hydr8gon/sm64

A port of Super Mario 64 for the DSi

sm64's Issues

Linux: No such file or directory: 'baserom.us.z64'

i do have baserom.us.z64 at /sm64, yet i get this error

Please add an icon and name to it.

The game works fine already. I'd just like it if you added an icon and title to it.
I need it for my personal SM3DASDS.
and yes, i renamed the file to 1996.nds

I have Docker but it deos not run

This is the error:
error during connect: This error may indicate that the docker daemon is not running.: Post "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&shmsize=0&t=sm64dsi&target=&ulimits=null&version=1": open //./pipe/docker_engine: The system cannot find the file specified.

Sound completely stops working when 4 stars are collected (UTL-001 hardware), performance issues

Collected these stars:
-Big Bob-omb on the Summit
-Secret slide <21 second star
-Secret slide normal star
-Plunder in the Sunken Ship
And the game audio stops working.
Using an actual Nintendo DSi (XL UTL-001, unsure of the revision if there is any)
Game loaded onto a 16GB SD card, started with unlaunch

As for performance issues, the game would lag at areas in more intensive areas. (high poly counts?) Replacing -g with -O2 doesn't seem to make a noticeable difference either. However, at some point I changed the screen resolution to 256x192 in config.h and that... didn't seem to work out too well. The game was aligned to the bottom left corner of the screen and the rest of it was just black. Perhaps there's another area to change, but i don't know. Plus, you would need to change the alignment of all the objects (HUD, letters/numbers, text, etc; 3d models look fine) printed on screen to fit the resolution.

Thanks in advance for reading through this.

Port will not start from TWiLightMenu++ on real DSi Hardware

Hello,

Although I have successfully compiled this port, I was unable to start this port on my actual Nintendo DSi using TWiLightMenu++. It crashes to a black screen.

Here are some of my TWiLightMenu++ Settings for reference:

Run in: DSi Mode
ARM9 CPU Speed: 133 MHz (TWL)
VRAM Boost: On
S1SD: Use nds-bootstrap Yes
Sound/Mic Frequency: 32.73 kHz
DSiWare Booter: Unlaunch

I do not understand how to do any of this

Please help I don't understand how to do this I downloaded the rom and the sm64 nds but I don't know how to get the game since I don't know if you use docker to get the game can someone explain step by step please

Game crashes when trying to save in the basement

whenever i try to save in the basement the game crashes.

wont build

I was following the instructions fully but when I opened the build batch file it says

"error during connect: This error may indicate that the docker daemon is not running.: Post "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&shmsize=0&t=sm64dsi&target=&ulimits=null&version=1": open //./pipe/docker_engine: The system cannot find the file specified.

any fixes?

Hardware accelerated floating point functions

Kuratius@ace0e20

I tried implementing hardware accelerated fdiv and sqrtf functions, I also tried writing an fmul implementation that should be somewhat faster than the default.
There's also a rounding implementation that avoids float adds:
Kuratius@515fc97

Note that the fdiv and sqrtf use the hardware divider and square root unit while doing other stuff for the float handling instead of blocking; that may mean that handling of NaNs and other invalid values could be added without changing the performance of these functions.

Also note that they do not handle invalid values such as NaNs, overflows, underflows, and infs in a proper way.
I think most of the compiler option reshuffling isn't necessary, only the --use-blx --wrap and -u flags are a actually necessary to get it to use these functions instead of GCC's default soft float implementation.

I noticed some minor graphical issues (like 1 frame every few seconds that looks wrong) when using these, but it's hard to tell what causes that, if NaN handling is required or if something else is going wrong. Probably don't add these to the project by default unless that gets tested further.
This also should be benchmarked in more detail.

I'm opening this issue so that the discussion about this isn't hidden away in the discord.

Three sound issues

1. Pausing the game causes the played instrument to linger on.
2. After beating Bowser in the final level and transitioning to the final cutscene, the sound stops working.
3. Red coin sound does not play, and it's just normal coin sounds.

Check if sin/cos approximation via integers has sufficient accuracy and speed

It's possibly to compute a good approximation to the cosine of a number using a single float multiplication and 1 integer multiplication.

The implementation from this video for example
https://www.youtube.com/watch?v=hffgNRfL1XY
(see e.g. 8:02 )

can be modified to use only integers except for the very last step.
Example:

#define SECOND_ORDER_COEFFICIENT 0.0000000010911122665310369f
uint32 a=3667592205

float b=1.f/a ( can be evaluated at compile time)
sint32 c= (sint32) (SECOND_ORDER_COEFFICIENT*a) (also compile time)

uint32 x=16382 (0 is 0 angle and 16382 is pi/4 ), values lower than -pi/4 or greater than pi/4 need to be done with symmetry transforms or the squareroot operation.


 float result=b * (a-c*x*x)

the compiler optimizes this a bit to turn 2 integer multiplies +1 float into 1 integer multiplications and 1 float multiplication.
There are other possible values for a that can be chosen, potentially with less error than the one I used for this example, especially if the range of x is changed. The float multiply could also be replaced with a hardware divide if the angle doesnt have to be a float.

The current implementation seems to use a 8th order polynomial with doubles.

sm64/lib/src/math/cosf.c

Line 36 in a4b5e94

float cosf(float x)

I'm also a bit confused as to why p[0] seems to be unused here.

I’m having a problem with whole baserom.us.z64 thing.

