This Why i Made a video of the old mame running on a low spec (compared to the new hardware) Amiga 4000 with a old version of mame...
Yes you was true in your old post better less roms compatible but enjoyable and not full compatible but pain slow for our hardware specs...
I Tested more games on the Amiga 4000 and goes great cps too... Eg willow and ghouls n ghost are super ultra mega slow in my Sam 460 and run at 100% on the Amiga 4000 in rtg mode without frame skipping and full audio sincronization.

I asked to a great programmer of our lovely Amiga community to make port of this mame for os 4 ... hope him will find the time to do this porting and make use have fun with Nicola salmoria great project :)

I think that a good choice to port was that:

no?

@Tuxedo

Probably just easier to port the AmigaOS 3 version, I think. :)

@Spirantho

Yes it use Sdl

@Spirantho

the problem was that AmiDog's mame port wasnt a proper port...
I havet the mame menu to choose options and have commandline options to enable frameskip and other options...
So better to port a "real" mame imho...

@all
Not be shocked of this new video
Is Mame 37.b2 running on my Amiga 4000 604e366 mhz AGA
Ghouls n Ghost ... have 2 frame skipped and audio at 22050khz
the game goes at 100% of it real speed

Sam 460 1017 have RadeonHd 6670 last mame Sdl build
Ghouls n Ghost have auto frame skip 10 on 10 frame skipped and goes at 75% of the real game emulation

Amiga 4000 is 20x time faster because the old mame version is more light compared with the new mame builds

Mame amidog was the mame for Msdos/terminal port
that time there isnt a mame gui configuration , there was a free gui for have mame running on windows/linux/mac os and amiga os too.
In the late 90 i was using Nostalgia and that gui was good for all emulators for amiga os 3.x :)

We could probably use the same front end, too! No need to re-write something that works with the OS3 emulation.

@Spirantho

i tested nostalgia not working on Os4 ...

but the old mame gui yes probably because made with standard amiga os gui library and nostalgia if i remember good was using mui ...

No words, your video explains all.

Hope that MAME 37.b2 will really be ported to OS4

It is clear, it doesn´t make any sense to use recent MAME versions on our hardware. Hope someone ports this older MAME also for systems without WarpOS compatibility.

@kyle

Hope too kyle i Think it can be a good software for fun time

There is one person Who can do This port for our hardware, i asked to him thru Pm and if him Will have time Will try to port mame 0.37.x.x to os 4...
I'm sure our hardware is better of a minipc arm based...
with an arm cortex A9 1.6ghz and a m400 video board I can see the mame4droid 37.b5 run ghouls n ghost scaled at full screen and running at 100%

Will see if in the future we can return to play old coin ops on the Amiga os new hw

There is something more to it than just the MAME version, though. MAME is certainly slower than before, but between 0.60 and 0.148, MAME MorphOS has """only""" lost 50% speed.

I remember there was also a small gap between 0.37 and 0.60, but with 0.60, Metalslug (neogeo) would still run at more than 200% speed on a G3@600MHz.

If anybody is interested, i can give old 0.60 sources. It has overlay, sound and a builtin MUI GUI (maybe i only added GUI at 0.69, though, but it would be easy to backport it as well).

In the meantime, here is AmiDog's 0.37b2 compiled for OS4:


http://www.retroreview.com/iang/MAME_0.37b2_OS4.lha

Yes, it has no GUI. It also has other flaws. However, most importantly: It works!

I found that it had corrupt graphics unless I used the CGFX parameter.
For instance:

NewShell:> MAME joust CGFX

You may need a high stack setting, I'm not sure.

Any feedback let me know, but do remember I don't have a huge amount of time to maintain it properly.

If Fab has his code available I may be able to use that too. Most of the problems I had weren't actually in the Amiga code at all - they were coding errors in the main MAME source (invalid tokens using the ## parameter, which presumably worked in an earlier version of GCC).

Naturally if anyone wants my code, just yell.

@Spirantho

GRREEEEEEEEEEEEEEEEEEEEEEEEEAAAAAAAAAAAAAAAAAAAARTTTTTTT!!!!!


now spirantho (ian) you have to upload only to Os4deopot I think all the community will apreciate your job!
About the Gui there is a free gui on the Aminet... Mame gui PPC


THANKS TO MUCH!!!!

If will be translation in italian for a doc i offer my hand about do this :)

GREAT IAN , GREAT community!

SPIRANTHO IT IS GOING GREAT!!!!!!!!!!
Double Dragon 100% FULL SPEED and 100% Audio Sincronization
I use the gui http://aminet.net/misc/emu/mamegui.lha
Just the user need to change the tooltype option in the icon.
No need changing stack ... everything goes perfect.
The only one limitation is this mame dont have the 2x scale gfx ... but if user can adjust their screens resolution wbmode to have 320x240 there isnt problems


GREAT WORK MATE!
Thanks from all us :)

@Spirantho

tested on Amiga 4000 640e366 Double Dragon ... 100% video 100% audio in rtg
on Aga need skip 1 frame same as Amidog version and 100% video and 100% Audio

Simply Great job!

Great, glad it's working so well!
Most thanks go to the original author, I just played with the source files a bit to make them work. :)
