16bit debugger for XP?

[sendersu]

From my past experience I could recommend some tools...

for example - DosBox

DOSBox is emulator software that emulates an IBM PC compatible computer running MS-DOS. It is intended especially for use with old PC games. DOSBox is free software.

DOSBox can be used to run old MS-DOS software, especially games, that would otherwise not work on modern computers.

Thanks to you all, softice is the best for me because I have used it before. In all honesty I forgot about it. A great pity there is not an updated version of TRW that was very good and very quick too!
