pSX does not support ccd format. However, if you rename the .img file to .bin it will probably work.
Contender - Victory Boxing.bin
Bushido Blade 2.bin
.bin files _require_ a .cue file - there is information in the .cue file that cannot be recovered using just the .bin file - for this reason pSX does not support .bin files without a .cue (I don't want to encourage the silly practice of deleting .cue files).
You may be able to get them working by creating a fake .cue file:
FILE "..name of .bin file" BINARY TRACK 01 MODE2/2352 INDEX 01 00:00:00
This may not work if the .bin file is not mode2/2352, or if the image contains audio tracks. This information would have been contained in the original .cue files.
However, I can play Tekken 3 - NTSC - U , perfectly with pSX. Tekken 3 has these two files Playstation Tekken 3 NTSC USA.bin Playstation Tekken 3 NTSC USA.cue
Awesome! the other two games Bushido Blade 2 and Contender - Victory Boxing run great now. What I did was, I made the cue files as you said and it works great. The sound is great and works much better than ePSXe.
However Cool Boarders - 4 (PAL) still does not work. I renamed the img file to bin as you said and changed the cue file accordingly, now when I open it using pSX , I get this error:
