# Wrapper script for SBo o2em package, by B. Watson

# Emulator expects to find ./roms, ./bios, ./voice,
# and its config file in the current dir at runtime.

# Also, it expects the ROM it's running, to reside in
# ./roms, so we have to symlink it there :(

# All of this could have been done by hacking up the
# source, but we want to avoid massive amounts of patching.
