You are the only person I've heard of who has had issues with a 7800. I know it's worked for others. Anybody else had 7800 issues? Regardless, it's a 2600 game. Can't promise compatibility.
You've played it with both difficulty switches set to A, right?
There will not be a 7800 version. At least not by me.
He wrote the guide based on his observations, not all of which are completely accurate....
Excellent - thanks for the responses.
I double checked gameplay on my 7800. I can get through the lvl 3 open door the first time I go through it. If I die and reset then every time I try to go through the door, the game sends me back to the title. I also got sent back by the faerie and the same thing happened. Perhaps a value gets stored in memory to record the door is open or something and the 7800 doesn't like it.
I was able to beat the game on BB & AA during my first play session. The dragon was in the same place both times and I froze the demon and pounded on him. That prompted me to call the game too easy which I think it is. Reading this thread reveals that you may have had the same suspicion during development. Its an excellent game regardless but seems like a missed opportunity to add a harder game variation.
Thanks for the inside info on the guide
UPDATE - I tested RC4 (from this thread) on my 7800 with the Harmony cart and it worked fine. I'm going to contact Al and see if he will replace the cart I bought from AA as it might be defective somehow. It is also now giving me problems on a 2600.
