    Finally managed to guess the required keys to pack a savefile using segher's tools... And packed a modified savefile for international karate...

    Modified the original file so as to start with a c64 basic screen... which is a snapshot from my custom frodo application...

    Here is the demonstration video

    Made the test using basic screen but of course all snapshots taken with my custom frodo can be transferred to wii this way...

    LOAD"$",8 pressed enter... it gave FILE NOT FOUND ERROR
    SYS 64738 pressed enter

    That part came as improvised actually at the end of the video since I was too late to stop the recording...
    It would be better if I resetted the emulator so to activate original International Karate snapshot again...

    Sorry for rising the dead from the ground...

    With triiforce (with nand emulation) you can accomplish the stuff in the video a lot easier..

    Here is the steps, I assume you got the snapshot for PAL international karate game.

    1. Create a custom snapshot using the custom frodo

    2. If you got the dump of the international karate game, you should have a savefile.dat in folder title0010001\43395950 in your nand dump. Open the savefile.dat file in a hex editor.

    3. Copy the whole contents of the custom snapshot and paste it at the start of the savefile.dat, and save..

    4. Now open international karate... press close button so that the snapshot in savefile.dat is restored... now you can play your custom snapshot in the wii vc emulator...


    ps1: you can get the ik.fss file custom frodo needs in reverse, simply copy the first 68.928 bytes from the savefile.dat to a new file and save it as ik.fss.

    ps2: here is an example snapshot : http://www.tepetaklak.com/data/fistrem.rar , game is in the public domain by the way.

    here is a link for more such games that are put into public domain by their publishers :http://www.c64gg.com/dls.html
