overscan when using a arcade bezel #7

Closed txcx closed 7 years ago

hi,

first i want to thank you for this little nice project, gonna help me to get a fast nice setting of crt scanlines, but i stumpled upon an issue.

i use a lcd display through hdmi and had a black border at retropie first time setup. so i tried to disable this, i can't remember what cfg or settings file i edited but i got the display now exactly full covered.

weeks after that i tried yesterday our rp video manager, everything seems fine but i discovered if i start final fight for mame the arcade bezels (i've turned them on) covers parts of the game, 20-30% are under the bezel (each side), and i don't know why.

is there a way to reset my own overscan settings or is it a issue with the video manager maybe?

thank you for any help :) keep up the good work.

Thanks for the comments. The arcade bezels assume a 1080p resolution will be used. If you are running a different resolution, you can compensate for this by editing the /home/pi/RetroPie/roms/mame-libretro/romname.zip.cfg

Thanks for the information, i could remove a initial setting (640x480) in retroarch.cfg done by myself, this helped me a bit, anyhow there is still a bit covered by the bezel (e.g. final fight world set in mame, around .75 inch on each side), maybe i have to play with the overscan settings?

For an example showing how to tweak the output, try the invinco.zip.cfg file. I'd leave the retroarch.cfg alone. Bear in mind the aspect ratio, i.e final fight is 384x224 (1.71:1) https://en.wikipedia.org/wiki/Final_Fight
