Getting the best N64 experience on a Pi 4
-
@agtrigormortis It was possible to modify the RAM speed on a Pi3. Is this still possible on a Pi4? Has anyone experimented with this (up or down) and got any noticeable results?
-
@george-spiggott To be honest I'm not sure, even if you can though there will be thermal limits like with OCing the other hardware and in the end we will still be restricted by cooling and voltage.
Because of the size of my case I cannot exactly install an Ice Tower cooler on mine, my Digitalkey case is too small for that, but it did allow for the aluminium alloy Geekworm heatsink with active cooling. The intention is to install the case onto a Vesa mount on the back of a monitor.
When I get around to OCing it I'd probably cap out at about 1.8ghz, it just depends on what the heavy load temps are.
-
@george-spiggott it kind of describes many things that are involved in shunting data around the system until it results in putting pixels on the screen. the pi series have a shared memory architecture and hence not the dedicated highspeed graphics ram you might find on a traditional GPU. that said, i am not sure the upgrade from LPDDR2 (pi1-3, i think) to LPDDR4 (pi4) made a massive difference to the situation, so it could be more to do with the system bus, CPU cache, or something else. the GPU drivers may be inefficient. all i know if you can easily bring the pi4 to its needs with certain 2d emulator and a shaders, just because several elements are fighting for limited bandwidth.
but in general terms, the rpi series are general purpose, cheap computers. they're not really designed for what we're trying to do with them. personally i think overclocking (on pi4) has generally little benefit for things like n64, and that is born out in benchmarks (that very few people seem to be interested in doing).
-
@dankcushions Regardless, by the time the Pi 5 comes out if there will be one I think it will be enough for bare minimum near flawless N64 and PS1 emulation, provided the software was programmed to make proper use of it.
But then we're up against the next big hurdle, Xbox 360 and PS3 emulation.
How many Pi generations would it take to get this done properly? especially running games like Forza 2, PGR3, Halo 3 and Kingdom Hearts 1.5 and 2.5 remixes? my prediction is Pi 8 or 9, so it's a long wait. -
@agtrigormortis I'd say the next big hurdles are PS2, Gamecube and the original XBox.
Not to mention the Saturn which is still very much hit and miss. -
@zering Sega Saturn had some cool looking games too like Sega Rally and even had its own port of Virtua Racing. Yeah I found out about the problems with Saturn emulation a while back, I do want to get some official disks to rip their ISO's to my Pi 4 to try them out but looks like I have to start with Sonic Adventure and Crazy Taxi Dreamcast, which do emulate surprisingly well on the Pi 4.
-
@agtrigormortis You want to buy Saturn disks? I'm assuming you have kidneys you no longer need? ^^
Dreamcast emulation on the Pi 4 us excellent, I'm running most games in native resolution with no frameskip on lr-flycast. Only Giga Wing and Mars Matrix have been slow but they run better on MAME anyway. Sadly there's still no way to run those finicky Windows CE games.
I'd recommend you try N64 Pi 4 emulation for yourself, you might be surprised. I upgraded from the Pi 3 because mine was dying, and I only expected incremental improvements. Then next thing I knew I was playing through Conker's Bad Fur day with not a hint of slowdown or graphical issues. (It was unplayable on Pi 3) -
@zering Naw lol I found out about the emulation problems from some Youtubers, Sega Saturn is clearly off the cards there, but I am willing to try the Dreamcast ones, just not the pirated versions because I don't want to risk financial difficulty through seeded torrents. I'll need to try to get them from Ebay if I can.
the interesting thing about the Pi 4 is some PC games will work on it too, like Quake 3 Arena, I don't know how exactly but for some reason people managed to get that game to work on the Pi 4, along with some others. Probably related to the Windows 98 emulation through Dosbox or something. ^^

@agtrigormortis Quake 3 runs through a source port, and as far as I know it ran fine on the Pi 3.
So you're not actually speaking from experience? What systems did you try on the Pi 4? -
@zering None yet, I've only just pieced mine together, I tested RetroPie on it which seems to run fine.
