BACKENDS: Wii - MYST3: NEW GAME CRASHES

[Hawkfang42]

upon choosing new game on Myst 3: Exile on wii, the game fades to black and then crashes hard. This seems to be a consistent crash, not sure if anything can be done as this may be from the Wii not being powerful enough.

Thanks for reporting thi.

The issue still occurs with a current daily build. It gives a hard Unable to create a renderer! error, when just adding and starting the game with the default settings.

I don't know if this game is meant to be playable on Wii, i.e. is there a bug/limitation, or should this engine just be reworked or disabled.

Would be nice to have this resolved for the 2.9.0 release

[bluegr]

The pixel format used for Myst 3 on Big-Endian systems, such as the Wii, has been fixed in commit a6256a1ea5f0fd4b46f2e5773607c995acf01ad2.

Can you try again with a daily build?

[dwatteau]

On my OSX PPC, Myst 3 appears to run fine with the commit you mention. But on Wii, the November 11th ScummVM 2.9.0git daily build still gives an ERROR: Unable to create a renderer!

[aquadran]

"ERROR: Unable to create a renderer!" that means no renderer is compiled in. WII doesn't have OpenGL 3D support in backend I presume. but also tinygl is not compiled in?

[dwatteau]

Yes, looking at the buildbot logs for Wii, TinyGL appears to be disabled there.

This commit appears to be the reason for it: ​https://github.com/scummvm/scummvm/commit/98b7231047e7065f86be6db808cf69fb66061506

    WII: Disable unsupported features by default
    
    Various crashes can be attributed to these 3 features. The main problem is the lack of RAM and the slow performance of the Wii in connection with these 3 features.

maybe all 3d engines should be disabled altogether on Wii?

[aquadran]

sounds like yes if no any GL

[lephilousophe]

PR ​#6278 should fix it.

[lephilousophe]

As it's merged, the problem should be gone: Myst III will not be built anymore for Wii.
Merged as 0dfc71322afbb0b2d1a66e2c742e2a3e8edac7a7 for master and ab442ec76404856374b13f00afa7b644c9cff876 for branch 2.9.
