32bit Big Endian ports

[kas1e]

Hi ! We tried lately to port CroMagRally to big-endian (32bit powerpc in our case) HW, with AmigaOS4 and MorphOS oses, and so far have working binary, etc (and we compile everything with TARGET_RT_BIGENDIAN). So game starts, menu shown:

but once we choose to start a level, we have a warning:

CMR Fatal Alert: Skeleton file has wrong version #

We assume that this is Endian issues there which arise once port to modern platforms were done ? We suspect that those parts can be guilty for:

https://github.com/jorio/Pomme/blob/master/src/Utilities/structpack.h#L52
and
https://github.com/jorio/Pomme/blob/master/src/Utilities/structpack.h#L33

Also, if we do nothing in the menu, then game start to showup some intro probabaly, and died as well with words "ParseBG3DFile: FSRead failed" which we assume also, big-endian errors ?

Any help/suggestions/etc much appreacted, thanks !

Cool project. Incidentally I was recently commissionned to make big-endian builds for another game, so I fixed a bunch of big-endian issues in Pomme (the support library that is also used by CMR).

I've updated CMR to take advantage of these fixes in ccbfc65. Do note that TARGET_RT_BIGENDIAN is now __BIG_ENDIAN__. Let me know if this lets you enter the race.

Omg ! It works ! Thanks a bunch ! Check this out :

So far everything works fine, sound/music, textures, etc, etc. Interesting that speed is VERY good, usually SDL apps are busy looping and 100% cpu loading, but this one looks like master piece of code :) Do you have plans to add big-endian support also to your other games ? I am sure amigaos4 and morphos users will be happy with such quality games !

Awesome!

What's with the echo, though? Is it due to your recording setup, or does it actually sound like this?

Also, the powerups aren't showing up in your video (only their shadow is visible). They're supposed to look like this:

Re: the other games, I've been working on bringing Bugdom and Mighty Mike to PowerPC OS X. I'll let you know when that's ready.

Yeah it was just update of OBS studio, and thus enable by default both desktop and lgp2 recording-device audio, so they both recored and made echo .. I re-recording it with normal sound, check this out:

As for shadows : yeah indeed, only shadows visibly .. strange ..

Btw, is "Otto Matic" portable too after Pomme have big-endian fixes ? I just cheked it on win32, and game pretty cool

EDIT: build OttoMatic with new pomme, and it show me created window and then says "No ADF magic" and nothing else. But then i realise that i didn't use TARGET_RT_BIGENDIAN, so rebuild with this one, and binary runs, swith to fullscreen mode, and when about to draw things, drop at me assertion failed with words : pixelsProceesed + packetLength <= pixelCount. DecompressRLE:42" , which in system/TGA. , so i assume TGA.c need more endian fixes (and we don't have this issue with croMagRally because it didn't use TGA)

[jorio]

@kas1e I just updated Otto Matic, let me know if it works for you. If it doesn't, please open a new issue on Otto Matic's page so it's easier to keep track of what's what.

[kas1e]

Yeah, thanks a lot ! created not topic in OttoMattic tickets.
Btw, we do fix "missing powerups", it was bug in GL4ES (wrapper we use to have opengl on ogles2 hardware). Now all fine
