and that do you think is the website
http://wiki.maemo.org/Sdlmame

in this site are roms database with speed

and if you say other thing more good , you can do it

I have roms that work with N900

Metal Slug Collection
Cadillacs and Dinosaurs

PM me i will send the link

Flandry, what is the name of the command (?) that performs the "shift gears" function in games like Outrun? I know that it is bound to the spacebar on the keyboard, but I would like to remap it and I cannot find it in the list of configurable keys.

BTW I just got a sixaxis controller, and it works very well with MAME on the N900. So thanks, again!

Start the game

1. Press the button for config menu.
2. Select option input (this game).
3. go down to gear shift and change it to whatever you want.

I would say enjoy but mine runs at 18% speed on auto frame skip setting.

Oh, I totally forgot about the ROM-specific config screen. I've never thought to use it since there isn't an easy aceess button ready to go in the N900 version of MAME. Thanks for reminding me.

All the same, shouldn't there be a global key that can be set? I'm thinking of Spy Hunter too, now, and Radmobile, Turbo Outrun,etc. I'd really like to just handle this all at once, instead of per ROM, if I could.

As to framerates, Outrun gets pretty playable at ~ 4-5 frameskip, once you get past the checkered flag bit, you should try it. (But, I kind of like playing these games at a slightly slower clip, it makes 'em easier! %^)

What speed percentage do you get on outrun?

Also in the main menu go to configure general inputs option then select user interface then you can change the button for config menu.

should make things a little easer for you.

Yeah that's the very first thing I did after I read your post, set a key to call up the in-game config. I totally forgot I use that all the time when playing MAME on the PC. You know, out of sight, out of mind.

I get betwen 25-30% speed w Outrun - it gets much more consistent once you pass the checkered flag at the start. Set frameskip at 4 and it's very steady and playable, give it a try (unless you're one of those types that wants things to be "just so", but I don't mind settling - hey, it's OUTRUN on my PHONE!!! 8^)

Also I'll pass on another little trick I just came up with. Since I was quickly running out of buttons to map things to (I have been playing on a GameGripper, and recently started using a Sixaxis - very sweet), I started mapping multiple keys to the same buttons! So, my "insert coin" is also my "start" is also my "pause"! It works very well, and it's kind of fun to come up with button combinations that will be efficient but not conflict with each other. Anyway, just throught I'd share!

25-30% speed.

Do you overclock you're n900?

I know its outrun on my phone which is great and i am a massive fan of outrun (hence my avatar) but my GP2X WIZ set at 533mhz on mame4all 2.5 (build 0.37b5) i get outrun running at 76% speed at 18fps on frameskip 7 very playable and i could overclock up to 830mhz, but my tests on the wiz are up to 600mhz to keep it as close to N900 cpu speed so the comparisons are fair.

There was a conversation a page or so back which explains how this could be achieved.
So my hopes are quite high that the N900 will one day have similar mame performance.

Yep i use six axis and its great with TV out.

Oh yeah, I forgot to say, I OC @ 1GHz!

I don't know why the GP2X could triple the N900's performance, maybe it has something to do with the build of MAME being used?

I actually had my GP2X stolen while travelling and the N900 was its sort-of replacement, if you can believe it! I really liked my GP2X, but I have to say, the N900 surpasses it in so many ways I don't even think about it anymore, Outrun notwithstanding.

Yeah, I didn't even notice your avatar, you're the perfect person to have this conversation with! NB, the GP2X's version of MAME doesn't support Turbo Outrun, but the N900's does! Woot!

OC to 1GB that says it all.

Yeah its all down to the age and version of mame.

new versions - compatibility is high performance on old roms can suffer

older versions - compatibility is high (on roms made up to a certain year mid 90's i think) and performance is excellent. newer roms (late 90's to present day either will not work or run properly)
