Pentium III or higher
Direct Draw Compliant, Hardware Accelerated Video Card, 16MB minimum
DirectX 7.0 with drivers
Video and Sound card drivers are extremely important, download the latest drivers.
If you have any questions about your 2D hardware consult the system info dialog box. If you video hardware doesn't support stretching to a window Direct Draw will emulate this function via software, lowering performance in windowed mode severely. Fullscreen might be faster.
Generally speaking, if you have good luck running most DirectX applications, Jnes will be no different. However, if you happen to own a really old sound card that is no longer supported, or your video card hasn't seen updated drivers in a few years (old S3 and ATI cards) than your risking compatibility, I can't make any guarantee that it will perform well.
Look in Help/System Info for more DirectDraw info on your card, all the features are important, the more you lack, the more time Direct Draw takes, which takes time away from Jnes. The following color formats are supported: RGB 15/16/24/32
