Tutorial: Handheld and Plug & Play systems with MAME

@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.

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

Done!

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.

MESS is now a part of MAME.
In the lr- versions, arcade and computers are still somewhat splitted.
Therefor It's not needed to use MESS anymore because it's 1 package now.

Perhaps you can still compile standalone MESS,
but then you have to edit the makefile of the MAME source and compile MESS manually.
Finding out how to, will be difficult, I think.

Edit :
Alle these packages are compiled from the MAME source :

lr-mame
lr-mess
MESS (if still possible)
MAME

@folly
Great. I'll try It with MAME first.

@dteam @Folly Is there a repository to download some of the missing artwork, for example, the overlay for astrocmd.zip - I don't see it on the Google Drive that you linked to, or did I miss it?

Thank you!

It works if I switch %BASENAME% by gp32 !!!!!
But something missing, we can see the introduction logos but the game won't load. May Be wrong Bios location. I'm digging to see where the problem come from.
I tested nes, fmtmarty, gp32, jaguar, supracan.
For FM-Marty, I hope It will fix saves bugs.

@dteam @Folly As I'm going through more of the "classich" roms, I take it there are just some games that don't have overlays? I want to make sure I'm not missing something here.

DTEAM

@tpr
No,It’s normal. Some games have no overlay

TPR

@dteam Thank you!

jaguar works like this:

mame-jaguar= "/opt/retropie/emulators/mame/mame -c -autoframeskip jaguar -cart %ROM%"

fmmarty like this

mame-fmmarty= "/opt/retropie/emulators/mame/mame -c -autoframeskip fmtmarty -ram 96M -cdrm %ROM%"

NES like this:

mame-nes= "/opt/retropie/emulators/mame/mame -c -autoframeskip nes -cart %ROM%"

Gamecom

mame-gamecom= "/opt/retropie/emulators/mame/mame -c -autoframeskip gamecom -cart1 %ROM%"

It works with regular game names !!!! Not just with MAME naming... Awesome!! Nothing to do in mame.ini

It’s scary how It’s simple!

@folly, You could have two emulators (lr-mess and mame/mess) with your script if you want !!!! (-;

Folly

@dteam

WOW, nice. Haha.
Indeed, Now that you say. I was a bit aware of it.
And indeed it's simple if you got the "aha" effect !
I can confirm, I have to look at that some time to implement this it the script, I was aware of it.
Thank you for the suggestion ! ;-).

@dteam

In your earlier post I can't really tell if you got GP32 working or not.

But I had a look. This is the media type you have to load with GP32 :

pi@raspberrypi:~ $ /opt/retropie/emulators/mame/mame -listmedia GP32
SYSTEM           MEDIA NAME       (brief)    IMAGE FILE EXTENSIONS SUPPORTED
---------------- --------------------------- -------------------------------
gp32             memcard          (memc)     .smc

Try this :

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

Explained :

MAME naming works like this :
If it finds the name and checksum in the database (~/BIOS/mame/hash/<system>.xml), if it exists.
Then it knows how to run the game with which type of media and with which system.

In the commands above we tell MAME, what system and media type it has to run.
That's why the gamename doesn't mather anymore.
As you see with jaguar and nes, etc.
That's the theory.

Basically, earlier on, I did the same with Philips CDI in an earlier script.
But with Philips CDI, I could not get it to work anymore.
Now I think it's because of a BIOS change, but I still don't actually know.

Yes GP32 works, but also very slow with autoframeskip and slider overclock 125% .

CD-i also works :

mame-CD-i= "/opt/retropie/emulators/mame/mame -c -autoframeskip cdimono1 -cdrm %ROM%"