But when I get around to testing it I will find out what works first hand and what doesn't, instead of just taking information from people I don't know IRL.
Oh yeah now that I think about it I think the guy in the Youtube video said it worked on the Pi 3 with the Vulkan drivers, you're right it is a source port and he said we have to wait for Vulkan for the Pi 4.
My apologies for the misinformation, I got confused there. lol
Quake 3 Arena did work fine on the Pi 3 at 100+fps with occasional dips to 60 IIRC.
So when Vulkan comes to Pi4 Quake 3 should remain at 100+ even with Lightmap and trillinear settings in OpenGL. -
@agtrigormortis As always with the Pi - tinker. You'd be amazed with the leaps in performance you can get with just one setting (ie. N64's frame buffer emulation)
I can't speak about how well Quake 3 ran on Pi 3 as I only played it on Pi 4, but I had set it up on the Pi 3 so I know it was possible. I don't know anything about Vulkan drivers. Currently Quake 3 runs a treat on the Pi 4.
Likewise I wouldn't believe everything you see on YouTube. At the moment there isn't one system in my setup (over 100) I'm not getting value out of. But if I believed everything I read I'd have never attempted to set up the N64 or the Saturn. You just have to be willing to spend a bit of time tinkering with these more complex and/or obscure systems.I'll be waiting for your rescinded statement concerning PS1 emulation ^^
-
@zering Also Quake 3 by the time the Vulkan driver comes out for Pi4 would be a decent benchmark for the Pi4 system because if it maintains 100+fps regardless of max graphical setting, how many bots are in the map in Skirmish etc it would show how far the Pi's have come and that they can do much more than just emulating Sega Genesis and SNES. =)
Also it's worth noting an unofficial Android OS exists for the Pi
and somebody tested Asphalt 8 on it, seems to run pretty good if it is not fake. -
@agtrigormortis Quake 3 would be a nice benchmark if some crazy people (some of whom are active here) hadn't already ran Doom 3 on the pi ^^
-
@zering A PC the size of a fist running first person shooters is a feat in itself ^^
I have to wait for an extra fan to get delivered before I can finish my Pi4.
There's already an intake fan on the heatsink itself, but I want to install a 3.3 volt fan for removal of hot air so air circulates more efficiently inside the case. Not much good using the thing if it throttles.
I don't know if Quake 3 will work without Vulkan on the Pi4, it's probably best if I just wait for the driver to get released. There are standard video drivers on the Pi but they're not going to be great for gaming.
-
@agtrigormortis I'm telling you that it works, I've tried it myself ^^
The Pi handily runs quite a few FPSes using source ports. Outside of the official distribution some people here have managed Half-Life, Return to Castle Wolfenstein, Hexen 2, Quake 1 and 2, etc etc...Edit : Actually Quake 1 and 2 are part of the official distribution, silly me.
-
@zering Like my default interpretation is a lot of PC games wouldn't work because they would first have to be recompiled to work on ARM, but from what you're telling me it looks like they already have been. =)
I'll need to see if any of the GOG content is compiled to work on ARM
seriously would be fun to try. -
@agtrigormortis Most of my GOG software runs on the Pi through appropriate source ports or DOSBox.
The only things I've struggled with are DOS CD games as the Gog version seems to lack the executable/CD image.Going back on the subject of the N64, I think you'll find that aside from Goldeneye which is tricky to get running well (but feasible with some compromises), the Pi 4 does pretty well with the consoles various FPS games.
-
@zering we also need to be careful not to illegally distribute our retro games because even giving copies to friends could land us in trouble. Not sure we'd get to keep our copies if we got caught doing that either.
I know some games are impossible to get outside of digital distribution and flea-market sales, but copyright holders and courts wouldn't care about that, if a copyright holder gets upset about it they will sue.
I've got a game in my collection I'd like to try on my Raspberry Pi 4 after xmas and really don't want to lose, from Ubisoft. If it's not finicky with the executable it should work.

It still works but it isn't .IMG or .iso, I forget what it was in the cases I saw.
-
@adambegood Yeah I've seen that too. I don't remember the exact format either but I seem to recall DOSBox refusing to mount it.
