AppSignature

This Build tool option allow to add an application signature to binary data (right after the header). The signature format is inspired by the meta-data that Konami used to identify its cartridges and add cross-game options.

:: Add application signature to binary data (true or false)
AppSignature = true;

:: Application company
AppCompany = "GL";

:: Application ID (0~65535)
AppID = 0

Application's signature is 4 bytes long and composed of:

• 2 bytes for the creator/group/company code name (a 2-character string),
• 2 bytes for the application number (any value between 0 and 65535).

If 2-character string is recommended for creator code and integer for application number, in fact, both of those parameters can be any of:

• 2-character string ("MX", "a7" for example),
• 16-bits decimal unsigned number (1234 for example),
• 16-bits hexadecimal number starting with 0x (0x0750 for example).

Application signature is put just after the binary header:

• At ROM start address +0010h,
• At Basic binary start address +0007h.

You can also add extra data using AppExtra option. WIP
