This is a command line tool. As such, basic command line usage is assumed. if you don't know how to use the command line, then you should look up how.
Usage is "nedcenc [options]"
[options]
-i <Input file> (Required)
-o <Output file>
-e Encodes bin dotcode files to raw (-o option required) (default)
-d Decodes raw dotcode files to bin (-o option required)
-f Fixes dotcode raw files.
-s <Signature> There are either 40 or 44 bytes unused in a dotcode raw
file, depending on if the raw is for a long dotcode or
short dotcode. You can input any string or hex value.
to input spaces, quote the string or use <20>. To insert
quotes, use <22>. To insert <, use << or <3C>.
To input any hex string, start with <. then input the
hex string, then end with >.
Example.
"<<Dotcode encoded by> -=<<CaitSith2><65027110>"
If -s is not specified, dotcodes will be filled with either
<2425262728292A2B2C2D2E2F303132333435363738393A3B3C3D3E3F>
<404142434445464748494A4B4C4D4E4F> (short)
or
<38393A3B3C3D3E3F404142434445464748494A4B4C4D4E4F50515253>
<5455565758595A5B5C5D5E5F> (long).
Offset Size Description
0x000 1 xxxxyyyy - xxxx unknown, yyyy region
0x001 1 xxxxyyyy - xxxx card type, yyyy unknown
If the region is 0 or 2, then all titles/text have to be in shift-jis format. If the region is 1, then all titles/text are in ascii format.
Offset Size Description
0x000 0x0C Header
Valid application headers
x = don't care
A = number of cards
B = card number
C = Data length * 2
D = Application Type - 0 = GBA/Z80 type, 1 = NES type
E = Individual card title mode bit
F = Permission to save bit
xxxx0000 - Jap original (will also run on Jap plus)
xxxx0001 - US
xxxx0010 - Jap plus
001xxxxx - Pokemon name/stat mode, load music A
010xxxxx - Pokemon name/stat mode, load music B
1110xxxx - Longer title mode, load music A
xxxxxxxx xxxxxxxx AAABBBBx CCCCCCCA CCCCCCCC 00000010 00000DEF 00000000 00000000 00000000
If the type is 2,3,4, or 5, then the Maximum title length is 16 characters, Otherwise, if it is E, then the maximum is 32 characters. The header format is identical between the two.
If the card is in individual card title mode, then the number of titles that have to follow the application title depends on how many cards are in the set. If the number of cards in the set exceeds 8, no individual card titles are displayed, instead, the ereader logo is displayed. Even though this is the case, you still have to specify the individual card titles. Therefore, it is best not to use this mode if the set is going to require 9 or more cards. What might fit on 8 cards in normal title mode, may just require 9 cards in individual title mode, depending on how many bytes are required by the compressed application vpk data.
Formats 2,3,4,5 - Card titles follow a format of 3 bytes stats, followed by an 17 character title.
ABBBCCCC DDAAAAAA EFFFFDDD
0 654321 - Order of A bits
210 - Order of B bits
3210 - Order of C bits
10 432 - Order of D bits
0 - Order of E bits
3210 - Order of F bits
A = ID: 01-99,A0-A9,B0-B9,C0-C8 (x-AA-x)
B = ID: A-G,# (x-xx-B)
C = HP: 10-150. A value of 0 means no HP is displayed.
D = ID: A-Z,-,_,{HP},.,{ID},: (D-xx-x)
E = Stat display control. 1 = no stat display.
F = unknown.
Format E - Card titles are 32 bytes each.
If the title is NULL, and there is only one card in the application, then the application is started immediately, upon successful scanning. A NULL titled application cannot be saved, as the e-reader treats that as having no application on the save.
If the vpk length - 2 immediately follows the vpk data, then the application is either Z80 code type, or NES code type, depending on whether the Application type bit was set or cleered. However, if the vpk length - 6 follows 4 bytes of 0s, then the vpk data, the application is GBA code type. The application type bit must remain cleared.
The max number of application cards is 8 on the original japan ereader, and 12 on the US ereader and Japan ereader plus.
The original jap E-Reader does not support the GBA/NES application types. Title formats have to always be individual title mode. Z80 application controller input is on a different register. Title length in short title mode is 4 bytes less. Those 4 bytes must be 0 filled.
- Functions ported to nedclib.dll. (Source code available seperately)
- Added signature option
- Encoding bin2raw is now default operation.
- Initial release.
- (No longer need to use VBA e-reader for encoding needs)
