drg2sbg's Introduction

This program takes a .drg file from I-Doser and convert it to an .sbg SBaGen file.

The authors of this project have nothing to do with I-Doser, I-Doser is a registered
trademark.

This project does not supports piracy or any illegal action, the use of this product 
must be stricly to pass .drg files to .sbg for later convertion to .wav or similar 
portable format, for those who (as the author) doesn't have a Windows pc to play the
dose.

This project will never be possible without the help of "The Unofficial I-Doser Blog"
and their _steAlth_'s DRG Author by konstAnt and _khAttAm_ to tell the truth this is
a rip off stripped version of konstAnt and _KhAttAm_ _steAlth_'s DRG Author. They did
all the work with the .drg files, I just port some parts of it to C.

Features:
* Convert drg file into sbagen format
* Extract every part of the drg file (description, title, image, sbagen code)
* Create drg files

drg2sbg's Issues

alloff in place of all-off

This program will output alloff: inplace ofall-off: -`. The cause of this was not apparent via inspection of the source code.

help porting to javascript

I am working on a port of this to javascript for a HTML5 idoser player.

I can't get mine to output the correct stuff & wondered if you could help. I think I have pretty accurately ported drg_get_uncoded_data, mine looks like this:

function drg_get_uncoded_data(data){
    var S = [
         22, 213, 140,  67, 234,  48, 108, 225,   6, 101, 194,  50,  44, 247,

        240, 130,   8, 180, 106, 172,  83,  12, 146, 251, 226,  53, 153, 107,
        199, 248, 187, 5
    ];

    var i = j = s = temp = 0;

    for (var b = 0; b < data.length; b++) {
        i = (i+1) % 256;
        j = (j + S[i]) % 256;
        temp = S[i];
        S[i] = S[j];
        S[j] = temp;
        s=S[i] + S[j];
        data[b] = data[b] ^ S[s % 256];
        console.log("b=%d, i=%d, j=%d, s[i]=%d, s[j]=%d, s=%d: %s (%d)", b, i, j, S[i], S[j], s, data[b], data[b].charCodeAt(0));
    }

    return data;
}

data param is base64-decoded chunk for the element.

I get this for title of Absinthe.drg:

b=0, i=1, j=213, s[i]=168, s[j]=213, s=381: 1 (49)
b=1, i=2, j=97, s[i]=13, s[j]=140, s=153: � (148)
b=2, i=3, j=164, s[i]=54, s[j]=67, s=121: q (113)
b=3, i=4, j=142, s[i]=96, s[j]=234, s=330: � (138)
b=4, i=5, j=190, s[i]=244, s[j]=48, s=292: + (43)
b=5, i=6, j=42, s[i]=74, s[j]=108, s=182: � (148)
b=6, i=7, j=11, s[i]=50, s[j]=225, s=275: T (84)
b=7, i=8, j=17, s[i]=80, s[j]=6, s=86: ' (39)
1�q�+�T'

I modified your for-loop to look like this:

for (b = 0; b < a; b++) {
        i = (i +1) % 256;
        j = (j + S[i]) % 256;
        temp = S[i];
        S[i] = S[j];
        S[j] = temp;
        s=S[i] + S[j];
        data[b] = data[b] ^ S[s % 256];
        printf("b=%d, i=%d, j=%d, s[i]=%d, s[j]=%d, s=%d: %c (%d)\n", (int)b, i, j, S[i], S[j], s, data[b], (int)data[b]);
    }

and it (correctly) outputs:

b=0, i=1, j=213, s[i]=168, s[j]=213, s=381: A (65)
b=1, i=2, j=97, s[i]=13, s[j]=140, s=153: b (98)
b=2, i=3, j=164, s[i]=54, s[j]=67, s=121: s (115)
b=3, i=4, j=142, s[i]=96, s[j]=234, s=330: i (105)
b=4, i=5, j=190, s[i]=244, s[j]=48, s=292: n (110)
b=5, i=6, j=42, s[i]=74, s[j]=108, s=182: t (116)
b=6, i=7, j=11, s[i]=50, s[j]=225, s=275: h (104)
b=7, i=8, j=17, s[i]=80, s[j]=6, s=86: e (101)
Absinthe

Everything seems to match up to the actual char output, for some reason. Any help you can provide would be much appreciated.
