Please help in Tokimeki Memorial 2

Hi all !

I`m playing Tokimeki Memorial 2 Substories 2: Leaping School Festival
the game works fine when come to conversations, choosing menu, etc. but the game freezed when playing / ending the mini games (eg. cooking game). i can`t skip the mini game because its part and eventually the heart of this game.
this game is work fine in my friend playstation ( i dont have a ps)
i`m using the latest cvgs and its patch (the latest patch is to support PE2 isn`t it ?)

can you give advice whats wrong ? the cd i`m using is a backup cd (cdr), i try all the way, try using another cd-rom, copying the game into another cd (cd-rw), using the daemon tools.
And the problem is same all time. are cvgs doesn`t support this game yet ? it`s strange because i`m used to playing Tokimeki memorial 2 without any problem, and i think the Substories have same gameplay with its predecessor (except Substories 1 : Dancing Summe Vacation that using the Dance2 Revolution style)

The game doesnt work either in ePSXe.
please help me. i love this game so much ^__^
