You don't need a Neo-Geo plugin. Those bytes you're looking at in IDA are actually part of the M68K's vector table.
https://wiki.neogeodev.org/index.php?title=68k_vector_table
This table is, conveniently enough, used to find what you're after: the starting address of the ROM as a 4 byte address. The first 3 bytes of it are actually in your screenshot at address $0004 and on (looks like $0000FF?? replace the ?? with whatever byte is at $0007). Jump to that address to disassemble the real start of the game's program.
