 - Getting HVQM FMV support to work with the game is in progress.
 - Getting UNFLoader (flashcart USB library) to work with the game is in progress.
 
+## Multi-Save support
+
+The repository supports SRAM in addition to EEPROM. The standard save data functions are #ifdef'd to accommedate this.
+
+To build with SRAM support, run make with ``SAVETYPE=sram``.
+
+I may attempt FlashRAM in the future.
+
+## Multi-Console support
+
+The repository supports targeting the iQue Player in addition to the N64. The iQue libultra is ***NOT*** compatible with N64 in many ways, so it is currently NOT possible to have one build for both consoles.
+
+To target iQue, run make with the ``CONSOLE=BB`` argument.
+
+## Compression
+
+The repository supports using DEFLATE compression instead of Nintendo's Yay0. This boasts a better compression ratio, but at a slight cost to load times.
+
+On average I'd estimate that the bottleneck on decompression is about 1-2 seconds.
+
+To switch to gzip, run make with the ``COMPRESS=gzip`` argument.
+
+Additionally, the repo also supports compressing with ``libdeflate-gzip``. This compresses at a slightly better ratio than standard ``gzip``, with no real downside from a decompression standpoint.
+
+To use ``libdeflate-gzip``, first clone the [repo](https://github.com/ebiggers/libdeflate), then make and make install it.
+
+Then run make for sm64 with ``GZIPVER=libdef`` in addition to ``COMPRESS=gzip``
+
+This argument makes the makefile use ``libdeflate`` with it's highest compression setting, ``-12``.
