Some PI questions from a noobie - Hoping for some help. Thank you all !

Hoping some of the resident PI experts could help a noobie out.
I've got a Raspberry Pi that I'm using to power my Punch-Out bartop.
I've got a few questions and I'm hoping yall could help.

ONE - I have a 32GB Image for my PI. The image was designed for a 32GB card. I extracted it, put
it on the card and had no issues. Within the Pi menu it shows card is 96% full.
I saw something about expanding the file system, I'm wondering if that would be
necessary in this case ? (as the image was 32BG and used on a 32GB card).
I watched a video on YouTube, but the menu option he showed doesn't appear as such on my Pi menu. I'm using Launch Box.

TWO - MAME will not save my control configuration.  EDIT - Furthermore, I attempted to change the volume for my Midway games in MAME (MK3, NBA JAM). MAME would not retain the volume adjustments. I'm lost here for what to do.

THREE - I  referenced this in a previous thread. I get screen flicker on the main Pi
menu. But the flicker appears to stop when a game is loaded. I assume the resolution when playing the games is perhaps less than when on the main menu. I'm using an HDMI to VGA adapter. I found a video on YouTube where someone was using a similar device. They made a few changes to change the resolution of the Pi. I did this, but the flicker remains. I'm yet to test with a 2nd monitor, but I will. But any help or advice would be appreciated.

I'm using a Dell 2210 monitor and Raspberry Pi 3B board.

Thank you all for  your assistance

In this case, it won't be necessary.

If you loaded a smaller card image on a larger card, that would be when you would want to expand the file system.

For example, if you loaded an 8GB image on your 32GB card, the card will have up to 8GB of files and the rest of the 8GB as free space because the RasPi partition/File Allocation Table only maps the 8GB of the original card.

Expanding the file system maps the unused 24GB to the RasPi partition/File Allocation Table, giving you up to 8GB of files and 24GB of free space.   :cheers:

@ PL1 , thank you.

I didn't think it was an issue, but wanted to ask and be sure.
Now if I can crack the code with this monitor issue, and MAME not saving the config I'm off to the races.

mike boss:
I had an opportunity tonight to test out a 19" 4x3 monitor I had around the house.
I used the same HDMI to VGA adapter, however I changed the VGA cable (all be it I don't think that was the issue).
With the 19" monitor I got no screen flicker and all worked well.
I'm looking to test now with a 3rd monitor, another 22" monitor I have in the house to see if that works.
If I get no flicker with the 3rd monitor at a minimum identify that my monitor is indeed the issue.
I'll simply swap it out.

All that would remain is to figure out why my MAME configurations are not being saved.

mike boss:
So I tested a 3rd monitor I had in the house, another 22" Acer monitor.
I had no issues with this monitor either. So I can safely say it is the existing 22" monitor I have in the bartop that is the issue.

The only flicker I get now is when I escape a game and go into the main Pi menu. But its minimal and non distracting.

Before the amount of flicker was INSANE !

I've tracked down a 21.5" monitor with the same width as my existing Dell monitor (as installed in the bartop). I'll be getting that tonight for $15. I should be able to wrap up the project providing the monitor gives me no issues.

Outside of that I'm simply going to a 19" 4X3 monitor.

Still looking to find out why MAME wont save me settings.
