-GOAL:
-live-program an emulator in assembly
-
-- a program is a graph that is flattened into a set of bytestreams.
-- first step: make the damn graph.
-
-APPROACH:
-- program is split into "ROM" and "RAM" - ROM is code that generally doesn't change while the program is running, RAM is program data
-- a program is assembled from snippets that refer to other snippets by name
-- a code snippet can be marked as a "loop point", a safe spot to pause and replace a running program's code
-  - this is also be a good spot to take snapshots of "RAM" which we could roll back to
-  - this assumes an empty stack + no code references in RAM - perhaps a special typed variable is needed for snippet pointers?
-- for now, we will depend on gsplus' socket-based remote debugging capabilities to poke the program into emulated memory
-
-WHAT IS A SNIPPET
-- label + block
-- block = bytestring, labels (offset into instruction list), fixups (label references)
-- can concatenate blocks; snippets are stored "loose" - accessed by absolute JMP or JSR
-- other compositional ideas:
-  - "scopes" - keep labels "alive" only for a short period, for autogenerated loops, if statements, etc
-    - could also just gensym
-
-(lda 13) ; immediate
-(lda (addr #x2000)) ; absolute
-(lda (addr #x20)) ; zero-page
-(lda (off-x (addr #x20))) ; zp,x
-(lda (off-y (addr #x20))) ; zp,y
-(lda (off-x@ (addr #x20))) ; (zp,x)
-(lda (@off-y (addr #x20))) ; (zp),y
-(lda (off-x (addr #x2000))) ; abs,x
-(lda (off-y (addr #x2000))) ; abs,y
-
-label = lazy address
-maybe treat zero-page and absolute as different types? we will always plan what goes into zero-page. zp has addressing modes abs doesn't.
-
-each opcode is a function that returns a block, usually 0-3 bytes with optionally associated labels + fixups
-(fixup is a tuple: local offset, label reference, and whether we're expecting an absolute, zero-page, or relative address)
+Neut Tower runtime model:
+- before moving, see if an object exists at that location - if so, send it a message
+- otherwise, see if the space is "empty" from the current player's perspective - if so, move them there
+- lookup table for tiles? rol rol rol to get index, 8 bits of possible data
+- objects are kept in two parallel arrays, rather than a linked list
