Help with game Enhancer

[Bob Mcbob]

hi, i recently got hold of a playstation, it was second hand, and the games that came with it were badly damaged. I managed to make a backup of them and then i went about getting it chipped. My first choice was the chip, but i was convinced by websittes etc that the box(game enhance+) was a worthy alternative. I got one for £10 and it works fine. However, its in black + white, but the games run in color. Isit possible to reflash the rom? iv seen ppl saying to reflash it. The card i bought was called 'code card' and on the actual divice it says 'Game enhancer+' can anybody help me, give me soome info on this?
