 Game:
-* Ending screen
-* Intro sequence (how to show earthquake?)
-
-
-FLOPPY DISK IDEAS:
-* I am not going to write my own DOS
-* I will use ProDOS - BOOTI-compatible, modern
-* ProDOS 2.4.2 - https://prodos8.com/
-* Generate file(s) to be injected into a blank bootable ProDOS disk image
-
-thinking:
-neut.tower contains all code / data
-loader.system contains a small program that maps offsets of 512-byte blocks to memory addresses
-- is loaded to 0x2000 & will be wiped by gfx? No, PRODOS is loaded at $2000 and moved
-- no, XXX.SYSTEM is loaded to 0x2000 as well
-- Alternately, we could write one program that batch-loads the whole game into $2000 and moves it to where it belongs?
-- How big is the game with all levels? Could we load the whole thing into consecutive memory starting at $4000?
-  - (I don't think this would work on 32kb tape-loaded machines...)
-- With ProDOS I can assume 64kb
-prodos claims:
-$bf00-$ffff - ProDOS
-$9600-$bf00 - BASIC.SYSTEM - don't care?
-$0100-$0800 - "other use or reserved"
-$3A-$3F - used by disk routines, unsafe
-$40-$4F - used by ProDOS but preserved, safe to use
-
-system bitmap: marks pages of memory as "not valid to allocate a file buffer"
-- loader will have to protect memory that it will be moving game code to?
-
-https://prodos8.com/docs/techref/calls-to-the-mli/
-the existence of SET_BUF should mean we can load directly to the memory
-we care about? orr I guess 512 bytes is housekeeping stuff (index block)
-
-16kb version - $0000-$4000 - no we need at least 32kb
-there's basically only 5kb of code space for an hgr game?
-$0000-$03ff 0kb-1kb - zp, stack, input buffer, DOS
-$0400-$07ff 1kb-2kb - text page 1
-$0800-$0bff 2kb-3kb - text page 2
-$0c00-$1fff 3kb-8kb - free space
-$2000-$4000 8kb-16kb - hgr gfx page 1
+* cheat codes
+* save/load
 
 tooling ideas:
 * REPLy buffer (Polywell?)
