Nintendo Modern Arcade games (Excel binaries)

Post by LolHacksRule »

I'm trying to figure out the binary parameter files in Nintendo's Arcade games since and past Mario Kart Arcade GP DX. It appears to be some type of excel file in a binary form (my guess would be CSVBIN due to LM Arcade's executable mentions such a file). I attempted to doc a small portion of the format, I think I did. I will add samples soon.

Code: Select all

//------------------------------------------------
//--- 010 Editor v10.0.2 Binary Template
//
//      File: Nintendo Modern (2011+) Arcade CSV binaries *.MATTR (LM), *.BIN, *_PARAM.BIN, *.ABT, *.NGW (LM), *.VMD
//      Authors: LolHacksRule
//      Version: 1
//      Purpose: Gets some data out of the scripts.
//      Category: Deserializing
//      File Mask: excel_header
//      ID Bytes: excel_header
//      History:
//------------------------------------------------

char    excelHeader[12]; //657863656C5F686561646572 (excel_header)
char    unk[1]; //MKDX appears to have this set to 02 on some files, primarily 00, might be version idk
char    padding[3]; //should be 20
char    paramCount[2]; //How many param values are present in the file
char    morePadding[7]; //Should be seven nulls
char    aValue[1]; //Float, or string afaik

Just a suggestion, remember to add the samples in a new post because if you edit the original post it will not be visible, or if you edit it then also make a post to bump the topic.
