Applications and Porting / Re: MAME for Power

I don't think they are specific drivers because usually MAME when it needs something specific requires it and makes you put it together with the roms. As I told you, they are a whole series of slightly more recent games, from a certain year onwards everyone does it. I've noticed this on all titles that are newer and from the late 90's onwards. I am sure that it is about optimizing the code because you understand that being a bit bigger games, it is already difficult to manage everything and if you start them with a much more modest hardware but based on X86, then the same games, with the same Roma, they go perfect. It's all about MAME on Power!
In my opinion the main problem is that this MAME on Power is simply a transposition from X86, not being written on Power, it does not exploit our processor at all and being a simple transposition, it has all the limits of the case unfortunately ...

Can you be specific about the games you believe are affected? I imagine it's specific drivers rather than the "whole thing."

NO Classic, I'm sure the problem is upstream, both the Debian version and the Ubuntu version have the same identical type of problem, Markr87 confirmed what I said and I'm sure the version of other distros will also have the same problem. The problem will be upstream, the one who deals with the Power version must review some parts in my opinion ...

It depends on if it's bad build options or necessary new code. If it's unoptimized build options, it's your distro. If it's the code or stuff needs to be added, it's upstream ( https://github.com/mamedev/mame ). I don't like the MAME maintainers very much after the debacle when I tried to get a workaround upstreamed awhile ago, but they did at least look at the pull request even if they were jerks about it.

Markr87 yes that's right, what I was telling you too, unfortunately several games a little less old than others, I can say, like, from the late 90s up, they have different functioning problems and that's why in my previous post, I highlighted this thing or that currently our mame does not have optimizations for our processor and therefore it goes badly on slightly more recent games and especially from the late 90s onwards ... Even today the last mame does not have optimizations that improve the situation and if someone does not specifically take our Power version and works on it seriously, we will never have improvements unfortunately ... The code must be optimized for Power ... But nobody knows how to update it and what repository is needed to do it?

Well, the good news is that if there's a Fedora package, then it's buildable. I bet a little LTO and -O3 will go a long way. I'll experiment when I finally migrate my T2.

Hi markr87, sorry but how does Tekken turn to you? I tried the old 2 and it already runs very slow and therefore lacks optimization, just as I said in the previous posts, how does it turn to you? I oh noticed the poor performance on both Tekken 2 and 3 and both Street Fighter 3 ... They all run very poorly compared to the X86 counterpart ...
@MauryG5, I just tried Tekken 2 ver.B and can sadly report it is very slow, no sound and coin buttons not responding.  I didn't spend any time trying to figure out sound and buttons.  I compared it to a cheap i5 system I picked up to run an arcade cabinet I am building.  The i5 runs it at normal speed.

Has anyone been able to get NFL Blitz to work?  Just wondering if it is a no go or more than likely pebcak?

Does it not start? What issue do you see?

I haven't thoroughly tested it (and my ROM set is for an older MAME, so it's possible I'll have some fallout migrating it from my G5 to the POWER9) but basic behaviour seems to be fine.

To be more specific it is NFL Blitz '99.  I am just wanting to see how our Power9's perform.  It loads and gives me the normal cpu, sound, ect., press any key to continue display.  I press a key and get a brief message about how there is no saved state as this would be the first time it has ran.  The screen goes blank and that's all she wrote.  I know it will take longer on the first run but I have let it sit for hours to no avail.  Also of note Esc will not respond.  Requires a reset to get out of it.  My romset and chd files are of the same version as mame.  I get the same behavior with the latter versions of the tekken series as well.

Talos II / Re: Installing the system on a Samsung 980 Pro SSD 1TB

Pocock thanks a lot for suggesting it should work. Cause of problems identified.

I conducted three experiments:

a) new ssd without thermal pad and heatsink -> works fine with AlmaLinux and FreeBSD;
b) new ssd with thermal pad and heatsink -> does not work;
c) old ssd without thermal pad and heatsink -> works fine with AlmaLinux and FreeBSD.

The problem is the thermal pad. I have one with a thickness of 2 mm. It is possible that something is short-circuiting or pressing down.
