Outrun also used to have huts in the middle of the road, among other things. Anyway, the 3 heaviest-to-emulate Sega games from the mid 80s are OutRun, AfterBurner, and Galaxy Force II. If only OutRun is slow out of those 3, you have some sort of configuration problem.

Galaxy Force II runs at an acceptable speed for me with auto frame skip (music is the correct speed and frame rate is acceptable) Outrun and Afterburner are another matter, the frame rate has reduced to near the level of a slide show. I would have thought that Galaxy Force II should be the slowest. I threw out all my previous game config files, org.macmame.frontend.plist and org.macmame.macmame.plist. Is there anything I missed that could be causing this?

By the way does anybody know how to stop the caps lock from flashing in Space Harrier? Is this supposed to be emulating an LED on the original hardware?


*Actually on second thoughts, the frame rate in Galaxy Force is not that good but the audio plays correctly*

With regards to Outrun, it's possible there's a problem that's Mac-specific here if there's a huge performance disparity in it compared to a PC if no other similar Sega games display a similar performance disparity (percentage-wise, not absolute frame-rate wise). I'll try to remember to take a look for the next MacMAME update.

Outrun and AB are very similar to each other hardware-wise, while GFII is completely different (the scenery in GFII and the other YBoard games is made entirely out of sprites; there's no dedicated road generator like in the older hardware)

RB, when you say those three games are the heaviest to emulate, do you mean that those three specific games push their respective hardware the hardest, or are you using them as a shorthand for the pre-Xboard/Xboard/Yboard games in general?

Should be both, although Thunder Blade vs AB for worst game on Xboard is a bit of a toss-up.

Outrun, Afterburner and Galaxy Force all stutter (60-80% at frameskip 0) a lot on my 2GHz G5 iMac. If I play them on my PC, which is a 1.6Ghz Athlon, they run _very_ smooth (solid 100% with frameskip 0). Other Sega games run smooth on both machines. Games that are supposed to be slow, do so on both machines. For example, Propeller Cycle runs the same way, about 25%-40% with frameskip 0, on both PC & Mac.

Wow, am I reading that correctly? Outrun doesn't play at full speed on a 2 GIGAHERTZ machine? How can that be possible?

Man, maybe I WON'T get in a hurry to buy a new computer after all. frown

With the old Mame,even on a "slow" G4 1GHz,Outrun was going very very well....other example ? Rod-Land ...same problem.I'll put MacMame 0.77 very near to 0.103,for now :-)

Rod-Land isn't even a Sega game. The only thing it has remotely in common with Outrun is having two 68000s.
