How to get Arcadia working

[MBRetrocade]

Hello everyone so we are looking to get Arcadia working.
Here are the...
Details:
Raspberry Pi 4B w/4GB ram, 64bit processor
Power Supply used: MODEL DCAR-RSP-3A5C, INPUT 100-240V AC, OUTPUT: 5.1V 3.5A
RetroPie version: Raspbian GNU/Linux 10 (buster) - Linux retropie 4.19.97-v7l+
Built From: RetroPie-Setup version: 4.6.1 (4464b474)
USB Devices connected: SNES controller, USB keyboard
Controller used: SNES controller, USB keyboard

Emulator configuration file:
lr-mess = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mess/mess_libretro.so --config /opt/retropie/configs/arcadia/retroarch.cfg %ROM%"
default = "lr-mess"

Retroarch configuration file:

Settings made here will only override settings in the global retroarch.cfg if placed above the #include line

input_remapping_directory = "/opt/retropie/configs/arcadia/"

#include "/opt/retropie/configs/all/retroarch.cfg"

Arcadia listed in es_systems.cfg
<system>
<name>arcadia</name>
<fullname>arcadia</fullname>
<path>/home/pi/RetroPie/roms/arcadia</path>
<extension>.zip .ZIP</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS arcadia %ROM%</command>
<platform>arcadia</platform>
<theme>arcadia</theme>
</system>

It boots back out, do I have the incorrect ROM extensions?
Thank you in advance to those who can provide any insight!
