Waooo, Ceti, this is a great thread !!! I've always wondered why the option was hidden away in most of the games... it is, I think, an amazing feature that should be included in ALL option menus
As far as I noticed, the arcade mode on Tatsujin seems to give more breathing space with identical sprites, so they (I think) use the Hires mode. I'll let you know if I know of any other games not listed on your awesome thread.
Thanks for posting the update!
Y'welcome
