Ixamyakxim: I'm an idiot and just made this post in the wrong thread, along with a part of a right post in said thread LOL. Where are you games installed? I'm not too up to date on DosBox issues but here's what I wrote in the other thread:
OP - silly question - are you running as Admin? Sounds to me like the issue is with DosBox having problems writing back to disc / directory to run the game.
Maybe do a test - install a DosBox GoG game to some simple directory like "C:\GoGgames\GameX" and run it as admin.
Maybe you're saving / installing your games in a funny directory (ProgramFilesX86) or with a long / complicated directory name ( \goggamebaldursgate#bestgameva!?!?LOLZ ). Some old Dosbox games don't like this and / or Windows might not want to give dosbox permission to write to subdirectories like these.
It is in programfiles(x86) - default install location. I thought I tried running as admin.
Running DosBox as admin gives:
"CONFIG:Loading primary settings from config file C:\Users\sempronius\AppData\Local\DOSBox\dosbox-0.74.conf
MIDI:Opened device:win32
One joystick reported, initializing with 4axis"
