When images are upscaled the way eidos did it, the antialiasing spots can become more prominent, so instead of making the image look smoother, it cuts holes into it... I think that's what you're seeing in the eidos counters...
The original, I'm quite certain, was attached and have darker areas around the curves in order to smooth them out... those areas are the gray blotches between the parts of the numbers in the PC version... that is what I believe.
the PSX version looked like a neon light display. Try using a dark color for the numbers then adding some glow to the center of them.
