      Hi,

      I can run a lots of DC games (Crazy Taxi, Marvel vs Capcom 2, Resident Evil Code Veronica etc etc...) but I can't run TOMB RAIDER CHRONICLES.
      I tried 2 different CDIs, same issue: BIOS boots, but game won't load --> I come back directly to ES.

      Here are some logs:

      --> I can see <>MMU Enabled , ONLY SQ remaps work<>
      I could read on the net that it may be the reason why: do you agree?

      Is there any solution to run Tomb Raider Chronicles?

      Thanks a lot!

          Hi,

          it doesnt work.
          I tried the german one (gdi) and also no success.
          In compatibility list it is also marked as "not working":
          https://docs.google.com/spreadsheets/d/1Ep2Lm_nhpXtLp-iZibFXiCZUB7csqWXFzqj8IvvGOJk/edit#gid=1806295408

          Yep, the problem seems to be MMU:

                @abunille Yes it does 🙂
                I've also updated some status for some other games (I'll try to do it as often as possible 🙂 )

                See you!
