Hello team,
I have been working with my friend ChatGPT and he told me the following.
What do you think? Is it right?
If it is not correct, please present an alternative and the argument that supports it.
Thanks in advance,
Best regards

Summary of Configuration Changes for Atmosphere on Switch | ChatGPT 4o:
Objective: Maintaining the my current configuration of EMUNAND with Atmosphere, we have to configure everything for the launching of SYSNAND with Atmosphere on a Nintendo Switch
with the following conditions, within
the SYSNAND with Atmosphere instance:
- Disable all programs in the \atmosphere\contents folder.
- Allow online play (no blocking of Nintendo servers).
- Access all sections like news, update games, and firmware automatically without issues.
- Prevent Nintendo's telemetry services from collecting any data related to Atmosphere.
- Make Nintendo's telemetry services to do his things with any amendment from Atmosphere.
- Ensure that the only functionality of Atmosphere is the ability to run Homebrew on-demand (in the very end I only want to use JKSV and Reboot-To-Payload to go back to Hekate from SYSNAND).

Empty.
3. \atmosphere\config\exosphere.ini
- Create separate versions to be selected with a script:
- exosphere_emummc.ini for EMUNAND, as it currently is.
- exosphere_sysmmc.ini for SYSNAND, as follows:
[eupld]
upload_enabled = u8!0x1 ; Allow uploading error reports to Nintendo (Permitir la subida de reportes de errores a Nintendo)
[usb]
usb30_force_enabled = u8!0x0 ; Use default USB 3.0 configuration (usually disabled) (Usar configuración por defecto de USB 3.0, generalmente desactivado)
[ro]
ease_nro_restriction = u8!0x0 ; Do not ease NRO validation restrictions (No relajar la restricción de validación de NROs)
[lm]
enable_sd_card_logging = u8!0x0 ; Disable logging to SD card (Desactivar el registro en la SD)
[erpt]
disable_automatic_report_cleanup = u8!0x0 ; Allow automatic error report cleanup (Permitir la limpieza automática de reportes de error)
[atmosphere]
fatal_auto_reboot_interval = u64!0x0 ; Do not auto-reboot after a fatal error (No reiniciar automáticamente después de un error fatal)
power_menu_reboot_function = str!normal ; Reboot normally from the power menu (Reiniciar de manera normal desde el menú de apagado)
dmnt_cheats_enabled_by_default = u8!0x0 ; Disable cheats by default (Desactivar cheats por defecto)
enable_hbl_bis_write = u8!0x0 ; Disable BIS partition writing from HBL (Desactivar escritura a particiones BIS desde HBL)
enable_hbl_cal_read = u8!0x0 ; Disable CAL0 partition reading from HBL (Desactivar lectura de la partición CAL0 desde HBL)
fsmitm_redirect_saves_to_sd = u8!0x0 ; Do not redirect save files to SD (No redirigir las partidas guardadas a la SD)
enable_am_debug_mode = u8!0x0 ; Do not enable AM debug mode (No activar el modo de depuración en AM)
enable_dns_mitm = u8!0x0 ; Disable DNS interception (Desactivar la interceptación de DNS)
add_defaults_to_dns_hosts = u8!0x0 ; Do not add default DNS redirections (No agregar redirecciones DNS por defecto)
enable_dns_mitm_debug_log = u8!0x0 ; Do not enable DNS MITM logging (No activar el log de DNS MITM)
enable_htc = u8!0x0 ; Disable htc (Desactivar htc)
enable_log_manager = u8!0x0 ; Disable log manager (Desactivar el log manager)
enable_external_bluetooth_db = u8!0x0 ; Do not redirect Bluetooth database to SD (No redirigir la base de datos de Bluetooth a la SD)

applet_heap_reservation_size = u64!0x8600000 ; Reserve default heap space (Reservar espacio de heap por defecto)
4. \atmosphere\config\system_settings.ini
- Create separate versions to be selected with a script:
- system_settings_emummc.ini for EMUNAND, as it currently is.
- system_settings_sysmmc.ini for SYSNAND, as follows:
[exosphere]
debugmode=0 ; Disable debug mode (Desactiva el modo de depuración)
debugmode_user=0 ; Disable user debug mode (Desactiva el modo de depuración para el usuario)
disable_user_exception_handlers=0 ; Do not disable user exception handlers (No desactivar los manejadores de excepciones)
enable_user_pmu_access=0 ; Do not allow user PMU access (No permitir acceso a PMU por el usuario)
blank_prodinfo_sysmmc=0 ; Do not blank PRODINFO in SYSNAND (No blanquear el PRODINFO en SYSNAND)
blank_prodinfo_emummc=1 ; Blank PRODINFO in EMUNAND (Blanquea el PRODINFO en EMUNAND)
allow_writing_to_cal_sysmmc=0 ; Do not allow writing to CAL0 in SYSNAND (No permitir la escritura en CAL0 en SYSNAND)
log_port=0 ; Disable logging via port (Desactiva el log por puerto)
log_baud_rate=115200 ; Log baud rate (irrelevant if log_port=0) (Velocidad de log por puerto, irrelevante si log_port=0)
log_inverted=0 ; Do not invert log (irrelevant if log_port=0) (No invertir el log, irrelevante si log_port=0)
5. New script/payload creation: \bootloader\payloads\emummc_sysmmc_config.bin
- This payload is a script, converted into binary, that copy the correct configuration files before Atmosphere launches.
@Echo off

What We Achieve with These Modifications
- Different Settings for EMUNAND and SYSNAND: The ability to maintain distinct configurations for EMUNAND and SYSNAND in Atmosphere by using separate configuration files (exosphere.ini and system_settings.ini) that are automatically swapped based on the NAND mode selected.
- Online Play in SYSNAND: Ensure that the SYSNAND mode is safe for online play, with telemetry from Atmosphere being completely neutralized.
- Controlled Atmosphere Features: Disable all unnecessary features of Atmosphere in SYSNAND, ensuring that the only active functionality is on-demand Homebrew execution.
- Protection of Nintendo Services: Ensure that updates, news, and other Nintendo services work normally in SYSNAND, without any interference from Atmosphere.
By implementing these changes, you can use your Switch safely online in SYSNAND mode with Atmosphere, while still having the flexibility to use more advanced features in EMUNAND.
