# UltraSM64
- This repo contains a full decompilation of Super Mario 64 (J), (U), (E), and (SH).
- Naming and documentation of the source code and data structures are in progress.
- It has been edited to allow for the usage of the final "N64 OS" library, version ``2.0L``
- Shindou Rumble Pak code is on for all regions.
- Targeting the iQue Player is supported.
- Saving to 32kbyte/256kbit SRAM is supported.
- Using gzip DEFLATE compression is supported.
- It has been patched with someone2639's shiftable segments patch
- 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``.
## FAQ
Q: Why in the hell are you bundling your own build of ``ld``?
A: Newer binutils (Like the one bundled with Ubuntu, 2.34) break linking with libultra builds due to local asm symbols.
This puts me at a crossroads of either touching leaked code and requiring GCC, or just using an older linker that works just fine.
I went with the latter.
Thanks to "someone2639" for this hacky-ass idea
Q: Will this allow me to use FlashRAM/Transfer Pak/microcode swapping/Other Cool N64 Features?
A: Theoretically, all yes.
