Dreamcast - MMU not supported --> can't run some games?

[unik314r]

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":

Yep, the problem seems to be MMU:

... Forgot to check this list...
Well, I guess I'll have to play TR Chronicles on PSX

Ok thanks a lot

@unik314r

No problem
I hope it works on psx.
You can then edit the compatibility list psx. thank you for your help

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