# Kickstart and Workbench:
|
|
# - If toolchains/emulators/support/kickstart.rom is present, it is
|
|
# used as the Kickstart ROM. Otherwise FS-UAE's built-in AROS ROM
|
|
# is used (less compatible with OCS Intuition but requires no
|
|
# licensed files).
|
|
# - If toolchains/emulators/support/workbench.adf is present, it is
|
|
# inserted into DF0: and the Amiga boots Workbench. The user
|
|
# launches the example from the JOEYLIB drawer on the desktop.
|
|
# - If Workbench is not present, AmigaDOS boots directly from DH0:,
|
|
# executes s/startup-sequence, and auto-runs the requested example.
|
|
#
|
|
# Always on A500 hardware (OCS chipset). Our HAL only uses OCS
|
|
# features so this matches real-hardware behavior.
