@myst Thanks, great!
I can imagine, it‘s not too easy finding hd graphics that match...
Here some ideas, I guess you could find some usable material on the internet:
coleco:
donkey kong (classic)
dos:
warcraft 2 or command & conquer
dreamcast:
resident evil (code veronica)
fba_libretro:
pacman
fds:
super mario bros
pcenginecd:
prince of persia
psp:
lumines or need for speed
sg1000:
difficult... maybe something from game „flicky“
