NES Cropping/Overscan Issue

edmaul69

@dover19 i just noticed it is cut off on all 4 sides. you need to adjust the overscan in /boot/config.txt

Actually that only affects EmulationStation, it never seems to affect the emulators. Also, what seems like black bars all around is just my black tv.

@dover19 On my pi it affects everything. Overscan is a system level setting.

I'm actually using overscan though, got the top and bottom at -16 cause I had black bars, but like I said, it only seems to affect the front-end.

@dover19 trust me, its your whole system. I noticed there are no black bars on the side. Thats why i know this is the problem. Change to a theme that has no black borders. Then set all 4 overscans to -25 so you see black on all 4 sides. Then start going down by increments of 5 until you get close to the edge. Then reduce down in increments of 1. Note that the sides and top/bottom might be different numbers.

@dover19

Is your overscan_scale= set to 1 in /boot/config.txt?

dover19

@edmaul69 so I followed these instructions and ended up with:
overscan_left=0
overscan_right=0
overscan_top=-19
overscan_bottom=-19

Also, yes my overscan_scale is set to 1.

Still though, it's cut at the bottom while playing NES. I see no difference whatsoever.

I'm sure I've seen before and I seem to remember having to put some code in the NES configuration.

@dover19 yeah not sure. I never had to add anything other than the overscan. So if you look at my pic you will see the top is getting cut off too.

I was finally able to fix this!

In case anyone else is going crazy playing with the boot overscan options and not getting anywhere with the NES cropping issue, here's what I had to do:

Edit the retroarch-core-options.cfg file located in /opt/retropie/configs/all.

Depending on what NES core you're using edit either fceumm_overscan = "enabled " or nestopia_overscan_v = "enabled ". Obviously, change enabled to disabled.

@dover19 note you don't have to do this manually - it can be changed from within RGUI when in a game.
