BLO is a format used to define layouts in Gamecube games, such as Super Mario Sunshine and Luigi's Mansion. There are two versions of BLO, which are marked as blo1 and blo2: differences will be noted between the two formats.
File Format
The file begins with the string "SCRN" in ASCII.
blo1/blo2
Right after the SCRN magic, the blo section is described.
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | File magic. Always blo1/blo2 in ASCII. |
| 0x04 | UInt32 | File Size. |
| 0x08 | UInt32 | Number of sections. |
| 0x0C | Byte[0x10] | Padding. In blo2, this is an empty SVR1 section with 0xC bytes of padding (0xFF.) |
INF1
INF1 stores basic information on the layout.
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | Header magic. Always INF1 in ASCII. |
| 0x04 | UInt32 | Section Size. |
| 0x08 | UInt16 | Layout width. |
| 0x0A | UInt16 | Layout height. |
| 0x0C | UInt32 | Tint Color. (RGBA) |
PAN1/PAN2
PAN defines a null panel.
PAN1
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | Header magic. Always PAN1 in ASCII. |
| 0x04 | UInt32 | Section Size. |
| 0x08 | Byte | Number of parameters. |
The parameters are defined right after. The are in the following order:
| Offset | Type | Description |
|---|---|---|
| 0x09 | Byte | Is Visible. |
| 0x0A | UInt16 | Padding. |
| 0x0C | String | Panel name. String is always 0x4 in length. |
| 0x10 | UInt16 | Left? |
| 0x12 | UInt16 | Top? |
| 0x14 | UInt16 | Panel height. |
| 0x16 | UInt16 | Panel width. |
| 0x18 | UInt16 | Angle. |
| 0x1A | Byte | Anchor. |
| 0x1B | Byte | Alpha. |
| 0x1C | Byte | Inherit Alpha. |
PAN2

BGN1
BGN1 begins all child panel data.
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | Header magic. Always BGN1 in ASCII. |
| 0x04 | UInt32 | Section Size. |
END1
END1 ends all child panel data.
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | Header magic. Always END1 in ASCII. |
| 0x04 | UInt32 | Section Size. |
