4.0 RC1 Nintendo 64 High Resolution and the conflict with 320x240

Twitch0815

Pi Model: (B, B+, 2 B etc..) Pi 3b
RetroPie Version Used: (3.5.0 or 3.6.0 etc..) 4.0 Rc1
Built From: (SD Image, Binary, Source) SD image
Guide used: (Mention if you followed a guide) https://github.com/RetroPie/RetroPie-Setup/wiki/Optimization-for-Nintendo-64
Emulator: (Name of emulator - if applicable) 64 Rice

So with the build of 4.0 RC1 there is an awesome change to the render resolution of N64 games. The forced 320x240 and thats having a great effect on games running. But for those who have or will enale High Resolution Texture packs through Rice it limits the effectiveness or ability to use them. I can get some of the effects to render by editing framebuffer resolution on a per rom basis but not fully.
Can someone fully explain what is hard coded and is it possible to allow the forced 320x240 to scale up on a per rom basis.

Take a look here:
https://github.com/RetroPie/RetroPie-Setup/wiki/Nintendo-64#tweaks

Open '/opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh' and edit line 265. Change '--resolution 320x240' to anything else.

@gizmo98 That is a good temporary fix, but as that change is great for roms that are problematic like Killer Instinct and Super Smash just roms that have extra overhead like Mario Kart and Mario 64 that I want to individually scale up like something in the runcommand menu.

It is not implemented. I thought about using retroarch render resolution settings. But it has not gone farther up to now.

How about to make a copy like /opt/retropie/emulators/mupen64plus/bin/mupen64plusHiRes.sh and add it as a separate emulator.

@bense2k
I think Twitch0815 wants a per game selectable resolution possibility. If we add a second startup script we have only two resolutions and two scripts which must be maintained. In my opinion it would be better to adapt the current render resolution runcommand.sh option somehow. This shouldn't be so hard but someone has to implement it.

Sorry to butt in - maybe something like this ? https://github.com/RetroPie/RetroPie-Setup/pull/1621

using the render resolution would be even more flexible - but requires a lot more work, so my PR may do for now (is it worth going higher res than 640x480 on the rpi anyway ?)

gizmo98

;-). This looks good. If we expect anything higher than 640x480 is too slow these two resolutions should be enough.

@Twitch0815
Do you need higher resolutions?

Twitch0815

@gizmo98
Let me test, ill have to load up a build on 3.8 I seem to remember needing 1024 at the minimum but its been a while, since I tested that.

BuZz

with the changes I just merged, it is relatively simple to add further higher resolution modes by editing /opt/retropie/configs/n64/emulators.cfg and adding a new launch line.

Twitch0815

@BuZz
To test do i reinstall mupen or full emulation station?
For a default image there should just be a launch line for 640 and 1024

BuZz

I don't agree - I think 320x240 and 640x480 is enough, but feel free to change the launch parameters to whatever resolution you want on your install.

You need to reinstall mupen64plus after updating retropie-setup.

@BuZz only time any higher resolution might make sense is on a pc. Otherwise processing of the pi won't be enough. Just my two cents.

Twitch0815

Yea this is working perfectly fine the changes submitted are great.

Sorry to drag up an old thread but is the fixed N64 rendering resolution of 320x240 the reason the games look terrible?

I posted this over on Reddit, but basically I have a new Raspberry Pi B 3, I've done a fresh download & install of Retropie 4.1, placed the ROM's in the N64 directory and if I use the gles2rice or GLideN64 video plugins it's VERY block & low resolution.

Interestingly if I use the glesN64 video plugin for Mario Kart or Super Mario 64 they both look incredible, very crisp as if they're being rendered at 1080p. Unfortunately these are the only games this works for, Zelda OoT for example looks as bad on this plugin as it does the others.

Sorry if I've missed an obvious setting? Here's the thread over at Reddit if it helps. How can I render some games at a higher resolution? I don't expect to run OoT at 1080p but if I could wind it up a little that'd be nice, on my 75" TV it's a mess.
