Have previous versions of SDLMAME for your platform done this and can you point to a time where it worked on that platform for sure?

The actual machine where I compile and test MAME is a PowerMac G5 DualCore 2.3 GHz with 10.5.8 and the building tools are Xcode 3.1.4 and the latest SDL library version 1.2.14. I will try as soon as possible to re-compile older versions of (SDL)MAME to find where the issue start to occour.

No.07729 MacBoxPPC Tester Aug 23, 2011, 22:40	Ok, I've downloaded some of the older SDLmame binaries from Parodius site and I can tell that version 0.139 (stable) was the latest where something was showing up but I have not tried the intermediate diff versions to follow, for those a re-compile from source is needed. I have to specify that my actual romset is in sync with 0.143 release so the 0.139 binary is running that roms. For TX-1 games they stop on a early diagnostic page where an "Hardware Error Status 17" is reported For BuggyBoy games they go ahead but the road and car graphics are missed Two snapshots are attached to show what is happening on 0.139 From 0.140 on, the graphics for both games is totally missing
