Thank you so much for your ARCADE 0.195 build. In your last build & this one also I got this error finalizr.XML (11) : error.parsing cheat xpression *temp0 = maincpu.ob@ 8A83* (unknown symbol) It's for FINALIZER - SUPER TRANSFORMATION I had cheats enabled so had to disable cheats. Where do I report this cheat problem ? It's OK I found where to post. Also I can confirm Riding Fight (Ver. 1.00) crashes ARCADE although I did get Riding Fight (Ver. 1.0A) & (Ver. 1.0J) to work once but can't get it to do again even though I cleared the NVRAM. I can also say that I got a build for ARCADE 0.194 off someone else & his version crashed a lot but not always so I think it could be what version of tools there using to compile, but if I find that this ARCADE 0.195 build. is starting to crash on some of my favourite games it's gotta be something different. I'll report back once I have played a huge varity of games but for now just the Riding Fight roms crash. I just checked with another MAME UI & the diffrerence is obvious to me as in that version it is classed as fully working & in ARCADE it's classed as working with problems so I would say Robert has either missed something or he's built it with a version just before the sound was fixed. That's my theory, so hopefully if Robert has got some spare time to make another build then i'm sure he will.
