ep_nix:ver:bm2dx
Usage: ${_C_scriptName} [EXiV] [opt-args]
Available arguments:
EXiV style (numeric, required)
--cfg launch config tool (spicecfg)
--dbg launch debug environment (--dbg2 if no value provided, available steps through OR blitting 1: spice, 2: x64dbg, 4: wine, 8: style reserved flag)
--root steam library root directory location override (this is where prefixes/runtimes are saved)
--dumps game dumps root directory location override (assuming steam library if not provided)
--exec run anything inside prefix (allows for running any application aside, you may provide arguments after --)
-- arguments past this are passed to executable instead of defaults (read spice etc.)
-h
--help show help
Examples:
${_C_scriptName} 26 --root /mnt/steamhdd --cfg (launches /mnt/steamhdd/steamapps/common/Beatmania IIDX 26/contents/spicecfg.exe)
${_C_scriptName} 26 (launches $_G_root/steamapps/common/Beatmania IIDX 26/contents/spice64.exe)
${_C_scriptName} 26 --exec /tmp/server.exe -- -p 1108 (runs /tmp/server.exe -p 1108 in IIDX26's environment)
${_C_scriptName} 26 --dbg\$((4 | 1)) (launches second example with only additional wine and spice debug steps)
