ShadowOne333 I took your advice and tested TMNT 2 to see if it's related to the saves I have, so
I disabled MC and started disc 2, started a new game and guess what,
it went to disc 1.
At this point I figured the issue is related to my save file, but why? the games save and load fine so they can't be corrupted, so I looked up complete saves on the internet (TMNT2) to see if that works, what happened? Game freezes at swap disc.
So I thought maybe it has to do with the "multi" MC option,
I decided to
set the game to "individual" instead
and started a new game in disc 2, then
it swapped fine to disc 1.
Finally
I took this new "individual"save and copied my complete save for TMNT2, loaded up the game, picked disc 1, went to the later levels with the other half of the game,
swap disc worked fine.
Went and did that with
the other two games I have,
worked fine (YEAH), so this leaves me with even less games that I use with DM
please hurry up and fix Sonic Adventure and Billy Hatcher
