I can confirm - 4MB of memory crashes the game.  It crashes regardless if it's run from floppy or hard drive.

 

Tested on my 520ST / 4MB / TOS 1.04 and in Hatari as well.

Are you seeing the crash only on real hardware or hatari also?  Here it is only crashing on real hardware, hatari at 4mb runs it fine.

Both.  Hatari and the real 520ST are configured the same..

 

Anyone should be able to confirm this.

Did the French version also fail in this way?

 

I've never tried the French version before now, but it seems the answer is yes it does.

 

It is 100% a problem with 4MB in this configuration.  Running something like phystop (on the real 520ST) to lower available memory to 1MB will allow it run.

Wow... I wonder what it would do on a 4mb Falcon?  (It runs on my 14mb Falcon).

 

Hopefully I'll give it a whirl with the TT soon.

 

Though it does surprise me it works with 14mb... I've heard of games not working with more than 1mb... we're all familiar with the memory expansions that had a switch to "limit" it to 1mb for those times..... but to be specific to 4mb seems odd.

 

@lp060 think we might need a GFA Basic guru on this one.

ok,

 

for now you are the only person with this problem (the game exists since sevaral month with the french version)

 

Need someone else with this problem to start checking.

 

 

@drfloyd see above, there is a second user confirming a crash - @remowilliams.

Very strange, it works on hatari here (launched from desktop) with the same config as my STE (which as noted has the 2 bomb crash).  Wonder what is going on?

Ah, if I launch from the AUTO folder on hatari it crashes also.

 

I am thinking this games use GEM/AES calls and has to be run from the Desktop?

Could be true. Far as I know he used the original GFA which can have AES/VDI calls internally used by various commands. Soon as you use such commands the compiler will include the AES/VDI startup code. In the end the app will then rely on these parts of the OS which of course do not work from the auto folder. I don't have access to the source code, so I'm only guessing. 😉

Traced a little in hatari. It crashes in this trap #2 so there is an AES call:

 

0004b592 223c 0004 b6a4           move.l #$0004b6a4,d1
0004b598 7073                     moveq #$73,d0
0004b59a 4e42                     trap #$02

I made a version which uses PPera's HAGE system so it can run from the AUTO folder and it works now on my STE.  HAGE loads a full TOS1.04/AES into high ram and then autoruns the program.  The only caveat is that the HAGE version needs minimum 2MB instead of the 1MB for the normal version.

Typically "moveq #$C8,d0" would be an AES call. This looks like a VDI call. Perhaps he didn't stick entirely to Line-A gfx commands. Either way it does appear to rely on a component of GEM.

Ok, but being realistic.... the problem was just running it from the auto folder?  I mean, it seems silly to me to go to all the trouble and to double the memory requirement as well, just to be able to run from the auto folder instead of just saving the desktop with the A drive open so you can just double click to start.

 

Or am I missing something?

hello,

 

i try to follow : is the problem coming from running it from an auto folder ?

 

The core game problem I demonstrated is running the game, from the desktop, on a TOS 1.04 machine with 4MB

 

If you run it with 4MB the game crashes as shown above (both English and French game versions), if you run it with 1MB it runs properly.

 

You can test this in Hatari.

That is incorrect.

 

On a real 520ST with TOS 1.04, with 4MB - the real machine I have right here on my desk, it crashes exactly the same way.  That is how I found this out in the first place.

Aren't there a few different methods of getting a 520ST to 4mb?  I have never owned one myself.  I ask as some of the mods I have seen seem kind of janky, not that I am suggesting your setup is.  Was just wondering if it could be a big in a particular implementation over another.

 

Only STs I have all have SIMM slots.

There are definitely different ways.  

 

However since this machine is exhibiting no issues, and Hatari crashes exactly the same way in exactly the same configuration tells you that the machine is not the issue.
