Thanks for posting it!  

 

Disclaimer: I cannot guarantee this game will work.  In testing, when the game was loaded from disk, it had a 70% failure rate when you pass level 11 or 12.  

 

Seems there is a runaway condition that occurs sometimes which chews up VDP RAM and crashes the game.  I've tried to figure it out, but have been unsuccessful.

Thanks Vorticon!  I put quite a bit of work into that packaging.  :D  

 

The crash condition typically happens somewhere between levels 10 and 13.  And it doesn't happen every time.  I have attempted to debug it using Classic99, and I have watched the HeatMap during a crash.  It lights up like a Christmas tree.  :)

That sounds like a stack problem, probably a subroutine not exiting properly with a RETURN statement.

Yeah, that's kind of what I thought initially, too!  And it may well be the case. Unfortunately, it doesn't happen every time, and I'm not sure what conditions within my game cause the overrun...  

 

If I get the inclination, I'll sit down and start making up route charts.... find exactly where the train goes off the tracks.  But so far, I think I've been the only one who has experienced this thing.  And I experienced it multiple times during testing and duplicating.  Thing is, it never happened when the game was loaded from tape... so I really don't know.  :)

Then select TI BASIC like normal from the main menu.

Didn't try it but it should work.

Tried it. Works well.

Thx! (ups, reading skills are lacking 😛 )

In 1981 I programmed a Pac Man clone in TI Basic (TI PUCK - on the tigameshelf.net site) and I had a similar issue. Never figured it out at the time. In 2007 I took another look at my handwritten code and finally realized that one of the subroutines was not returning properly under specific conditions. Wait a couple of decades then take another stab at Marcus. All will be clear! 😄

I downloaded and ran the Markus game - It's a hoot! (Yes, and one does tend to:  "Die in this Tower.") It was a pleasure to recall how some of the more cleverly conceived TI Basic games had merit and considerable entertainment value. M of M certainly belongs on that list. Unfortunately, additions there are scarce.

 

The only actual annoyance I had with the game is when the wife got to level 7 on her first attempt... what's with that?

The fact that you got your wife to actually touch a TI is quite the achievement by itself...

Well, sort of. Its more along the lines of, "While I'm doing this you need to be doing that..." A variation of an "IF ... THEN..."
