ok guys first of all sorry for the downloading stuff 'n all...won't happen again
here's what i figured out yesterday: all the games with issues seem to be related to certain settings in EvoX - so i tried it with all the IGRs (In Game Reset) set to off - and WHOAHEY! it worked. well that is true for SoE and KFK i didn't try SC2 or SBP (Super Bubble Pop has the same issue for me). will try today.
i also found out that it's not necessarily the IGR settings, but it might also be related to the other one which name i (stupid) have forgotten now - but it's the one that's needed to stream video from a pc (RAS or something)...i set this to off and the general IGR to on an the stuff still works

so i suggest to play with all the settings until it works. also you should make notes on this for your personal record and maybe share it with the community (US)
talking abouot loading times i remember a method that was applied back in the days of ripping dreamcast games: dummy files.
the thing is that any cd drive can read data faster when the data is physically situated on the outside of the cd (not on the other side, but more to the outer edge of the data side

). so what people did in order to speed up loading times on the dreamcast is this: they created a file of say 300 MB which contained nothing (e.g. only zeros) and was usually called 000dummy.dat and threw it into the same dir in which the game was situated before creating the iso. the game in this case was 400 MB, so in total you had a 700 MB cd fully filled (this is the whole goal: fill the disc entirely and make sure the game data is as far outside as possible), but the game data was more to the outside, because the dummy file was situated in the beginning of the cd (burners always burn from the inner ring to the outer edge of the cd), because it was the first file to be burnt - that's why the name starts with 000

). catchin' my drift here?
unfortunately i cannot try this , because of a temporary lack of a dvd burner, but i would like you to try this method. so if you have a game of 1.5 GB then create a dummy file (there are tools for this or you might also use a movie or something - just rename it...

) of about 2.5 GB - so the total comes to 4 GB (or whatever the max. capacity of your medium is). create the iso and burn it. try and tell us if there was an improvement!
