# iris.toml — IRIS emulator configuration
# All paths are relative to the directory you run iris from.
# Command-line flags override any value set here.

# Run without graphics: no window, no REX3. Independent of audio.
# Can also be set with the --headless command-line flag.
headless = false

# Disable audio emulation (no HAL2). Independent of graphics/headless.
# Can also be set with --noaudio.
no_audio = false

# PROM ROM image (required).

# Window scale factor: 1 = native resolution, 2 = 2× for HiDPI/4K monitors.
# Can also be set with the --2x command-line flag (CLI takes precedence).

# RAM bank sizes in MB.
# Each bank must be 0 (absent), 8, 16, 32, 64, or 128.
# The SGI Indy supports up to two populated banks; banks 2 and 3 are
# typically absent.  Total RAM = sum of non-zero banks.

# SCSI devices.
# Valid IDs: 1–7.  The SCSI controller itself occupies ID 0.
# Typical Indy layout:
#   ID 1 — internal hard disk
#   ID 4 — internal CD-ROM (removable, 512-byte block mode)
#   ID 6 — optional second hard disk or tape

# Port forwarding rules — forward host ports into the guest (IRIX).
# proto:      "tcp" or "udp"
# host_port:  port to listen on on the host

# bind:       "localhost" (loopback only, default) or "any" (all interfaces)

# Example: forward host TCP 2323 → IRIX telnet (23), localhost only:
