EmuTOS most definitely supports AUTO folder programs.

However, it seems that it doesn't respect the bootdrive so you need
to remove any GEMDOS drives from your configuration to use it,
otherwise it boots from C:, not A:.

(This will mean that Hatari GEMDOS tracing cannot be used, I'll
report this issue to EmuTOS developers.)

Did you use Hatari's tracing facility for verifying the arguments
(with normal TOS), or something else?
