    For encoding a rom for use in the latest versions of
    the Nintendo 64 Virtual Console emulator. Currently
    supported by games such as Cruis'n USA and Kirby 64.

    Usage:
    Encode a rom to romc format
    'romc e input output'

    Decode a romc file back to a rom
    'romc d input output'

    Note:
    Although many roms will save space with compression,
    Some roms will actually gain space instead of saving
    space when compressed due to the algorithm (ex: RE2)

    http://www.megaupload.com/?d=9MJO39BQ

    http://www.sendspace.com/file/3scanb

    Presumably all future versions of the virtual console will use the compressed variant of storing the rom since it allows them to save some block space on roms which don't utilize all of the rom space and contain alot of padding, though the algorithm they used isn't really 'that' great at compression imo, but is aimed at speed I'm sure.

    Thanks for this jurai, it seems we are already heading into the "usability" arena which is nice.

    I'm pretty sure Paper Mario uses compression too.

    I've been trying to inject the Collector's Edition of Majora's Mask into the official MM VC WAD, and the rom needs to be compressed form its full 32MB size to around 27MB (MM VC romc size).
    But when I use the compression tool it reduces the rom to a tenth of it's size (32MB to about 3.3MB) - obviously this is too much (or little, you know what I mean). Any idea why?

    Reason for doing this: I prefer the CE edition of MM to the original, and I don't want to use the GC disc if I don't have to. Obvious;y if anyone has tried this or has any other thoughts other than the actual problem above, do pipe up.
    I've seen Master Quest injection WADs around - presumably ppl managed to pack the GC disc rom into the OoT WAD - was compression involved in that?

    Advice on the compression issue would be handy though.

    TIA and respect. [​IMG]

    Does the new SNES VC WADs use this type of compression?

    If so, adding SNES support would be nice.

    @RadioSHadow: You see that the last update to this app was made over a year ago?

    RadioSHadow: I dont think its the same, Im still trying hard to find soemone to get the NEW LZH8 on snes roms de-/compression, ive asked around a bit but no luck so far [​IMG]

    so if anyone know please reply [​IMG] it has a similar header as the 'old' LZ77 stuff

    eg. 40xxyyzz

    where (40) is the compression type and xxyyzz=zzyyxx = decompressed size of file

    thats the best i can do myself though

    Could someone please re-upload this program since the other links are dead? I'd like to try 32MB Ocarina MQ Debug ROM with the Majora emulator.
