Hi everybody,

I've been playing on MAME 0.145 this last week or so (I was curious to see how it ran on my Sam440ep!), and I think it's stable enough for other people to have a go at it they want to.

There is a caveat, though - As far as I can see, executables in AmigaOS 4 can't be greater than 32MB as the standard PPC jump function is only 26 bits wide (giving lots of "truncated relocation R_PPC_REL24" errors on linking). Therefore although I have a linked executable of about 200MB with every machine supported, we can't run it because the ELF loader doesn't support it.

So, this being MAME, we can modularise it. This is how come I've been running (for example) Ghouls and Ghosts on my AOS 4 machines.

If people tell what ROMs they want supported, I can add those specifically, until we get to 32MB. So what do people want?

One other thing - MAME is not designed as an emulator for playing games on, it's designed as a preservation tool. The fact you can play the games is a side-effect! Because of this, it's very slow, even slower than previous versions available as it gets more precise.

So who wants a custom MAME build? Any takers?

@Spirantho

i allways wanted to see .chd files working but i dont thnik the hardware is powerfull anuf

@retro

Probably not. But since when has that ever stopped anyone trying? :)

It should work - it's a full build, just without the machine support.
When I get home from work tonight I'll give it a go, along with anyone else's suggestions during the day. Any particular ROM? Something like SFiii3 maybe?

@retro

OK, here is a version with cps3 compiled in. It can only run sfiii3 or sfiii3u so far, but I can compile other cps3 games in easily.

http://www.retroreview.com/iang/mame0145.lha

To run it, make sure you have a roms directory where the executable is, and put sfiii3.zip (without the .CHD file) in there. Then create a directory called "sfiii3" in the rom directory, and copy your chd into there.

Then just run it with "mamecustom sfiii3" or "mamecustom sfiii3u" if you have the US version (more likely).

And let us know how it works. It's ... not fast on my Sam 440ep 600Mhz.... :)

Oh, you'll need to increase the stack ("stack 2048000" I use) before running it (from a shell), and you may want to "setenv SDLMAME_DESKTOPDIM=320x256" or some other smaller resolution, as larger screen sizes slow everything down.

ooooh, yes i am very interested!.

I don't know what's the limit with ELF executables, but I know that at least it's not 32MB - the older 1.06 version's exe (xmame.SDL) is 57.4MB. Also, I would rather compile separate versions for single systems, rather than support only specific games: Steffen Haeuser has in the past released xMame, xNeoMame and xCPMame, I wonder if xMame's configure script still allows this type of selective compilation.

I think it's not so much the executable size per se, more that any jump over 32MB requires a reloc method that isn't supported yet. Maybe MAME changed its structure since then, maybe he knows something I don't. :) I've posted to the Hyperion forum to see if anybody has a solution.

@Toaks

Try downloading it now. I've not got the Cruisin ROM to test with - can you tell me if it works? Ta!

Great, i waited a lot for a news like this !

I have a Sam440 aswell so i fear most games will be very very slow expecially playing them with a recent Mame version or recent games such Street Fighter 3 Third Strike (sfiii3an.zip)

Aniway im going to try this port

I seem to recall that playing that was a nightmare even on a reasonably good PC due to the nature of the games original hardware (a N64 based machine as I remember). It got better with my current spec though

I believe when compiling you can include/exclude machine drivers to limit the compile to a subset of hardware. So you could just ask it to include all NeoGeo hardware, or just the CPM hardware for example and do separate builds in that way. There are versions for the PC made like this mostly for those two hardware types as most people like the SNK/Metal Slug games or the SF series Capcom games and aren't worried about the others.

Wouldnt the reason MAME is so slow on the SAM.. is because its trying to emulate an x86 machine, emulating a 68k, Z80, PPC or SHC machine ?

How many Arcade cabinets used 68k CPUs which should be able to use teh UAE emulation cores?

I cant remember which emulation teh local shop had running, actualy used a 40 Mhz PPC CPU, which should be native code on Sams etc?

What amount of OpenGL coding would be required to handle the custom chipsets on cabinets, MAME.. or how much FPGA?

yeah thats why i asked, i have tried those games on every mame (amiga) and its always so slow that its non playable...

I guess a top of the line windows pc would run it nicely but that won't help me as i haven't got a pc :)

i'll try the game later on when i get back from work. (god damn extended rotations)

To start SF3 I follow your quick guide but without any resolution setting, this is the output i got:

This is the shell output automatically added when Mame exit

Finally, just to add I can be able to crash Mame also starting the exe with a normal double click on its icon (if no game are selected), i think this one must be fixed with an elegant skip

@samo79

You did up the stacksize, yes? I use 2048000 myself (see post 4).

Oh, I tried Cruisin' USA.
It's slow.
I mean REALLY slow.
But then the 600MHz Sam 440ep was never made for this sort of thing. :)

Edit: If you're missing files then you're not using the right archive. Be sure to get the 0.145 ROM for it (emuparadise have it)

Last edited by Spirantho on 02-May-2012 at 02:43 PM.

@Spirantho

Downloaded and tested. Works but its painfull slow (in 640x480 screenmode) A1-XE 800Mhz 512MB.

To make it work:

copy mamecustom in "MAME" drawer
copy sfiii3.zip and sfiii3u.zip in ROMS drawer (70MB)
Create ROMS/sfiii3 drawer and copied there cap-33s-2.chd file (80MB)

From Shell/CLI:
stack 1000000

setenv SDLMAME_DESKTOPDIM=640x480
mamcustom sfiii3

and it loads,t akes some secs. and "works". Will try with 320x256 screenmode to see if there is some speed diff.

Great job!!!!


EDIT1: tried Strider and Ghouls&Ghosts and are more playable, but still slow for "normal" playing :-/


EDIT2:
#mamecustom sfiii3u
Average speed: 13.20% (41 seconds)

@jabirulo

Don't forget the keys F8-F11. They are your friend. :)

F11 shows current speed, F8 and F9 from memory increase and decrease frameskip. I think F10 turns throttling on/off.

It's something like that anyway.

The A1 has very slow memory access so it's not ideal for MAME. The X1000 on the other hand....

@Spirantho

An AmigaOne with a G4@1Ghz is still enough to play CPS and CPS2 games at full speed. Neogeo games as well. But the SDL backend really slows it down by 15-20%.

@Fab

It's true, but SDL has several advantages that go with it:

* it makes life a zillion times easier when you're porting MAME, as you're not really porting - just recompiling.
* It gives you automatic access to fullscreen modes, windowed modes.
* It gives you AHI support
* It gives you AmigaInput support

In other words, there is no way I'd have had time to do it without SDL.... so it's better than nothing is the way I see it.

How are you able to test it, though - do you have an AmigaOS 4 native build of 0.145 already? The last native build I'm aware of is ages old (before the MAME writers got really accurate at the expense of speed). Hence the version on os4depot is much faster than this version, but this version is more accurate and up-to-date.
