New tek-demo from Bodo (max hires)

Post by yerzmyey »

Static stuff, but as usual impressive. <EDIT - not static at all! Read a post below! ;) >

DOWNLOAD: http://forum.tlienhard.com/phpBB3/downl ... hp?id=1084
Resolution of the screen: 320x240 (like in MaxDemo).
Worth to see.

Not static at all. You need to read the manual ;)
Shift-5 to Shift-8 moves the screen around.
In case it gets ilegible (your monitor not liking the position) Shift-0 restores to the initial coordinates :D
The default position was evalutated to fit into the ZX2000 LCD optimal.
B0D0 would like feedback wether this works properly in 60Hz. If anybody would be so kind to test and leave him a note he would appreciate it.

So it's a moving "game", just without a highscore, and just a single level :lol:
It's the kind of game even I am able to handle :roll:

P.S.: B0D0's name is in hex, there are no small letters and no 'o's, just 45264 in hex 8-)
In theory, there is no difference between theory and practice. But, in practice, there is.

Tried it on my CPLD-based ZX81, and works fine. Image is stable both on 50 and 60 Hz, and stays stable when moved around.

@ 50 Hz, image is centered on my old CRT TV when I move it 3 pixels to the left, and about 15 pixels down (so initial position is towards upper right corner). @ 60 Hz, initial horizontal position is okay, it only moves 5 pixels down and still the part above "TESTBILD" falls outside the visible area (due to increased vertical height, which is the same whenever this CRT gets a 60 Hz signal).
