Why classic Double Dragon (1 & 2) does no run correctly on Mame?

[Cospefogo]

Gentlemen,

Just for curiosity...

 

Maybe someone has the technical skill t answer my question:

Why classic Double Dragon games (1 & 2) does not run correctly on Mame?

 

Is it a fault of Mame or the games never were dumped correctly?

 

I wonder how nice could be to have a single emulator for these two games

to make them running just like the real arcade.

The best beat'em up games ever!

 

Best regards,

Cospefogo.

play double dragon 1 and 2 on the earlier versions of mame ie mamex-b6 or mameox0.72.

there is some slowdown with the mameox0.84 core i know,but i still think they are very playable on mamedox and mameox128plus.

it is the slowdown you are speaking about right?

 

edit/the slight slowdown at times never put me off,but each to their own.

I do remember at one time I had problems with Double Dragon running very slow and having to use frameskip to compensate.

 

I just tried Double Dragon out for myself in Mame32 FX 0.120 and it plays fine. Try Mame32/Plus/FX or even Fastmame.

 

If it's due to low specs you could try -nojoy or disabling the sound to improve framerate.

 

EDIT : I missed that this was Xbox related. Yep, runs fine in Mamedox.

Hey guys,

 

The only MAME I have on my Xbox is the MAMEoX 128! Plus (latest version)

and both Double Dragons run very slow.

 

On Double Dragon 2 I was able to play deeper into the game,

but Double Dragon 1 is a pain sometimes due to the HEAVY SLOWDOWN.

 

And I really don't dare to turn the music OFF because the

BGM and sound efx of Double Dragon are A MUST!

I love them.

 

Anyway, maybe I should try to run both games on a older MAME for

Xbox to see what happens - but the problem is - As far as I know,

all Mames use the same SAVE FOLDER in the TDATA and UDATA,

right? The directory 4D414D45 (M A M E)...

Platinum uses 4D414D46 (M A M F)

 

Few time ago I was very excited to try PLATINUM V2 and later ARCADES,

but I did notice a LOT of choppy VSYNC problems on many games

who run PERFECT on MAMEoX 128. I even posted a topic about

it but nobody paid attention, so I gave it up.

 

Anyway guys,

Thank you for you replies!

Guys!

 

MAMEox0.72 works unbelievable nice with both Double Dragons!

Oh my God!

 

But still remains the question - How to have both emulators

(Mameox0.72 + MAMEoX128) if they use the SAME save folders?

 

4D414D45!

 

Is there a way to hack/hex-edit MAMEoX0.72 forcing

it to save in another location, like for example 4D414D45072

 

Regards,

Cospefogo.

Yeaaaahhhh!

double dragon,along with the teenage mutant ninja turtles arcade game.2 of the best scrappers to ever grace the arcade.AAAAHHHH the memories.

I own real hardware btw, and slowdown is an issue present on the real hardware with more than 2 enemies onscreen at a time. It's quite noticeable.

 

Slowdown otherwise isn't however, and in MAME is a core issue beyond 0.87. Use an emulator that utilizes any core as old/older than that and you should be fine.

That's a point, good to know.. have the same speed problem with xain sleena (aka soldier of light) from tecmo, i suppose the hardware was quite the same.

It would be great to have a recent mame compiled using a older core!

Is it - perhaps - "feasible"?

 

Because the Mame 0.72b does not permit - for example - custom SKINS.

I would love to have a MAME 072 with custom skin for my Double Dragons!

 

Cheers,
