Mighty Mike (a.k.a. Power Pete)

[xeno74]

Hi All,

I was able to compile Pangea's Mighty Mike on MintPPC and Void PPC yesterday. It works but there are wrong colors with the GL renderer.

Maybe an endian issue?

The colors are correct without the GL renderer but the game is slow without it.

Further information about Mighty Mike: https://jorio.itch.io/mightymike

I created a bug report yesterday. Link: Linux PPC: wrong colors with the GL renderer

Cheers,
Christian

Hi All,

Jorio replied to our bug report yesterday.

It looks like __BIG_ENDIAN__ is correctly set, otherwise you wouldn't have been able to get this far into the game.

Try to change GLRender.c:54 to:

#define kFramePixelType GL_UNSIGNED_SHORT_5_6_5_REV

I compiled it with his modification today.

Code: Select all

/home/amigaone/Downloads/MightyMike/src/Drivers/GLRender.c:54: warning: "kFramePixelType" redefined
   54 |  #define kFramePixelType   GL_UNSIGNED_SHORT_5_6_5_REV
      | 
/home/amigaone/Downloads/MightyMike/src/Drivers/GLRender.c:46: note: this is the location of the previous definition
   46 | #define kFramePixelType GL_UNSIGNED_SHORT_5_6_5
      |

Unfortunately it doesn't start.

Output:

Hi All,

Success! Jorio has posted a solution!

Revert to GL_UNSIGNED_SHORT_5_6_5 and try this instead:

Palette.c:241:

Code: Select all

color16 = ((blue >> 3) << 11) | ((green >> 2) << 5) | (red >> 3);

FramebufferFilter.c:53:

Code: Select all

*color = ((bmix8 >> 3) << 11) | ((gmix8 >> 2) << 5) | (rmix8 >> 3);

It works with the correct colors!

Download for Linux PPC 32-bit without AltiVec: MightyMike_3.0.2-linux-powerpc.tar.gz

It works with Void PPC, MintPPC, Fienix, Debian Sid etc.



Cheers,
Christian
