I've seen that Gradius 4 is among the working games, but it doesn't seem to work, even though the audit says it's ok. The only issue that MacMAME reports is that the sound is not 100% ok, but then the only thing I see is a black screen and a green number on the upper left corner (and lots of error alerts).

What's wrong with it? Is there anything I can do to make it work? :bemused:

PowerPC CPU games don't work in MacMAME.

D'oh!

So, there's no hope for now? Well, thanks anyway! It's just that I'm a Gradius fan and seeing that game emulated made me kind of happy smile

Not exactly no hope. There is a arcade perfect Playstation 2 port of Gradius IV. Initially it looks like pretty good value for money because you also get Gradius III in the same package. Unfortunately Gradius IV does not hold up, its sort of 'soulless'. Its definitely the lowest point in the series.

If you have access to a PS2 I would suggest passing this over for Gradius V, which is definitely the best game in the series. Utterly fantastic and dirt cheap at the moment too.

Seconding the Gradius V suggestion.

PowerPC CPU games should work fine. Gradius IV works fine on the PC with the interpreter CPU (although at less than 1 FPS on my P4-3.4 GHz) so it should also start up, albeit verrrrrrrrrrrrrrrrry slowly, on Macs. What does the LEDs do? It should start out saying "UP", then "Cx", then "11" for a long time, then "12", "04", "21", and finally graphics will begin appearing at "22", after which the LEDs will turn into a spinning beach ball.

ETA: tried it myself, the PowerPC is definitely running properly, but either the SHARC is busted or I'm not waiting long enough.

That's interesting... it isn't nearly that slow on 64-bit xmame on my Athlon64. It fluctuates between 25% and 75% of full speed, seeming to depend mostly on how many alpha-blending effects are onscreen.

Could this be one driver where x86-64 really is a Magic Fast Box? I wonder how fast it would be with a 64-bit PPC dynarec and a 64-bit version of Aaron's dynamically-compiled Voodoo blitter...

You're not running a debug build. I *only* run debug builds.

Yeah, I realized shortly after posting that that must be the reason. An order of magnitude difference between 32-bit and 64-bit is just too much to hope for.
