He realized that when a game platform dies, so does all of the software, and saw the opportunity to keep these games alive on the PC, since PCs had finally hit the level where it was possible in terms of 3D cards, processors, etc. First, is the ability to use 3D hardware acceleration to increase the graphics resolution to PC-quality, which is huge. I personally play PSX games on my laptop, on planes, trains, and on the road. The hardware acceleration and the freedom to play PSX games on PCs are the two main things. Any V3, TNT2, Rage Pro or better card with 16Mb RAM or more is what we recommend for the best quality.

It has severly limited our ability to grow the business and be as profitable as we could be.
