Getting the best N64 experience on a Pi 4

@roslof FBE is definitely set to true by default. it is needed for so many games to function correctly.

Thank you @dankcushions
Perfect. I'll make the note in the list. -

Overclocking ISP and h264 frequency is unnecessary and confusing to newbies. It won't hurt anything but these are used for the image sensor pipeline (aka camera) and for video decoding. They aren't used at all in emulation.
Good idea. I edited my post and removed the two lines.
Second, many games will be broken with framebuffer emulation turned off. I don't recommend turning it off (it's on by default for a reason). The performance boost isn't worth it if the game doesn't function properly.
From testing about 70 games, the number that require Frame Buffer Emulation seems to be very low. Seems better as an override in this case. Do you know if it affects PAL games more than NTSC? My optimized set is NTSC, and only PAL is used if there is no NTSC equivalent.
Threaded rendering should be left on, I can't think of a case where turning it off would be beneficial (except maybe input latency).
This may again be because I'm primarily using a custom NTSC ROMset. Performance seems to be a factor here. You have me thinking that I should retest the games for those emulators with the option on and see if the FPS Delta is significant.
@quicksilver I know you've done your homework and have helped in several threads. Appreciate your help here.

@roslof yes i'm 100% sure fb emulation causes alignment issues on pal games, Cause i logged an issue at the gliden64 repository and this was the answer of the developer:
N64 has Video Interface (VI) subsystem, which maps digital image to TV screen. VI controls, how the image will be placed on screen. For example, your MK64 shots. I'm sure it is PAL version of the game. It has black bars on top and bottom because PAL has more horizontal lines than NTSC. VI adds vertical offset when it maps image to screen. Emulation of VI is part of FB emulation.In other words if you switch off fb emulation you miss an essential capability to display the video correctly for pal.
Details can be found here
In my experience it works fine on ntsc.

@akamming thanks again. Will make the adjustments.

Yoshi's Story on Rice is just too glitchy for me, I'm using lr-mupen64plus even if that is slightly jumpy at scrolling sometimes. I can't cope with my eggs being black squares.
I changed the recommendation to lr-mupen64plus but added notes about the Rice option. Thank you!
WaveRace 64 - if I use lr-mupen64plus, the bottom of my screen gets cut off, there is a black bar at the bottom. I've been using GLideN64-highres, which isn't full-screen but does seem to run fine.
Changed recommendation to GLideN64-highres. Thanks here too,
on Killer Instinct Gold, as @quicksilver mentioned above - if you use mupen64plus-gliden64 and let the game run for a fight or two, the game then begins to run fine and will be okay for the rest of the session.
Changed to GLideN64 and credited accordingly.
if anyone wants to play Mystical Ninja Starring Goeman, then mupen64plus-gles2rice is the emulator to use, and make sure you use the US ROM, as there is something awry with the European version.
Added this test and credited. Thank you!
Getting lots of good advice for the group.

...Maybe this can help Pi4B owners get rolling more quickly, as it takes a long time to find recommended emulators for ~400 games.
I run perfect dark in 16:9 480x360 in Lr-Mupen64plus-next with very similar overclock settings (see my sig). Several games will run in Lr-Mupen64Plus-next at 320x240 with MSAA set to 2 with very little performance drop.

What is MSAA? I'm not familiar with it. I don't suppose it fixes the Spycam parts of Perfect Dark, those are a bit janky on my playthroughs so far.
I guess I'll have a play around.

@AdamBeGood (multi sample) Anti aliasing. SotE looks really good with it.
-
@AdamBeGood the camspy should work just fine using mupen64plus-gliden64 with default settings on the pi 4. It won't work at all on previous pi models.
-
@quicksilver Yep, you are right. I am not sure what emulator I was using before then...
That part even seems okay on highres, but there is a bit of slowdown generally (Villa level isn't great). Shame, as it seems quite close to being able to run fine and it looks better than the normal lr-mupen64plus.

change screen update setting to 7 and it will get rid of the strange "jitter" issue that gles2rice has on the pi 4
Awesome ! it works .. thanks very much :)
-
@roslof First of all : thank you. This list was much needed.
But, for some reason, even if I have very similar settings (OC : arm:2000, core:550, v3b:800, skipframe=true, framebuffer=false, screen update=7), but I do not get the same results... :(
For example : when playing Excitebike 64 with Rice, not only is the screen window super small, but the game still stutters a lot. For Super Smash Brothers, Gliden make it fast, but the sounds is super crackling (at each sounds peaks)...
Anything anyone could see that I would be missing?
Any help or references will be appreciated. I am new to Retropie with Pi 4 and pretty discouraged with N64 emulation (my favorite console from my childhood)...
-
@Nakynaw would you create a paste.bin of your settings from:
/opt/retropie/configs/n64/mupen64plus.cfg
/opt/retropie/configs/n64/emulators.cfgI'll compare yours with mine and share the delta with you.
-
@roslof being a NOOB, I am surprised that I succeeded in setting up SSH, copying the files and creating a paste.bin, all for the first time. I hope I did it correctly.
Thank you a lot for your kind offer!
Also, as an update : since the editing of the Rice part for the mupen config, excitebike is almost ok, but, of course, now Smash Brothers is much worst and does not just crackle, it is super slow and stuttery.

https://pastebin.com/NTRRdJz2
https://pastebin.com/xrwv0Ah7I believe Smash Brothers works best with mupen64plus-GLideN64-highres. Try that instead (just for that ROM).
Our emulators.cfg match perfectly.
Your mupen64plus.cfg file looks janky, with a big gap after column 80. Probably won't hurt anything, since it only seems to cut through the comments, but still -weird. :)
Deltas in mupen64plus.cfg [Video-Rice] section:
FrameBufferWriteBackControl = 1 (mine is 0)
InN64Resolution = False (mine is True)
SkipFrame = True (mine is False)Hope this helps.

