Yeah, it worked for me without byteswapping it back first. I use romwak from Jeff Kurtz. Just use the /f option.
It seems like it's hitting something in the PLAYER_START routine that doesn't work. I've been referring to freem's documentation here to try to get some insight:
The cart-to-CD conversion process is documented online, but there is no CD-to-cart that I'm aware of. There's probably something simple I'm just not accounting for. I'll bet folks who have written dev environment's like freem's that automatically output a NGCD version of the rom could find the problem pretty fast.
The game crashes at the end of the demo and during coin-up by calling https://wiki.neogeodev.org/index.php?title=BIOSF_VIDEOEN which is only available in the CD bios (for turning spr/bg display on/off -- weird that they go out of their way to use this if the original game didn't?). Doesn't seem impossible to patch out but not as trivial as running some conversion guide online either.
Would be easier if the MAME debugger didn't piss me off...
