But why isn't it being adjusted by default ? As-is PESTUB creates a faulty PE, just DPMILD and ME/9x don't care

There are 2 (two !) problems:

- PESTUB fails to adjust SizeOfHeaders by default, problem for any stub bigger than original, including DPMIST32.BIN
- (Headers size < lowest RVA) - problem only for big stubs, cca > 3 KiB, PE needs rellocating

This has recently been discussed in other forum also

But if you can compile then you should be able to raise those RVA's ...

The other solution (usable also if you don't have the PE source / can't compile it):

[MZ-stub + loader, < 3 KiB][PE ... ... ...][here additional DOS stuff]
