How to update emulator cores (using pcsx_rearmed as an example)

1. set up devkitpro.
2. grab devkitARM r45 and aemstro.
3. grab ctrulib_1.1_mod.
4. grab Retroarch-3DS-Forwarders-PSOne.
5. grab pcsx_rearmed from the libretro repositories.
6. grab HackingToolkit3DS v9.
7. follow core compilation notes.txt instructions and compile pcsx_rearmed to create pcsx_rearmed_libretro_ctr.a and rename it libretro_ctr.a.
8. move libretro_ctr.a to RetroArch-3DS-Forwarders-PSOne.
9. compile RetroArch-3DS-Forwarders-PSOne to create retroarch_3ds.cia.
10. extract retroarch_3ds.cia with Hackingtoolkit3DS.
11. go to rarch3ds_forwarder_creator\tools\assets_ps1 and replace code.bin, exheader.bin, headerexefs.bin and headerncch0.bin with the previously extracted files.
12. open code.bin with an hex editor and find romfs:/game.pbp, note down the address for the first p on pbp.
13. open the version file with an hex editor and modify address 0x10 with the previously noted address. it needs to be written in little-endian (example: 003066D4 becomes D4663000).
14. (optional) while inside the version file, update the emulator core version at address 0x0. it needs to be written in little-endian (example: 04BC5E35 becomes 355EBC04).
15. emulator core should be updated now.
