Problem Programs

This page contains a list of problems that causes the emulator problems. If you know of other programs that don't work properly please E-mail the program and a description of the problem. If you know to fix the problem you can send that as well :-)


Programs that are still playable

Atari Tennis

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?

Electra Glide

No player/missiles over the GTIA dashboard. Other than this it seems to work OK.

Pharoahs Curse

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.


Programs that work to some extent

Mouse Attack

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.

Bug Off

Screen Display is incorrect.

Caverns of Khafka

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.

Mr. M

This program is rather annoying. It seems to work OK but the player appears in the middle of a playfield element causing instant death.

Canyon Climber

Can't climb ladders - or have I forgotten how to play it!

Air Rescue II

Ship blows up on landing - or am I landing in the wrong place!

Stratos

Can't hit anything.

Gorf

The first level now works OK but then it fails.

Up Up & Away

Some graphics are corrupted.

Challenge 5

Can't see computers moves - colours are wrong.

Wing Wars

Graphic Elements that should be white flash white-black-white... the clouds for example.


Programs that don't work at all

Tapper

Fails straight away.

Race in Space

Blank Screen.

Plattermania

Emulator hangs.

Pie Man

Problem starting the game.

Burgers

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.

Moogles

Freezes.

Snapper

Unable to select the number of players.

Danger Ranger

Unable to start the game.

Senso

Emulator Crashes.
