To be more specific i would like to play old a5oo games such as Shadow Of The Beast II that i own in original disks and with a1200 its impossible :/

Most old games can be made to work on A1200 and installed to the HD (like SOTB II) with:

The WHD slave writers do the patching so that even games that work only with 68000 processor can be made to work with a 68020 or higher - or AGA. It may be difficult sometimes and the slaves may be improved as bugs get ironed out. Do read the WHDLoad docs!