So I have a majority of the things used for the compile prepared. I have a US rom version of the super Mario 64. I have docker installed and I have the sm64-nds file installed as well. I extracted it and I put the US version of super Mario 64 into the sm64-nds file and renamed it “baserom.us.z64”. I ran the build-docker.bat file and it gave me an error. The error said: “error during connect: This error may indicate that the docker daemon is not running.: Post "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&shmsize=0&t=sm64dsi&target=&ulimits=null&version=1": open //./pipe/docker_engine: The system cannot find the file specified.

Changing the control layout

I was wondering if you could please change the control layout? It would make more sense if you could change Y as C left and X as C right and use the touch screen for C up and C down.

The writings are difficult to read

The super mario 64 font is quite peculiar and reduced on a small screen with few pixels is quite difficult to read. How hard would it be to change the font?

Hardware sqrt helper functions

In #32 it was shown that you can use the hardware sqrt operation to replace a software one in nds_renderer.c. The default libnds sqrt function has extra checks that are unnecessary and does not support async computation. Libnds' sqrt does a check to make sure the hardware divider is not busy before sending the value, it only takes ~30 main bus cycles according to my testing, this means that unless you have two hardware divides back to back, there is no reason to check this value twice. Blocksds uses a simpler approach by having async functions for sending values to the hardware math coprocessor, this means we can use the cpu while waiting for the hardware math to complete. With testing I have found that replacing the sqrt call referenced in #32 with an async send, then check if (s > 0) and then wait for the hardware to finish the operation. In testing this saves 10-20 microseconds per frame.

// Normalize the result
int s = (lights[i].nx * lights[i].nx + lights[i].ny * lights[i].ny + lights[i].nz * lights[i].nz) >> 8;

// Send squareroot value to hardware before comparing (s > 0), this saves 10-20 microseconds
// Devkitpro's libnds does not have helper functions for async hardware math. This should be 
// put into a helper function.
REG_SQRTCNT = SQRT_64;
REG_SQRT_PARAM = (s64)s << 16;
if (s > 0) {
    while (REG_SQRTCNT & SQRT_BUSY);
    s = REG_SQRT_RESULT;
    lights[i].nx = (lights[i].nx << 16) / s;
    lights[i].ny = (lights[i].ny << 16) / s;
    lights[i].nz = (lights[i].nz << 16) / s;
}

If we do not switch to Blocksds, I propose we at least have these functions in a header file to have better operability with the hardware. The question I have is, where should this function go, so that it can be used by more than just nds_renderer.c if it comes to be useful later on? Should this be a function or a preprocessor define: #define sqrt_asynch(x) ...?

check if fixed point square root in renderer can be replaced with hardware squareroot instruction

Windows: baserom.us.z64 not found in the directory

I haven't done anything like this so I'm quite confused how to do this and I'm not even sure if I know what a directory is so help needed

Performance Optimization: Using TCM and Wram

The current code does not use any of the TCM. This means that the instruction cache and data cache are overwritten more often and leads to more reads to main ram. This is a fairly free performance improvement that putting the most commonly run functions into the ITCM, and putting data that is used only by the arm9 cpu into the DTCM would improve some performance.

I have experimented with this and it is not a night/day improvement for filling the ITCM with commonly run functions. Likely due to cache coherency, so there should be a method of finding the best functions based on how commonly they are run, and if the function is run before the instruction cache is overwritten.

The DSihas 800KiB of wram putting data and functions there would mean faster read times and less stalling execution due to the arm7 reading audio data on the main bus. The comparison of read speeds from the wram and main ram can be seen here. The current arm9 instructions are about 800KiB in arm mode, and if we use thumb mode it is around 600KiB, which could fit into the wram. There is a basic implementation of wram in Blocksds.

Font is unreadable

Can’t read anything. Font is corrupted.
Maybe you can fix it?

Could someone please run me through a step by step process on compiling? please?

All I want is a process on how to compile this port so I can try it out for myself. I'm pretty amateur when it comes to compiling so please help!

Add 3DS port to this project as another option

I discovered there also exists a 3DS port https://github.com/sm64-port/sm64_3ds. It would be great if these were consolidated to a single repository which users can choose which ROM to compile (or compile both). More importantly it appears that fork is abandoned now while this fork is still being actively maintained. As they are very similar to each other in nature, I think it would make sense to consolidate.

Some of the rooms are buggy

I noticed a problem loading some of the big boo's haunt rooms. The level started off perfectly, but when you enter the third room from the left on the ground floor the textures are buggy and move fast in a messy way. The same thing happens in the third and fourth rooms upstairs. Looking at the crazy camera angles in those rooms I can speculate that the camera on the dsi has been adapted differently from the n64 version and somehow protrudes out of the walls of those rooms. I haven't played all levels of the game so I don't know if this happens in other cases as well. Is there a way to fix this?

reset button combo

the game relies on the presence of a reset button for things such as loading a different file (without bringing up the save dialog) and exiting the ending screen

The game lags a lot when there are many entities in the frame

That's all. I know that perfect emulation is difficult because of the hardware but I wanted to point out this problem. If there is no way to fix it, I will close the issue.

Performance Optimization: Using Thumb Mode

Currently all the code is stored in main ram, and the arm9 core stalls when the arm7 core is reading from main ram. If the code was compiled in Thumb mode (and possibly with size optimizations, -Os/-Oz) it could require fewer ram accesses to execute the same code, and therefore reduce the performance hit from the low main ram and the audio. From testing I the code size seems to shrink to about 60% of the original size using thumb and -Os. I did not notice a significant change in performance, but did not perform the most detailed of tests, importantly this did not slow down the program at all. This would be a simple change to the Makefile.
