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
