It's the only Amiga to have crystal clear sound (low-pass filter cutoff is above human hearing range). Not to mention that it takes up little space, and offers...

Bad idea, in my opinion. Should make something from scratch instead of butchering a classic module by converting it to 4 (or 3?) channels.

How do I calculate the checksum? Do I just run the whole ADF binary through a CRC32 routine?

The budget sound chip inside the affordable Super Nintendo (released late 1990) is superior to Paula in most areas, despite its small 64K RAM space. Still silly?

Bundled fastmem and an improved Paula would be very welcome for an Amiga released in '92. It's almost silly it didn't have any of that.

The X-Fade implementation is very crude in ProTracker. You can't use it to create perfect loops (unlike the better X-Fade in Fasttracker II, for instance).

Yup. A 486 is guaranteed to have fast internal L1 cache, while a 386 would have external L1 cache at best (usually no cache at all).
Writing code to be optimal for cache-based systems is a thing.

I decided to go with the slow method, like said. So max 128kB allocation (for a 128kB sample). It's faster on A1200 and expanded Amigas anyway.

Possibly, but it could also be because of a bad import, which is especially common for 15-sample .MOD formats (Ultimate SoundTracker). It's a nightmare to import these correctly in a universal player.
