it isnt really needed.
SUCK IT!

BTW i am running epsxe 1.6.0 for anyone who wants to know.

EDIT: it's confirmed. i just loaded from a vmp memory card and saved to another. it works, it really works!
go try it! now! NOW!!
ill break your neck!

EDIT2: it worked a few times, but this time i checked the memory card on the psp and it was blank, but when i check it on epsxe, it still showed up.
so, epsxe will read vmp files, and can write to them, but apparently destroy what makes them vmp files and not mcr files.
happy now?
SCREW YOU THEN!!!

[nancom]

Great job!
Thank you, it's help me a lot.

hey, i was wondering if you knew how to get this to work on Final Fantasy 7, because im stuck at one point cause the cutscene doesnt finish, it just stays on the last frame (where barret drops dyne after being shot) and i transferred and converted it on my computer, and got past the cutscene and saved again, but when i used your injector to put it back to my psp, it came up with no saves, so i had to just put my backup on it again and no matter what i try changing around in my popsloader and settings i just cant get past that cutscene, if you can please help, i really need this to work, my old ps1 memory card save was lost when my memory card melted and i wanna complete it on psp this time, thanks
