    Ok,

    I have a pretty rare rom here(for MSX2) which I´d like to inject into a VC .wad file but all attempts to get this working beyond the games main menu screen has failed so far [​IMG] and I did a lot of injections for many systems but this is killing me...

    The game is working on windows with an emulator, the sha1 is ok, I´ve checked it with a romdb.

    After some research I found out that this game uses a special rom mapper in order to work correct, so my plan is to have a look on the emulator included in the VC .wad(knowing after some hex that the emulator is housed in the 00000001.app) which fails to open with u8 tool as its a lz77 compressed file...

    What I want to do is to extract the emulator, add either the rom mapper of the game to it, or a corresponding romdb to get the game to work.

    Now I got wiilz77(came with a wadder release) but how do i use this?

    I have to say that I am not so handy with bash, so a nice, easy to follow tutorial on how to use wiilz77 would be nice.

    Any input on how to use this would be highly appreciated.
    Thx

    Well, for most newer VC titles, the .dol file (the emulator) is compressed as you already know, but not with the normal type of lz77.

    If you a Windows user, maybe try wwcxtool to decompress these, which is found in the wwpacker package. That is what I normally use.

    I hope it works for you.

    I however, do not know anything about MSX rom mappers though...

    Sorry G0dLoKe, i dint explain properlly xD

    I got 2 msx2 games and had a look into "msx2config.bin" (from 00000005.app). Both had diferents values and then i tried changing values using the new injected game. Once using dolphin emulator appear the logo of the game however later the emulator report a error message. It didnt work eader installed on wii

    Well ... i didnt had many time for testing but i will try again this week.

    And about editing unpacked 1.app... i dont have any idea... sorry

    Sure thing.

    This is why I try to edit the 00000001.app to get things working.

    Yeah, exactly, therefore I want to edit the emulator in 00000001.app(dol) or compile a new emulator, like bluemsx with only the things needed to run the game.

    We will also need the romdb.xml somehow included, this is how the emulator verifies the integrity of the rom´s sha1 value in order to check what mapper is needed(mappers are in the romdb.xml

    I assume some kind of romdb must be included in the 00000001.app specified for the corresponding game which is housed in the wad.
