Anyone else discover that if you use a keyboard via an OTG cable on the 2600+ and type "F1" you can enter the Stella save state menu? However, It seems that because Stella only recognizes the cart dumper as a single game (regardless of title), all games will share the same save state slots. The upside; there are 1,000 save slots, so you can still save each game to a different slot (you would have to keep track of them on paper). My recommendation would be to skip every 10 slots so you have multiple slots for each title, that would still leave you with enough slots for 100 unique games. Also, "P" key pauses any game, arrow keys & "A" & "Z" are the FIRE buttons (for 2600). All seems pretty standard. I still have yet to try, but the OTG cable might also allow for using USB game controllers as well (most likely D-input devices). FYI - Hyperkin sells the "Trooper 2" Atari style USB joystick with added buttons.
