have my original 64 that i still play my all time fav game Archon on occasionally.  Also have a modded 64c with dual SIDS installed and JiffyDOS to use with my MSSIAH cart for messing around with some freaky beats (wish i had more time for that though)
Also have a 128 that I painted Blue as I got it years ago all beautifully yellowed and retrobright etc. was not in existence then:)

...Even though I can use a C64 emulator running at full speed on the Amiga it lacks something in the sound quality that only the real SID chip can produce...

the Catweasel MK4+ will allow you to use dual SIDS on it to solve your problem Franko...awesome product !
