I've tried on DOSBox for many years... however, I eventually got my old pentium 1 system again... never looked back.
The problem with emulators is that they are not seamless and I require many variables to be fulfilled:
#1 3dfx support, including for certain drivers (some games I have will only work with monster 3D drivers, others with later stock 3dfx drivers, etc: requiring different 3dfx-equipped computers).
#2 MS-DOS support, along with real hardware: I can't stand emulated FM chips, and because my favourite OPL3 synthesizer is a clone, no emulators exist for it.
#3 Windows 9x support.
#4 emulators don't account for a full hardware experience (including PROPER CRT monitor, mechanical keyboard, etc)
I have some DOS games which have certain elements running in windows 9x (like map editors), and some games ONLY work with windows 9x: but then I may want to play a DOS game later on after that.... or what if it requites glide? etc.
So it's a crazy combination of discreet hardware I want to run, as well as a whole multitude of different software... which is sometimes dependent on specific hardware. In order to emulate all of the games I play, it would require so many emulators piled on top of one another that I just don't it's possible?
I certainly wasn't able to get some games running with emulators (and had a lot of trouble getting them working even with hardware as it has to be sooooo specific).
I've created two 98 machines to fulfill both ranges. A P1 233 with a voodoo 2, and a P4 northwood with a voodoo 4500 AGP 4x.
