News module NAND savedata[edit]
- "news.db": This is the main save-file, the filesize is fixed to 0x2BD0-bytes.
- "newsXXX.txt" This is the message data for this notification, where XXX is the decimal notification-index in the below headers-array. The filesize should be <= <size listed here>, since that's the max size read by the notifications applet.
- "newsXXX.mpo" This is the MPO data for this notification if any, where XXX is the decimal notification-index in the below headers-array. The filesize should be <= <size listed here>, since that's the max size read by the notifications applet.

Offset | Size | Description |
---|---|---|
0x0 | 0x10 | Header, see below. |
0x10 | 0x2BC0 (100 * 0x70) | Array of headers for each notification. |

News module startup[edit]
The actual main function called by main() does the following:
- srv_init()
- Registers services "news:u" and "news:s".
- Initializes the service session handle for "ptm:sysm".
- Loads 4 handles from somewhere, which gets used with svcReplyAndReceive later.
- Does notificationID state init, uses SRV:GetNotificationSemaphore, then subscribes to srv notifications 0x104 and 0x106.
- <Some func calls>
- Here PTMSYSM:SetInfoLEDPattern is used.
- Some state init is done, then the usual svcReplyAndReceive loop begins.
Errors[edit]
