AFTER CLONING THE REPO, CHECK OUT THE include/config.h FILE BEFORE ANYTHING ELSE! IT THERE'S A LOT OF STUFF IN THIS REPO THAT CAN BE TOGGLED THERE.

This repo needs gcc in order to be able to build it. To install it, run sudo apt install gcc-mips-linux-gnu

This is a fork of the ultrasm64 repo by CrashOveride which includes the following commonly used patches (patches marked with * are toggleable in config.h):

• slope fix
• exposed ceilings fix
• No false ledgegrabs fix *
• Jump kick fix *
• 46 degree wallkicks *
• Possibility of disabling BLJs *
• Instant Input patch by Wiseguy (Removes all input lag caused by good emulators and plugins)
• pole fix
• Hanging fix (mario can grab hangable ceilings from any state, instead of only jump or double jump) *
• Mario head skip *
• Peach letter cutscene skip *
• Castle music fix (Fixes the castle music sometimes triggering after getting a dialog) *
• Ability to easily change the warp that EXIT COURSE takes you to via config.h, or disable it entirely
• Exit course while moving *
• Toggle to disable fall damage and the fall damage sound *
• Ability to configure whether there's a 100 coin star at all and how many coins are required to spawn it *
• Non-stop stars *
• better extended boundaries by anonymous_moose
• water surface type patch by thecozies
• platform displacement 2 by arthur *
• FPS counter (use the function print_fps(x,y) anywhere that runs code every frame)
• Automatic console/emulator detection. If emulator is detected, LODs are disabled. *
• Rounded corners by Frame, merged by Cheezepin
• Widescreen (16:9) support toggleable by pressing L in the pause menu. *
• Removed course-specific camera processing *
• Increased maximum pole lenght (The game will read bparam1 and bparam2 together as a single value, so you can have a very long pole) *
• bparam4 fix (the game no longer uses bparam4 to check if an object is mario and therefore you can safely use it)
• Instant warp offset fix (makes the instant warp offset work even when warping to a different area) *
• Global star IDs (disabled by default, toggleable in config.h). This allows you to create an open world (MVC-style) hack. *
• Included actors/group0.c in behavior_data.c
• 16 bit model IDs by someone2639. This means you can have up to 65536 models (lol)
• s2dex engine by someone2639! To use it, compile with make TEXT_ENGINE=s2dex_text_engine or just set TEXT_ENGINE to s2dex_text_engine in the makefile.
• haveyourcake, also known as cake screen fix. Made by Wiseguy and ported/PR'd by Cheezepin
• Tree particle fix (Whether a tree uses snow particles or not is decided via the model IDs instead of the course number)
• Removed the ifdef hell in file_select.c and ingame_menu.c
• Added blake's custom function for object model stuff: obj_set_model and obj_has_model
• Coordinate overflow fix by falcobuster. Your levels will render correctly on console and LLE emulators even when using 2x or 4x bounds, while not hurting anything on HLE plugins. This is automatic now, you don't have to set WORLD_SCALE manually.
• The "far" variable has been turned into a u16, which allows you to increase the farclip (the maximum distance at which geometry gets rendered). However, when increasing the farclip, make sure to increase the nearclip by the same ratio, or the rendering will break on console and LLE plugins.

It also uncringes the way that apply_patch.sh works, and removes the black border.

• 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.
• Newer compression options are supported.
• UNFLoader (flashcart USB library) is supported, allowing for debugging on EverDrive/64Drive.
• It has been patched with someone2639's shiftable segments patch
• Getting HVQM FMV support to work with the game is WIP.

The repository supports UNFLoader for debugging.

To build with UNF, run make with UNF=1.

Further instructions can be found at the official repository

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.

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.

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.

The repo also supports gziping 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, then make and make install it.

Then run make for sm64 with GZIPVER=libdef in addition to COMPRESS=gzip

The repo also supports RNC (Rob Northen Compression). RNC has two methods.

Method 1 is designed to compress as small as possible, while method 2 is designed so that decompression is as fast as possible.

Both methods are fast. Method 1 has better compression than 2, so I suggest using method 1 if using RNC.

To switch to RNC, run make with either COMPRESS=rnc1 or COMPRESS=rnc2, depending on preferred method.

The repo also supports building a ROM with no compression.

This is not recommended as it increases ROM size significantly, with little point other than load times decreased to almost nothing.

To switch to no compression, run make with the COMPRESS=uncomp argument.

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.
