Do you mean that old russian game where you drove a frog? It had digitised pc speaker sounds (and voices) and used Borland's BGI libraries for graphics. Probably built using Turbo Pascal. I remember that it was a bitch to run outside real ms-dos, though. There is little chance that digitised internal speaker sound works in modern computer (timing issues?) Got one copy somewhere. I have to test it... Will post back... soon.

Yes, it is.
I have two software. The first was found in internet (perest.zip)(http://www.the-underdogs.org/game.php?id=2725), the second was the version in my old 386 (pere.zip).
Thank for your help.

There is another thread talking about this game HERE

Tested my copy. Built using Turbo C++ 3.0 - It works quite well under DOSBox except for the digitised sound. The other sounds are just awful. It runs like shit under a regular CMD.EXE window, btw (big timing issues because of digitised sound routines). So your best bet is to use DOSBox. 😎

Ok, i've just finised to test with DOSBox and VDMSound2 and it's ok. Only a question. Can i use bosbox in full screen? Thanks a lot for your help.
