I think it's a great game! But....

Could it be a problem playing this with the "older" ZXpand? I have the UDG board, the AY-Board and its starting ok, but when I die before the first "cave" and come a second time to this area the game crashes each time.
I've upgraded my ZXpand to firmware 2.61.

Someone else has reported this :( I haven't found the problem yet - I will post here if I do.

Oddly enough I find the lastest incarnation of Dragon screws up Eighty One at this point, not tried real zeddy yet.

For me, the game hangs in a cave. If I understood correctly, then the zxpand joystick function does not work yet?

The latest build has the cave bug fixed. Thanks to jungsi for pointing it out :oops:

Joystick support was failing for users of the classic/ay setup, but that is now fixed. Please ensure that the ZXpand classic has the latest (2.62) firmware flashed.

I checked yesterday. The joystick works, but the program continues to hang at the beginning of the cave :roll:

Why do I see such graphical glitches? I use a UDG4ZXPand and a ZXPand+

Wow... I would first try cleaning the edge connector on the zeddy itself. I don't suppose by any chance you have another zeddy you could try it with and if the problem still persists then I will try to resolve the issue or replace the UDG board.

Cleaned the edge connector and updated to latest ZXpand+ FW 1.12 - no change. I do have another Zeddy with Composite Mod (ZX8-CB), but that one refuses to work with the ZXpand at all. I have two more ZX81, but un-modded and my displays are too modern to handle the RF signal.

I believe I can see two effects:
1.) Real glitches
2.) Fine vertical lines on black areas - I can also see this on the "Bad apple" demo
