Run the game, press U for Unlimited lives, then when I see the box art scan I press space to start the game.
The screen goes black and the system sits there. No disk access or anything.

Unfortunately, my Mega STE is not accessible at moment, and will be not some 10 days. I did some corrections of suspicious code, but can not test now on MSTE.

Ok, RUNME2 did the same thing.

RUNME.TOS works if you boot clean holding CONTROL..

This should be OK:  http://atari.8bitchip.info/RUNME3.ZIP


No. Same thing. One thing I noticed. In the launcher I hit M to try 8Mhz. Press enter to go back but the launcher still says 16Mhz. If I hit M again it does say it is at 8Mhz but again back at the launcher screen still says 16Mhz.

If I set my MSTE to 8Mhz in control panel before launching game, then is says 8>16 and I can hit M select 1 for 8Mhz press enter and the main screen does properly display 8Mhz.

I found silly bug in previous launchers. Corrected. Although not tested yet on real Mega STE, I'm pretty sure that it is now OK. Get it on adapt. DL page.

That did the trick! Works well. Thanks.

I was playing this tonight. Fun game.

I did notice that on all my ST machines, I get graphical glitches with the "sky".
There is a line that runs across the screen in the area of the sky and it sometimes looks weird when the screen scrolls around from running/jumping.

Just the sky, if I go lower  in the game and the sky is not in view, the graphics are solid.

I noticed that too. As usual, such effects were made not with bitmap operations, what is btw. slow and color count is limited (max 16 at once on screen). Instead it, color palette is changed at accurate screen position (line). It needs little CPU time, and we can have more than 16 colors on screen. But coding is not simple. I guess that programmers of Scooby Doo just did not it too good.
Some games solved it better, and may have over 50 colors at once on ST(E).
