Snag porting to Linux Gmod #47

Open paulguy opened 2 years ago

paulguy commented 2 years ago

Not sure if there's any interest in a Linux port, but I've made some efforts with getting this to compile and run in the Linux 64 bit gmod, but I seem to have hit an odd problem that I don't understand as it deals with something more Mario-specific, so I don't really know how to narrow down what the cause could be.

So far, both binaries compile and will load in gmod and I can enter the path to my ROM (same MD5 as is on the README), but it'll crash at a point when spawning the Mario in:

Anyway, not sure if you're interested in getting this working. If needed I can explain what I had to do to get things to compile and load (it wasn't much, really), this is beyond my understanding though. I looked at the data pointed to by the displaylist and I can see that it seems to be junk. There're no valid graphics commands as far as I can tell until much further down but it just seems to be incidental nonsense values and the parameters to the command are just junk that causes a extremely out of bounds pointer dereference.

any updates?

Sorry, nothing. I was sick for a while and this was a while ago too and whatever was wrong was well above my head, so I was pretty much stuck anyway.
