Great to hear !

I am busy with generating the new ini files.
They are almost done, took the whole day to create them.
Curious what comes out of them.
The jakks should appear. (edit : they are already there)

Hey everyone,

I successfully added Konami Handheld, Tiger Handheld and Jakks. Having two problems with Classic Handheld. 1) I can't scrape using either scrapper. Says the platform isn't defined. Even though I used this:

<name>classich</name>
<fullname>Classic Handheld Systems</fullname>
<path>/home/pi/RetroPie/roms/classich</path>
<extension>.mgw .MGW .7z .zip</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ classich %ROM%</command>
<platform>classich</platform>
<theme>classich</theme>

</system>

More importantly, the games won't launch. I copied the artwork into the artwork folder (even though not every rom file had a corresponding artwork file). Below is the verbose log:

And I'm using the following for the emulators.cfg file:

lr-gw = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-gw/gw_libretro.so --config /opt/retropie/configs/classich/retroarch.cfg %ROM%"
mame = "/opt/retropie/emulators/mame/mame %BASENAME%"
mame-autoframeskip = "/opt/retropie/emulators/mame/mame -autoframeskip %BASENAME%"
default = "lr-gw"

Any ideas why this one isn't working? Thank you for your help.

I think it's because.
You have to load Madrigals roms (.mgw) with lr-gw.
Btw. madrigals don't need artwork.

Mame roms from "mame-merged" have to be loaded with mame or lr-mess.
They will run without artwork but with artwork they will look how they should.

Don't mix them up.
(efootb4.zip is a mame rom so you have to load it with mame or lr-mess)

@Folly ahh, thank you Folly. That did the trick! They are now playable. I appreciate the help as always!

Regarding the scrapping problem. Any suggestions there? Hard to find the video snaps manually on those.

Thanks.

Thanks.

Use Folly scipt to install that or Get the files here (for Classic) and put that in your classich rom folder. It should be ok

For more systems, same approach.

@DTEAM Thanks!

@DTEAM Thanks!

@Retrodade

If you select my hyperlink, they are already there + videos
Did you use Folly script?

If yes, @Folly , it’s probably the same overwriting problem than the last time. I will delete and upload the files again on the driver.

Retrodade

@DTEAM WOW ... ok great i got them now ! thanks and ill delete my scrapes above as its not needed. Amazing

Are there ways to speed up the emulation on a game like Let's TV Play Classic- Namco Nostalgia 2? it's in my game and watch plug and play folder and uses Mame. It's rather sloooow.

DTEAM

@duglor
With a Pi 4, if you select Mame autoframeskip basename in the blue menu (when the game load), it will run at fullspeed. On my Pi, it works well.

@DTEAM
Thanks for this tutorial.
I have done all the steps, but didn't manage to get it working.
I also used the script generator and did all the steps.
I have put the roms in the gameandwatch folder, the artwork in the suggested folder
( \bios\mame\artwork )

But it doesn't show up between my other systems in the retropie home menu.
I thought maybe it's because in the etc\emulationstation\es_systems.cfg file
under gameandwatch, -> extension it says .mgw .MGW
So I've added .zip to the mix, but no joy.

Or do I need to add the gameandwatch also here in this file :
/opt/retropie/configs/all/emulationstation\es_systems.cfg

Or is it simply because there's no gamelist under
/opt/retropie/configs/all/emulationstation/gamelists ?

Hopefully you can help me with is.
Probably a simple solution, I guess.
Thanks in advance.

Greetings,
Soxbrother

No. If so, I've never seen it before.
