Hi!

Aluigi, Can you decript the text file?

Most of the data is compressed with LZSS and afterwards encrypted with a really tricky encryption.

I upload German and English files.

Thanks!

I think I found the C code for decode.

Aluigi. Can you do the Quickbms script for decode/encode the "ATDS.TAP" file, please?


decrypt(data, chunk->size);

void Resource::decrypt(byte * data, uint32 size) {
byte* c = data;

for (uint i = 0; i < size; i )
{
*c = -(*c);
c;
}

I have the next wrong Quickbms script to decode texts:

get header long
get resType short
get chunkCount short
for i = 0 < chunkCount
get size long
get type short
savepos OFFSET
xmath NEXT_OFF "OFFSET size"

encryption math "n #INPUT#"
#log "" OFFSET size

filecrypt 1
# wrong part starts here
getdstring DUMMY 0x18
do
slog "" -1 -1
getdstring DUMMY 5 #7???
savepos TMP
while TMP < NEXT_OFF
# end of wrong part
filecrypt 0

goto NEXT_OFF
next i

Please, Can someone do it better?
