240p composite top portion is crooked.

@galaga said in 240p composite top portion is crooked.:

@cyperghost Sorry for going off topic, but I'm having the same issue as the OP and the framebuffer lines helped (mine are at 320 and 240)! It fixes the issue in the terminal but not on RetroPie.

you need overscan_scale=1 also, as per the example above.

Galaga

@dankcushions I had overscan_scale=1 but I'm not sure if it helped. I'll try adding it again though.

EDIT: Yeah didn't fix it, here's my thread for more details as I don't want to completely steal OP's thread: https://retropie.org.uk/forum/topic/12572/strange-issue-with-crt/21

@galaga im ok with the thread jack. We are trying to accomplish the same thing.

edmaul69

none of these settings fixed my issue, but i really recommend this shader to square your pixels. in super mario bros. for the nes, the bushed would change as you ran across the screen. looked absolutely horrendous. this made it beautiful again.

Galaga

@edmaul69 Oh ok lol. It's weird that that same issue exists on both composite and HDMI (going to RGB).

Galaga

Ok so I tried a framebuffer of 480x272, and it was a weird widescreen aspect ratio. But once RetroPie starts to load, it went back to 320x240. I think RetroPie for some reason isn't using the overscan/framebuffer settings on config.txt (and yes I have overscan_scale=1).

cyperghost

frambuffer 420x272 is (was) just for SDTV 4,3" display

Galaga

@cyperghost Oops. Well I actually just found something strange. At the bottom of config.txt there is a second overscan_scale=1 that was commented. I'm going to uncomment it and see what happens.

EDIT: Nope didn't work :( I'm going to try removing the extra one.

Galaga

Yep that didn't work either. I have no clue what the hell is going on >:(

dankcushions

@galaga post your config.txt

Galaga

@dankcushions Ok, I'll figure out a way to do that after the Pi is done updating.

dankcushions

@galaga what did you update?

Galaga

@dankcushions Uh RetroPie and Raspbian through the RetroPie settings thingy.

dankcushions

@galaga if that's updated you to raspbian stretch, it's game over.

dankcushions

@galaga please use proper markup as per https://retropie.org.uk/forum/topic/3/read-this-first - we can't read that properly

Galaga

@dankcushions Ok I'll reupload it.

Galaga

@dankcushions Edited it.

@Galaga Help! What a mess!
@dankcushions Sorry for getting into this thread :(

Disable all HDMI things at first!

@cyperghost I'm using a HDMI to VGA adapter though...
