Tritorn

Many thanks!

I've got all the items you have at your first screenshot. How can I reach this screen with the big gray dragon?

Yeah, I must have stumbled on that site before.
There's also a more elaborate map there:

Let's look at that map.
To get to the dragon, you have to eventually be in the lower right section of this map.

First, you get to the red/pink chamber at the top, with dragons and zods.
When you kill enough dragons (or zods, don't remember), the pile of stones above will change into a door.

When you enter that door, you reach another red/pink chamber, depicted below.
There, you have to shoot some magic balls against the most right pile of stones and an entrance will appear.
This leads to the final section of the game which is verrrrry nasty, including #$@%loads of enemies, tough jumps and real dead ends.

BTW think I goofed, there's 2 shields but only 1 sword. oO

Good luck!

P.S. in order to make it harder for you to advance through the final dungeons,
the game will play a trick on you by 'wrapping around' a line of certain screens.
You'll know it when you get there.
Enter a screen from the right and immediately return left to 'break the spell'.

Nope, insufficient level, but judging from your screenshot, you do have enough STR (max. I think?), so it should be possible.

Hmmm.
Well, if you look here:

This guy can't beat it, either, even with 1900 STR.

Apparently, you need the crown to beat the dragon!

To get the crown, you have to cast 'flash' on a certain rock, and the passage to get the crown will be unlocked.

I found the game ending at Youtube (SPOILER!!!):

The first comment tells that the error message that appears at the final room only happens in BlueMSX. Emulator bug?
