I personally use SV_ALL-SV_INFO
What is the error message you get if you use it with LEVELS?
I have not seen it in your post. Only for loading.
I get a pop-up error box stating:
Error E1513
Script crash in buttonSaveGameQuit:
OK Cancel
...when I press the "q" key, and press the "SAVE" button, with the code below.
...
function buttonSaveGameQuit()
{
result = game_save("test",7,SV_ALL-SV_INFO); // SV_LEVEL GIVES ERROR
if (result <= 0) { error("Save Error!"); }
sys_exit("123");
}
function buttonNoSaveGameQuit()
{
sys_exit("123");
}
...
