[Big Endian] The game crashes after libultraship intro

[Link4Electronics]

Description of the crash:

I compiled the source on a Big Endian system, PowerMac G5 running Debian sid PPC64. I provided the mm.o2r on the same folder as 2sh2.elf, when try to run it, it opens, shows the libultraship intro, and then crashes. It seems to be something realted to the access of the mm.o2r due to the byteswap requierd for Big Endian systems. The thing is, Shipwright works perfect fine on the same system (I attached a screen below)

Screenshots or videos:

Just to verify, did you generate your O2R with the same build you are trying to run?

additionally, did you ensure to generate the 2ship.O2R

Oh hey, thanks for the reply, yes I followed the instructions in BUILDING.md, there's 2ship.o2r and mm.o2r, but I decided to do a clean recompile again just to be sure because I think I maybe messed around with mm.o2r between versions (little and big endian buildings), it'll take a while to finish compiling, will report back when it finishes.
Best regards, Link.

No dice. new compilation with fresh 2ship.o2r and mm.o2r generated.

I suspect that the mm.o2r is being generated or loading with only little endian systems in mind, and then it crashes when loading.

You should try building https://github.com/HarbourMasters/2ship2harkinian-WiiU which has some big endian fixes which haven't been upstreamed yet.

Yay! Progress, kudos!

Had to edit the imconfig.h to make DearImGui render properly

#define IM_COL32_G_SHIFT    16
#define IM_COL32_B_SHIFT    8
#define IM_COL32_A_SHIFT    0
#define IM_COL32_A_MASK     0x000000FF

And is completely muted, no music and SFX, Shipwright plays music.

Best regards,
Link.
