Hello raga,
I want to debug a 16 bit program but Ollydbg don't open it.
What i do?

Ollydbg is a 32 bit debugger, for 16 bits use SOFTICE in W98.

Ricardo

Alternative is to use Trw v1.23 from Liutaotao & Zhunanhao
It will handle old 16-bit "NE" executables.

trw is for windows 9x only?
I have Xp!!

Then try to debug it with "Borland Turbo Debugger v5.5"

Search for "td55.zip" in your favourite web browser in case you don't have it.

there is a tr252 by liutaotoa it handles 16bit executables in nt (i ve used in in w2k) may be you should look for it
