Hello, i'm trying to revive my old stuff, mainly old games i coded around year 2000 in TP7 using XVGA unit.
One of my games cannot run properly, levels get scrumbled when they are loaded when game is ran from dosbox.
i tried virtualbox with dos and game works ok there.
weird thing is, that when i compile and run game in TP7 (started in dosbox), game runs properly.
also when i run DOSshell from TP7, i can run game and it is ok.
i just cannot run it properly directly from dosbox as standalone binary exe.
(i also tried to run newly compiled EXE directly, same weird stuff.)

i cannot figure out what could cause this.

I also found other weird behavior. After i switched TP7 compiler to perform range checking (runtime error 201), i'm getting this error when running standalone exe, but this error won't popup when it is ran from TP7.

any idea?

i just tried to install GLIDOS, a ran game in dosbox mode and it works.

but when i try to run game without glidos launcher, directly with dosbox which is in glidos folder, it does not work.

there must be something specific in configuration, but i dont know where to look...

Try loadfix with various allocation sizes.
