jonny what kind of modchip do you have, sorry if you already said and i missed it.
i dont have all those games, most the ones i do have all work fine,
i dont have the sprts ones except top spin i have that, and it works fine.
if you cant get THOSE games to work, which work on a modded xbox. meaning font exploit audio exploit, PBL modchip and TSOP,, if YOU cant get them to work then there is something seriously wrong with your xbox. whatever hack or modchip your using.
getting dirty disk errors while playing from the hard drive is a bad thing.
are you using an 80 cunductor IDE cable, ie Ultra100 cable ? if so get rid of it and put the regular back on.
your looking at games that owrk for 99% of the people. now granted there are those who have one or two games that dont work but you have a whole shit load. there is something wrong with your set up.
there are TWO versions of 4979 which one are you using.4979.06 or 4979.67 ?
and have you tried using X2 4977 ? A L L of those games work with 4977..
and i am not accusing you of anything, but. ALL thos egames are ones that if you had downloaded them, are KNOWN to be bad or give troubles, but if you had actually made a REAL copy with dvd2xbox then the problems are not there.
