If this is likely to become a popular game (paging from compressed
binaries), would it be useful to build a special "binary gzipper" that
split and separately compressed independent 4k pages? I believe that
the V.42 compression in modems forces blocking at 256-byte boundaries,
to minimise the amount that needs to be re-transmitted on errors, and
that still manages reasonable error rates. You would need to build a
table of pointers to each of the blocks to avoid scanning the whole
thing, but there could be some gain. Is there an obvious reason for
this not to work?
