DOSBox is intentionally limited to 127 files. There is no way to raise this except by recompiling DOSBox. This is because very few programs (especially games) actually require that many open files and when they throw such an error message, it's commonly related to something else.

I have made a patched version which allows the files setting to be changed through the config file.

does the application work/hang/crash ?

you didn't actually said whether your patch allows what he wants or not 😀

well the files=140 requirement is usually a requirement people think they need because the application hangs,
while in reality something else might be going on. At least I've been able after debugging various of such cases

So if it hangs, there is the possibility something else is going on

True, although I didn't say that it didn't either 😜 So I guess I didn't say anything at all 😁 Anyhow, DOSBox has a static setting of 127, my patch makes it dynamic and accepts any numeric value (although any value lower than 10 is silly, below 1 is stupid and any value above 255 will cause problems and your computer will explode with strawberry jam oozing from the power supply -- or perhaps not).
