+# SplatooD: A Splatoon demake for NES
+
+![screenshot](http://i.imgur.com/jGOvsaF.png)
+
+## Controls
+
+D-pad to move, A to flick roller, START to pause. Menus accept D-pad to move cursor and START to select an item.
+
+## Building
+
+Install [cc65](ftp://ftp.musoftware.de/pub/uz/cc65/cc65-sources-2.13.3.tar.bz2) v2.13.3 or thereabouts and then run `make`.
+
+Assets were created in NESST and Famitracker.
+
+### Updating Strings
+
+All strings in SplatooD are formatted as EBCDIC with an offset. Use the Python script in `util/ebcdic.py` to convert ASCII to appropriate arrays.
+
+### Updating Nametable Headers
+
+There is a tool to convert binary nametables into C headers in `util/bin-to-h.py`.
+
+## Cartridge Details
+
+We target an NROM256 cartridge with two 16kB PRG ROMs and one 8kB CHR ROM.
