Well maybe you have docs of that program and can see what graphics
cards it actually supports.

I've found in a bbs mirror an "infinity machine", it is a tsr and seems a cheats collection.
Is it the one in attachment ?

If it's that one,there is not a file that explains how to use it but it seems running in vga only.
The command line help (redirected to a txt) shows:

Infinty Machine: The Universal Gamecheater - Version 1.5 ( 03/05/95 )
(c) Copyright 1993-94 REM Software, All Rights Reserved. Commercial Version.

Usage: INFINITY [options]

/s:method Specify swap method. ( method = XMS, EMS or FILE )
/u Remove Infinity Machine from memory.
/x Enable alternative keyboard activation for DOS extendors.
/timer Enable alternative timer routine.
/? Command line help.

Yeah, that's the one. And there were no docs in my folder either on how to use it.

It's a "terminate and stay resident" program and there are two hot-key mode for the "call up" :
"Print" key if it was started as "infinity" and "dubble press the left shift" if it was started as "infinity /x".
The first one doesn't works on my keyboard, the 2nd one shows errors in status window (see attachment).
.

I've tried some methods, though none of them work.
