New Port - VVVVVV

langest

Which Pi are you guys running on?
I am using an overclocked Pi4 and am getting pretty crappy framerate. Is there anything that I can configure? Compile flags for instance.

Thanks

@langest on the pi3B things run smooth as butter. Maybe it's something that can be addressed with compiler flags, but what resolution are you on?

Game runs for me, but framerate is quite laggy, feels half the speed it should have.
I'm running on a rpi4, I shouldn't have any problems... any ideas?

I noticed this comment only now. I'm on Pi4 and have the same exact issue :/ if feels like it skips every second frame. I've got the same issue with a couple of other ports, namely Prince of Persia.`

pjft

@pamput as asked earlier, what resolution is the pi using?

langest

@pjft
No settings changed in vvvvvv, tried to see if there was such an option. Running my pi at 1920×1080.

pjft

@langest it wasn't about vvvvvv per se, but wondering if it could be similar to this: https://retropie.org.uk/forum/topic/24602/disappearing-sprites-possible-frameskip-issue

Great stuff. I already own this on my phone but will buy it on GOG just to be able to put it on my Pi!
I wish all new retrogames would be compatible with the Pi systems. Hotline Miami would be on the top of my list.

It was my initial guess already. I've checked with tvservice -s and forced it via runcommand, I'm running 1920x1080@60Hz :/

state 0xa [HDMI CUSTOM RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive

@pamput I am at a loss then for now. I need to get my pi 4 set up and test things out. Might just be a compiler flags thing for sure.

pamput

@pjft no worries, I appreciate the help. I'm happy to run any kind of debug for you if you need it.

So, I confirm that on the Pi4 we do get the mouse pointer there (extremely awkward :) ) even on my DS3, but also that the performance is indeed not optimal.

Let me look into it for a bit and see if I can come up with anything.

The CPU is at 30%, so that's not the framerate bottleneck. Might be related to the graphics driver.

EDIT: the mouse cursor seems to be related to a commit that took place recently.
https://github.com/TerryCavanagh/VVVVVV/commit/adde99dfe6f75d58ea8ff5284fed76f14d3e0154

and EDIT: it might just be that we're out of luck here until the actual graphic drivers are improved.

Does anyone know if I can extract the data.zip file after purchasing the game from here: https://www.humblebundle.com/store/vvvvvv
It's only € 1.34 there currently. :)

pjft

@BobHarris I'd imagine you can - it's DRM-free for Mac, Windows and Linux, so you should be able to just go at it.

BobHarris

@pjft Ok thanks yes it was mostly DRM I was worried about.

Thanks for the heads up on this. Got it nicely installed on my Pi3b+ no issues. Yes it does have the cursor also but that doesn't bother me. The performance is absolutely brilliant, and what a great game! I'd never played it before but it's amazing fun.

Can I just ask - I installed from source and it all went well, but I think I now have a folder in /opt called vc. I didn't have this before so I'm assuming this is as a result of the source install. Can this folder now be deleted or is it still a crucial working directory? Many thanks all. :-)

pjft

I always recall having /opt/vc, so I wouldn't touch it :)

If you want to disable the cursor, you can probably checkout an older commit and compile that source version. I can try to help with that later.

@pamput and @langest and everyone else on the Rpi4. First of all, huge thanks to @psyke83 as it was his guidance that helped address this. After some troubleshooting and back and forth I do confirm that I have gotten this to run as smooth as possible on the Pi4 :)

Summary:

Install xorg if it isn't installed. An easy way to go about it is to install Minecraft via RetroPie-Setup (you can probably uninstall it afterwards), as it'll install that dependency.
Update runcommand from RetroPie-Setup > Core Packages
On /opt/retropie/configs/ports/vvvvvv/saves/unlock.vvvmake sure that fullscreen is set to 0. <fullscreen>0</fullscreen>
On /opt/retropie/configs/ports/vvvvvv/emulators.cfg add XINIT:before the command. It should look like:

vvvvvv = "XINIT:/opt/retropie/ports/vvvvvv/VVVVVV"
default = "vvvvvv"

After this, enjoy!

Yes you're right. For some reason I thought it was a new directory. I've only just started setting up a new fresh install from scratch. I've been running the same version for some time and thought it time to upgrade, and I didn't remember the directory. Having a look on my old system shows it is indeed there too, so I'll leave it alone. Many thanks!

pamput

@pjft, still no good for me :( All I get now is a still image of the word "Pre" in the middle of the screen (a piece of the word "Press" usually shown at the beginning of the game). :( Other than that the game is frozen.

pjft

@pamput edit the config file and set full screen to zero, as described. You're almost there.

Edit: noticed that in the text I said zero (correct) but in the example it read 1 (wrong). Fixed it now.
