First sorry my english, I always use a trick for redirecting save files in DOS games for games running from CD-ROMs that try to write savegames

For example I was playing Igor: Objective Uikokahonia but the game is 10mb, not much in modern times, but a lot for my 286 machine, then I want to convert to CD

I check the exe and dat files, and found it tries to save files using a hardcoded filename like:

1JUEGOSAL.0U  (4A 55 45 47 4F 53 41 4C 2E 30 55)

I patched the executable and replaced that filename with:

1F:\IGORS.0U (46 3A 5C 49 47 4F 52 53 2E 30 55)

Then I used the DOS command:

SUBST F: C:\GAMES\IGOR

I create a bat with the game and burn with the game

1@ECHO OFF
2SUBST F: C:\GAMES\IGOR
3IGOR.EXE
4SUBST F: /D

This work, but deppend to have the luck to find the game save to a fixed names, strings, etc

Any ideas guy for a better/easy way to convert HDD games to CD? something not to fix?

thanks a lot
