G1M picture files are similar to
capture-files. Instead they hold
two bitmaps, which are overlayed when displayed in the FX-9860G (using the
standard picture load). They have a constant length of 0x084C. Pictures start
at offset 0x004C.
0x10 bytes are one line. That’s all. One has to keep track of the picture
number.

| Offset (b) | Size (b) | Description |
| 0x20 | 0x10 | main_ID; "PICTURE nn"; nn = 0x31 0x00...0x32 0x30 (1-20); zero padded |
| 0x30 | 4 | MCS_SubItemCount; usually 1 |
| 0x34 | 8 | MCS_DIRNAME ("main"; zero padded) |
| 0x3C | 8 | MCS_ITEMNAME ("PICTnn"; nn = 0x31 0x00...0x32 0x30 (1-20); zero padded) |
| 0x44 | 1 | MCS_DirType (0x07) |
| 0x45 | 4 | MCS_DataLength; hint: the datatype "int" fails because of bad alignment (0x800) |
| 0x49 | 3 | Unknown purpose (maybe 4-alignment), appears insignificant |
| 0x4C | 0x800 | 2 images |
