Talk:SELF File Format
psp2swu.self
By looking this reference (http://www.sco.com/developers/gabi/latest/ch4.eheader.html) seems that the self data is written for 32 bit, instead of 64 as i should expect. anybody knows why?

Well the question is for sure long time answered but the Vita CPU is a 32 bit one.

Authentication ID
Offset 0x80 in the SELF header. SceWebCore
has 0x8000 set; the only system app with that flag set.
sceAppMgrConvertVs0UserDrivePath
checks the authentication id to limit mount points.
0x2800000000008003
seen used by SceWebCore can only access vs0:data/external/cert/
and vs0:data/external/webcore/
0x2800000000008004
seen used by games and 0x210000101CD20007
seen used by PSM can only access vs0:data/external
and vs0:sys/external
Relocations
Offset | Size | Description |
---|---|---|
0x0 | 0x4 | Relocation Type |
0x4 | 0x4 | Long entry: Addend |
0x4 | 0x4 | Short entry: 0-19 = Bits 10-29 of offset, 20-31 = addend |
0x8 | 0x4 | Long entry: Offset |
Relocations can be of two types: 8 byte "short" entries or 12 byte "long" entries. The relocation code is the same as ARM ELF format.
Segment start = Buffer address of segment indexed at "Patch segment"
Symbol start = Buffer address of segment indexed at "Symbol segment"
Address to patch = segment start + offset
P = address to patch
S = "Symbol segment" == 15 ? 0 : symbol start
A = addend
Relocation Type
Start | End | Description |
---|---|---|
0 | 3 | Short entry if set |
4 | 7 | Symbol segment |
8 | 15 | Relocation code |
16 | 19 | Patch segment |
20 | 27 | Long entry: Optional relocation code 2 |
28 | 31 | Long entry: Optional distance 2 |
20 | 31 | Short entry: Lower 12 bits of offset |
