I need to verify if there's any existing mod community or specific 737 mod related to "Ixeg." Maybe "Ixeg" is a modder's name or a company. Let me check. A quick search... Hmm, not finding much on "Ixeg 737." There's an "X-EG" mod for MS Flight Simulator, which is the default 737 model. But "Modsfire" isn't a known term in the simming community. The user might have mixed up terms like Mod Fire as a community or Discord server.
