Hi there!

Is it true that indexed-indirect addressing as LDA ($nn),Y is limited
to zero-page addressing?  Seems that way, with DASM throwing an error
if $nn > $FF.

Sad but true, yes.

Of course, this isn't usually an issue for 2600 programming
- I only bumped into it when coding for Superchip RAM - but it seems
like a pretty severe limitation for the 6502 in other environments?

I just checked, more than 1/4 of the C64 zero page is reserved for pointers to various 16-Bit adresses.
