It's not -that- bad, but it can be tedious. I ported some 16-bit BP code to a Delphi console app that used a homebrew windowing library that was based on direct screen writes. There is a windows console equivalent to direct screen writes that allows you access to the screen buffer. The important routines are:
AFAIK, all of these functions have been implemented in FPC. I did find a quirk in the Delphi implementation. The TCharInfo structure wouldn't work correctly for some of the calls, and I had to declare the following type to make it work:
TFixCharInfo = Record
AsciiChar : Char;
Dummy : Byte;
Attributes : Word;
I don't know if that's the case for FPC or not.
Combined with one of the free WinCRT's out there it worked fairly well. I also had to write a translator for the keyboard scancodes, but that was fairly simple.
Unfortunately, that code is owned by my employer, so I can't release it.
