+* avtbingo, avtsym14 will accept coins. PIO-1 is programmed to cause an interrupt
when coin1 is pressed (port02).
- avtnfl gets the interrupt from PIO-2, but then reads port02 (from PIO-1) to get
- the key that was pressed. Currently PIO-2 is not connected to anything in emulation.
- The interrupt routine also draws the screen.
+* avtnfl, you need to set it up before it can accept coins. However, it is random if it works
+ after doing that. If you want to try, press 7 to enter setup, press 6 to select the adjustments
+ screen, choose items with 2 and adjust them with 4. Press 6 until you exit. If you're lucky enough
+ to get it to work, 2 will enter coins, 3 will tilt (don't do that!), 6 is Draft, 1,2,4 (at least)
+ will remove cards. Don't know what the aim of the game is though.
- avtsym25 has mismatched program roms so cannot work.
