I was clicking through the topics and found this that is pretty much what I just tried to post about, sorry I can’t see how to delete my post but this post seems to be the same thing….so here is my addition(lots from the other post)

I have a 4k monitor and when playing some of the 8 &16bit stuff (atari, sega master, nes, snes and gamecube) the bezel shows up normal but the game only shows in the upper left quarter of the screen in the bezel (1080p I think),

arcade classics, ps2 &3 and wii u doesn’t have this issue.

When I change the display resolution to 1080p before opening bitwars everything works and is the correct size, and using the flash drive that bitwars is on with a handheld PC at 1080p has no issues, just my desktop that has a 4k monitor so I guess a lame work around is to change the resolution to 1080p before opening bitwars…

I’m thinking its an emulator settings issue maybe, like retroarch? where would the config file for that setting be in the bitwars file structure and more importantly what setting would I need to change to have the emulator use the full display with a 4k display or adjust automatically to the displays resolution? 

oh and if anyone has some references or sites that talk about how to add or subtract games/systems from bitwars plz share as I am pretty new at this but would love to learn more about the file structure and the emulators used.

Thanks for any help in advance

I figured out how to edit….I made a post  “how to adjust CoinOPS LEGENDS 2 Bit Wars resolution when launching 8&16 bit games” with the info in this post before I found this post, so if that post needs to be deleted I understand
