Well I have played both versions of this game and I can say that there are obvious differences between the resolution of the pre-rendered backgrounds from both versions, also the music and fmvs sux in pc version, and that´s why there are patchs such as the Aali´s one which let you set the game to a higher res among other things, but wait, most ppl know about this isn´t it? you just need to google it and you will find several threads about this topic, also in this forum.
For any reason the PC version res is much lower and since I got both version of the game and I have already the music patch and higher quality fmvs, I´m now interested in that replacement to get higher quality pre-rendered backgrounds aswell, that´s why I really want to know if that is possible cos I have no clue and I do not know where is allocated the background data in pc version, neither how it works.
