I only played it through emulation (on ZSNES, in Windows 98!) but I was very young, and I'm a non-native English speaker so the gameplay felt even more obscure to me. It's crazy how now, that I have a better understanding of English, some things I got stuck for a long time when I was a kid were actually quite simple.
The most fun to me, it's that still retains the magic, the OST is still great (and the option to use the classic one is quite a gift), it feels mysterious and magical. They did an amazing job.
So unlike most games today which are mostly a ROM device, SNES games were actual computers on a cartridge.
But I think they were saying the chip in the cartridge this time is faster than the chip in the cartridge last time (which was still faster than the SNES's processor)
