hmm... I don´t think that there r VCD DVD emus

... besides VCDs r MPEG1 and DVDs r MPEG2 ...
so u can´t just rename or change directories ... it needs more work to convert VCDs to DVD...
maybe there r other possibilities to play vcds on ps2... like a program that converts MPEG 1 (VCD) to something PS2 can open...
