I can get it to work in EightyOne, but not on JSZeddy.

I'll test on real hardware tonight, when I'm home from work.

I tested it on EightyOne as picture shows.

When tested on real hardware and used with a RGBtoHDMI adapter, the screen starts to blink. It seems the sync is lost every 1/2 second.

(I haven't tested Mushroom Man yet, as my Lambda gives an unreadable video, when it gets hot. I'll try it tomorrow)

A screenshot of the video shows me the same error as earlier, text is also 1 linefeed off.

It puzzles me.

First time I tried the demo Basic program, we had this 1 line off. But when I tried again, it was ok.

Now it has occurred again in another program, and I wonder if it'll disappear when I try again tomorrow.

An error that comes and goes is not great.

we are still discovering... I will find a way. First to try is adding 1 linefeed at dfile and best a few at bottom instead of JP (HL)

MUSHROOMMAN for the Lambda 8300
-------------------------------
After MrtinB showed that QUARACTERDISPLAY was possible on the
Lambda 8300 I wanted to make a port of MUSHROOMMAN to that computer.

The first thing to do was to find how the loader of the Lambda 8300
had to be set up. After finding a workable setup I converted
quaractergenerator from the ZX81 to the Lambda.

This showed me where I had to alter the source for the ZX81 to
make it work on the Lambda. After a few tweaks the game played.

Some characters on the Lambda are different from the ZX81.
This corrupted some defined characters so I had to redefine them.
Altered graphics are the hard wall, the water, but also the number 1
in the teleporters. The layout is the same but the setup is different.
With altered character I could also change the look of a guard.
The water-graphic was the hardest graphic to redesign.

There was a small bug in my model but when solved the display was right.
Thanks to Thomas for testing so soon.
