[RM2K3] DYNPLUGINS AND FAILURE MESSAGES MISS, FAIL, AND MORE TROUBLESHOOTING

I dunno if anyone has noticed this in the game Everlong, but how did the creator with the DYN Plugins get other "failure" messages to appear? He somehow got Miss and Fail to appear with some plugins that I can't figure out how he's doing it. That was a thing, in RM2k3, where you could only type one message for "Miss". I am confused how that was done. Anyone have any idea what I'm talking about? 0_0
I'd like to have that in a game I'm doing
