Forest of Illusion recently uploaded a prototype that was found for iggy's reckin' balls, if anyone finds this kind of thing interesting. They're also looking for anyone who can spot differences:

Thanks for this! So we did find a couple of differences, however, like any emulator, the game crashes. I did submit a couple of findings to Forest of Illusions, hopefully they'll add those soon!
