one interesting MAME-side one is Space Ranger (arcadia)

unless I'm misunderstanding the game the 2nd button (used to launch a net) doesn't seem to function

button 2 works on all the other arcadia games, so maybe it's an interesting edge case (some mirroring?)

it's been like this since the game was marked as 'working' but IMHO it doesn't really work due to this.

haven't tried the actual Amiga release.

also haven't tried in the last few days, but I haven't seen any fixes that look likely to affect that area of the emulation.
