Tennis works using the A-OS but produces 7 invalid opcodes during the title phase. It fails under B-OS or XL/XE modes. Did the original work under all systems?
No player/missiles over the GTIA dashboard. Other than this it seems to work OK.
This program works OK but the Emulator reports two invalid opcodes when the title is displayed: $e7 at address $0489 and $02 at address $048a.
This program doesn't look like its working properly. I can't remember what the original did so I can't describe the problem any better.
Screen Display is incorrect.
The game seems to work OK except that the man appears to be able to fall through the floor rather easily. I'm not sure how much of a problems this is becauses the original running on a real atari suffered from the same problem - just not to the same extent.
This program is rather annoying. It seems to work OK but the player appears in the middle of a playfield element causing instant death.
Can't climb ladders - or have I forgotten how to play it!
Ship blows up on landing - or am I landing in the wrong place!
Can't hit anything.
The first level now works OK but then it fails.
Some graphics are corrupted.
Can't see computers moves - colours are wrong.
Graphic Elements that should be white flash white-black-white... the clouds for example.
Fails straight away.
Blank Screen.
Emulator hangs.
Problem starting the game.
Wierd problem with Joystick. It could be related to the problem I had with Caverns of Mars 1 which reconfigured PORTA so that joystick 2 lines became outputs instead of inputs. The joystick would then return the values $00-$0f only. This problem has been fixed but it could be something similar.
Freezes.
Unable to select the number of players.
Unable to start the game.
Emulator Crashes.
