GX4000 Install Instructions?

Folly

If you want to run gx4000 with mame or lr-mess you can install it with our project over here :
https://retropie.org.uk/forum/topic/29682/development-of-module-script-generator-for-lr-mess-and-mame-standalone

Follow the instructions of the first post.
Make sure you have installed mame/lr-mess and lr-mame.
Then install the system gx4000.

Get the gx4000.zip of the mame-sl romset and extract them in roms/gx4000.

I just tested, you can use the basename loaders if you want for these *.zip files.
Other loaders with -cart work too with these files.

mame and lr-mess will accept these extensions :

pi@raspberrypi:~ $ /opt/retropie/emulators/mame/mame -listmedia gx4000
SYSTEM           MEDIA NAME       (brief)    IMAGE FILE EXTENSIONS SUPPORTED
---------------- --------------------------- -------------------------------
gx4000           cartridge        (cart)     .bin  .cpr

So mame and lr-mess accept :

.bin (-cart loader)
.cpr (-cart loader)
.zip (zip containing a .bin or .crp) (basename and -cart loader)

@Folly Thank you. I'll try this out!

@Retro-Arcade-Fan Did you have any luck? I found that almost no games ran, BUT it turns out that they all work beautifully if you use the 6128+ emulator with cart option instead.

@JimmyFromTheBay I remember I tried and couldn't figure it out, but that was a few months ago. Thanks for the reminder. I need to try again using the instructions above. I'll let you know.

Is it correct that you used mame/lr-mess system driver cpc6128p instead which uses the amstradcpc roms directory ?
Edit -> Ok, just found your thread which explains it all !

Just tested a few games with cpc6128p system driver.
Just like @JimmyFromTheBay says, that works too.
Remember to extract the games from gx4000.zip (from mame-sl) to ~/RetroPie/roms/amstradcpc/ .

If you have difficulties don't hesitate to ask, we both can help.

@Folly Thank you! I appreciate that. I'll try it later today or tomorrow and let you know how it goes.

Actually strictly speaking I installed the GX4000 as a separate system and copied the line across from one EMULATORS.CFG to the other, but I thought that would only confuse things :D

@JimmyFromTheBay @Folly Alright. I followed the instructions and have installed lr-mess and mame. I have gx4000 installed. I also have it as a separate system in my theme and rom folder because I don't want to upset the amstrad cpc system that already works fine by itself. But the only emulator choice I have when launching is lr-caprice32 (probably because I copied my working amstrad cpc setup to try to get the gx4000 system working). I'm assuming that means I need to edit the emulators.cfg file in the gx4000 folder? You mentioned something about lr-mess-system-cpc6128p-cart? And if so, what should I change it to? Or am I missing another step?

Thanks!

@Retro-Arcade-Fan

I followed the instructions and have installed lr-mess and mame.

OK

I have gx4000 installed.

So you installed it from the add-mamedev-systems part.
gx4000 will still use it's own roms directory /roms/gx4000 .

At this point, first try the games from the gx4000 roms directory.
If you are happy enough then you can stop here.
If not then read further.

I don't want to upset the amstrad cpc system that already works fine

@JimmyFromTheBay described that he uses cpc6128p now which will work better.
If you install cpc6128p from the add-mamedev-systems part the script will detect the system as amstradcpc and use that roms directory and also will install the loader lines for that system.
I will not ruin your old setup with lr-caprice32.
You will be able to switch between emulators.
My advice is to just use the cpc6128p/amstradcpc setup.

~~But if you want to use those cpc6128 loader lines for the gx4000 system you will have to copy them from :~~
~~- /opt/retropie/configs/amstradcpc/emulators.cfg~~
~~to :~~
~~- /opt/retropie/configs/gx4000/emulators.cfg~~

Though it will not be perfect.
If you want it to be perfect you will also have to edit the amstradcpc parts to gx4000 in the loader lines.

UPDATE / update the script to 245.03 -> if you want to use those cpc6128p loader lines for the gx4000 system you can now install it from :
option 13(>EXTRA<) -> option 1 -> option 6

You mentioned something about lr-mess-system-cpc6128p-cart? And if so, what should I change it to? Or am I missing another step?

Your not missing a step, the add-mamedev-systems part will generate that module-script and install it directly afterwards.
So you don't have to do anything.

@Folly @JimmyFromTheBay YES!!!! This worked perfectly. Thank you so much for your time in helping with getting this system up and running. Very much appreciated.
