I use Retro Games > MAME to run my MAME 2000 romsets. And also tried MAME 2003 Plus romsets.
In many games, like 1941.zip, 19xx.zip, the video size is wrong. It only shows a part of the graphics. Left and right side of the screen is black. The airplane can fly out of visible area…
The romset link is here https://archive.org/download/MAME_2003-Plus_Reference_Set_2018/roms/19xx.zip
In RetroArch > MAME 2003 Plus, the issue doesn’t exists.
