Require assistance with Altirra

[BLASTERS]

Greetings one and all 

i require some assistance with Altirra.

 

I am trying to load the last squadron game file into Altirra but every time i try to do so the screen reverts back to the atari basic screen.

 

I have reset Altirra to default settings several times. but the game file will never load.

 

i have contacted two friends before i have come here who have helped me and the game loads up fine for them but will not load up for me.

 

i have followed their instructions and settings that they have on their Altirra profile and still i am unable load this game.

 

i am using windows 10 with Altirra 4.01 

i use Altirra 64 executable file as my friends have informed me to do so but still i am unable to get this file to load. 

 

anybody have any ideas how i would be able to solve his problem?

 

my profile on Altirra is as follows:

 

600/800xl

ntsc

6502

320k rambo disk

no basic selected

 

its all pretty much standard / default set up

Are you using Altirra system roms or Atari system roms?  Do other games work?
