@125scratch Agreed as they were rendered by either the hardware or the coding. This one like the Vectrex rip were done by screenshots and outside of certain circumstances (or has a bitmap version on another system like Elite or the Atari Star Wars game) shouldn't really be here.

Just as a personal opinion, if the sheet was to get resized then it might look different than if the vector graphics got rendered at a different resolution. There is that possibility.

Usually though Superjustinbros rips with sprite boundary boxes or how they appear in the tile viewer so this must be either an early rip or if it does appear like that in MAME's background viewer...

I wouldn't think it would be possible to rip vector games. These seem to be taken from screenshots.

It's pretty cool to see some vector graphic sheets. I wonder if the Vectrex is possible to rip without trouble.
