umm well unless the Original Chipset could "secretly" display 8 bitplanes and 32 pixel wide sprites, yes it is AGA only. Maybe it runs on an A500 (I never tried), but the graphics would be a bit screwed up.
What are you running it on? Maybe an emulator automatically detects and switches. I can assure you I am using features that are, at least, documented only for AGA.
