Tutorial: Handheld and Plug & Play systems with MAME

DTEAM

@tpr
Not yet. For Lr-Mess, the approach is currently being tested. I don't know if all controller setups are fine or if speed issues are fixed. To install the games for lr-Mess, follow Folly's approach, see:

For MAME method, if you fallow this tutorial, your systems will be fully fonctionnals and your roms will be also scrape.

@dteam Thanks! Got the Game & Watch games up and running! The tutorial is great! One question. Is there a way to set the frameskip to auto in the .ini or somewhere else so it loads with that config already set to auto?

No, I've try but without success. Maybe @Folly knows.

I think you have to add it in the commandline in /opt/retropie/configs/mame/emulators.cfg :
mame = "/opt/retropie/emulators/mame/mame -autoframeskip %BASENAME%"

Look here for all commandline options :

@folly Thanks! I'll try that!

TPR

@folly Wow! I think that might have worked! Thank you! This is what I have in my emulators.cfg:

mame = "/opt/retropie/emulators/mame/mame -autoframeskip %BASENAME%"

@DTEAM can you check to see if that works for you? I'm still a bit new to using these roms so I'm not 100% sure.

I think, if you press F11 you can see if the autoframeskip is on or not.

TPR

@folly Yep! I just did that! Thank you!

Yes it works !!! but i had to add it for all systems. I will modify the tutorial.---> (new edit: It' done) Thanks @Folly !! To see frameskip It's F10... I think
ex.: emulators.cfg in /opt/retropie/configs.hdmi/jakks

Oh yes, you have seperated them.
Well it's an improvement. ;-)

Indeed F10 will also do.
I think using F10 it will dissapear over some time.
I think using F11 it will stay in the screen and dissapear if you press it again.
Am I correct ?

🤣 ahah 👍🏻 But honestly, It's great. It's so simple and I wasn't able to set It. Thanks again.

Your welcome !

Read your configs in the first post, are you going to improve/edit them later on ?

I think it should be something like this, so you can switch between "with" or "without" (with autoframeskip as default) :

mame = "/opt/retropie/emulators/mame/mame %BASENAME%"
mameafs= "/opt/retropie/emulators/mame/mame -autoframeskip %BASENAME%"
default = "mameafs"

edit :
Perhaps you can also do :
"mame-autoframeskip" in stead of "mameafs".
You have to try if this works, but i think it will.

@folly
Yes good point.
Knowing the problems between Lr-Mess and frameskip = auto via retroarch. Do you think this approach could also work for slow systems like GP32.

If I remember correctly, I already tried something with GP32.
If I could improve it, but it keeps working slow.

I will search the post, it was this post ( to you also I see ) :
https://retropie.org.uk/forum/topic/25576/new-scriptmodules-lr-vice-xvic-gsplus-proper-lr-mess-integration/230

Perhaps we can add the frameskipping. Did you try it manually ?

DTEAM

@folly
Yes, with no succes, but I'll retry It tomorrow.

Are you going to try GP32 in mame ?

Try this options :
-[no]cheat / -[no]c

Activates the cheat menu with autofire options and other tricks from the cheat database, if present.
This also activates additional options on the slider menu for overclocking/underclocking.

So you only have to add it like this, I think :

mame-GP32= "/opt/retropie/emulators/mame/mame -c -autoframeskip %BASENAME%"

If you run the game, go to the slider menu for overclocking/underclocking.

@dteam @Folly Seriously great work, guys! I'm in the middle of downloading all the artwork, images, and gamelists from the repositories you've posted. I cannot thank you enough!

Try to find the overclock option for mame.

Honestly, the easiest way would be to use MESS without Lr (retroarch) to see what happens with auto frameskip and systems performance in general. I don'T know how ~~to get It~~. to install It.
