These games all use OpenGL libraries. They will not work without decent 3D graphics cards providing hardware-accelerated OpenGL.

The ECM format allows you to reduce the size of a typical CD image file (BIN, CDI, NRG, CCD, or any other format that uses raw sectors). It works by eliminating the Error Correction/Detection Codes (ECC/EDC) from each sector whenever possible. The encoder automatically adjusts to different sector types and automatically skips any headers it encounters. Since the data skipped is nearly impossible to compress with traditional tools, the resulting ECM file will compress far better than the raw CD image.
