   Uridium for Atari ST
        improved

ST version of Uridium is known as slow and not
well playable. Usually people blaming lack of
HW scroll support for that. But scrolling self is
actually not that bad. What is very bad is slow
ship control - it accelerates poorly, turning 180
degrees takes too much time, so hard to play,
if possible at all to finish some levels.

I went in improving it. Better scrolling is done
by blitter help. Faster controls needed lot of
tracing, code examining. 


URIBLITS.TOS -  for STE, Mega STE. Mega ST, or any ST with blitter.
512KB RAM is enough. Can run from floppy or hard drive.
Selectable start level, so you can try all them quickly.

URIDOS.TOS - version with original scroll, just controls are
improved - so any ST, STE ... 512K RAM is enough.

In case of TOS 2.06 and only 512KB RAM put desired executable
in AUTO folder, rename extension to PRG, and reboot.


Your Manta performs a 90 degree roll if you press and hold fire whilst moving up or down. 
This will enable you to manoeuvre through restricted spaces.
