This Build tool option allow to add an application signature to binary data (right after the header).
:: Add application signature to binary data (0=false, 1=true) set AppSignature=1 :: Application company set AppCompany="GL" :: Application ID (0~65535) set AppID=0
Application's signature is 4 bytes long and composed of:
- 2 bytes for the company/group/creator name (a 2-character string like "MX" for example),
- 2 bytes for the application number (any value between 0 and 65535).
If 2-character string is recommended for group name and integer for application number, in fact, both of those parameter can be any of:
- 2-character string ("MX" for example),
- 16-bits decimal unsigned number (1234 for example),
- 16-bits hexadecimal number starting with 0x (0x0750 for example).
Some company string are reserved:
| String | Company's name |
|---|---|
| "AB" | Konami (Boxing and Football) |
| "CD" | Konami (many games) |
| "EF" | Konami (Pennant Race and Knightmare 3) |
| "JP" | Johan (?) |
| "GH" | Reserved |
| "gl" | MSXgl Samples |
| "PP" | Pixel Phenix |
| "YZ" | Konami (Game Master 2) |
| "XX" | Reserved |
Application signature is put just after the binary header:
- At ROM start address +0010h,
- At Basic binary start address +0007h.
