It turned out to be the mame's make file was defined to be used for X86. (This is what you get for not reading the readme file first... )
I got MAME installed... Thanx again for the great work and guide... (now i need to find some rom to test it... )
abooreal,
Have you managed to make it work on amd64?
From the look of it, yeah, I can see "MAME" on my main screen orbiter.
Now i will put an actual ROM on the system and see if it can find it.
I will keep you updated for my progress~~
note: Yup, I put my favourite rom in there, start linux MCE then select MAME, it's there...
The tab key menu works, control works...
Once again, thnx for the great guide~~
