The main reason for the emu check was to force you to test the game on real hardware and report bugs if you find any. There were no complaints, so I assume it’s working as it should. In future versions there won’t be any emu checks anymore.
Dasi is right, the graphics are from the arcade version, and only the music is from the PC Engine version.
By the way, with the tools provided by MK, it wasn’t that hard to create this mod.
So if you like this game and want to support this and MK’s other projects, I would suggest making a donation to him.
