• Notes on sections like .text1, from Tharo in Discord:

[...] the doldisasm script will name the sections numerically based on the "section headers" in the dol, the proper section names correspond to those numerical names like so:

.init      = .text0
.text      = .text1
extab      = .data0
extabindex = .data1
.ctors     = .data2
.dtors     = .data3
.rodata    = .data4
.data      = .data5
.bss       = .bss
.sdata     = .data6
.sbss      = .bss
.sdata2    = .data7
.sbss2     = .bss

(bss is all the same, because the dol only states where the first bss region starts, and there is no section header entries for the bss sections, so projects using doldisasm usually have to split that out manually, so the bss sections are likely to always be named correctly else the project disassembly probably doesn't build matching yet)