One thing I’ve noticed on N64 games on Retropie is that games like Goldeneye and Excitebike 64 run extremely well in-game, but have badly stuttering sound in the menus and title screens. Why is that? I would have thought that the actual game bit of Goldeneye was more demanding than the level select menu.
-
@roslof thx!
I will keep testing, and trying your suggestions. But I think I should go back to the default and up to date "mupen64plus.cfg" first. I kept trying stuff since many games became way worst with mupen64plus-gliden64 after some changes I made.
The way to reset it is to erase the file and reinstall the emulator right?
If so, I have to figure out how to erase it, if anyone can spare a minute to guide me, I would be very thankful!

mv /opt/retropie/configs/n64/mupen64plus.cfg /opt/retropie/configs/n64/mupen64plus.cfg.bakbut if you really want to nuke the file, do this:
rm /opt/retropie/configs/n64/mupen64plus.cfgI'm not sure if the file will automatically regenerate, but chances are yes -- you may need to reinstall.

I started up an N64 compatibility list, specifically for Pi4B and all of the various supported RetroPie emulators and added a section for emulator default overrides.
The first pass of the RetroPie Nintendo 64 Pi 4 Compatibility List is complete. Even though this is a highly optimized list (primarily NTSC and no prototypes) this took a solid week. Also, I'm human, so there are bound to be typos or missed optimizations. Feel free to share suggestions and opinions. The Compatibility List now accepts comments.
Not sure if the creators of these excellent emulators are working together or not but the list may be helpful in solving a lot of issues specific to the Pi4. Newer emulators have been created and are apparently more compatible on other devices. Not sure what additional love the Pi devices will get.
The vast majority of games are working with RetroPie, albeit some better than others. All observations are noted in the Obervations & Notes section of the Compatibility List.
Will be looking forward to playing with newer optimizations (Raspberry Pi graphic driver updates, 64-bit support, newer emulators and existing emulator enhancements) but for now, at this date in time, this is a pretty good read on where things truly are.
TRENDS:
Oddly, lr-mupen64plus typically outperformed lr-mupen64plus-Next with optimized settings. Not always, but more often than not. In the list, you'll note I recommend "plus" more often than "next". This isn't a personal bias, rather from observation on what provided a better gameplay experience.
For NTSC, the "lr-Next" build struggles with full-screen display that usually require Framebuffer Emulation set to true, which absolutely tanks emulation speed. The older "lr-plus" emulator handles most of these full screen issues without the need to enable Framebuffer Emulation. Not sure why. But this is a major reason why so many games play better with lr-plus than lr-next.
UI behavior seems to be more of an issue with Pi4 emulation than gameplay. For some games, it feels like the emulator will freeze/crash, but if you muscle through... you can usually reach some excellent gameplay. In several cases UI can get so bad that you can't [easily] get to gameplay easily or even exit the emulator properly.
Most Imagineer/Genki games need to change the CPU Core or weird things happen. Not typical to change this for any other game. For any of the bad-behaving games listed below, I tried different CPU Core options, but none would fix the problem(s).
It was remarkable how many times a game played poorly on 3-4 emulators, then worked AMAZING with exactly one. There is no single "best" emulator here. Without the complete collection of emulators, less games would be playable.
Regarding lr-parallel-n64. Such a disappointment on the Pi4B -- but also my hero... in exactly two (2) cases... It actually plays NFL Quarterback Club 99 where other emulators can't even boot it. There is no better, current emulator to play GoldenEye 007. Would LOVE to know why lr-parallel otherwise crashes for 90-95% of the games. It's experimental, of course, but it could be killer of it would just remain stable.
Lastly, here are the games that I could not get to run well with any emulator:
NOT WORKING/ NOT PLAYABLE/MAJOR ISSUES:
Disney's Donald Duck - Goin' Quackers
(Game seems to play well, until you learn that you cannot collect stars with any existing Pi emulator)Glover
(Will not boot with any existing Pi4B emulator)Hey You, Pikachu!
(Cannot play, since Microphone is necessary peripheral)Knife Edge
(Game throttle is not working, so it really moves fast... Impossible to play/target)
Note: I tried playing with Count Per Op (from 0 to 5) but could not get solid gameplay.Masters '98
(Swing meter rendering issue extremely slow, or starts slow the suddenly moves fast.)NBA Hangtime
Game effectively 'hangs' around 0.5 FPS starting at tip-off.
EDIT here from 2020/09/14. Thank you @NakynawNBA Showtime
(Animations are not throttled, so animations/gameplay speed is terribly fast when performance is good)Quake II
(Visual particle effects slow game to an unplayable speed)Top Gear Hyper-Bike
(Actually playable, but the ground texture is not properly mapped, so can't "see" the course.)Vigilante 8
(Unstable. Will eventually crash/freeze. Broken interface and poor performance)Vigilante 8: 2nd Offense
(Unstable. Will eventually crash/freeze. Broken interface and poor performance)Waialae Country Club
(Same engine as Masters '98. Swing meter rendering issue extremely slow, or starts slow the suddenly moves fast.)All other games are playable with the emulators noted and with the options set.
Hope this is helpful. It helped me complete a pretty solid, clean collection of games.
