Amstrad GX4000

Libretro Lakka
#1

I have seen that the Retropie have released an lr-caprice core for retroarch that emulates the Amstrad GX4000. Does anyone think of releasing a similar core for lakka or retroarch? I do not like anything retropie.

#2

If it starts with “lr” it’s already available, AFAIK. We have the cap32 emulator that should work, I think:

#3

I’ve updated to lakka 2.2.2 and the cap32_libretro.info just says this:

display_name = "Amstrad - CPC (Caprice32)"
authors = "Ulrich Doewich|dantoine"
supported_extensions = "dsk|sna|zip|tap|cdt|voc|m3u"
corename = "Caprice32"
manufacturer = "Amstrad"
categories = "Emulator"
systemname = "CPC"
systemid = "cpc"
database = "Amstrad - CPC"
license = "GPLv2"
permissions = ""
display_version = "v4.2.0"
supports_no_game = "true"

Amstrad GX400 does not appear anywhere, and of course, it does not read any rom, cpr or bin. Says: CPC Error loading cart

Hmm, dunno what to tell you, then. The only info I can find suggests that lr-caprice32 is just cap32-libretro: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/libretrocores/lr-caprice32.sh

Thanks, but if I asked if someone from Libretro is going to do something, it’s because I do not want to know anything about Retropie, nor do I use it, nor will I ever use it.

#6

Ok, don’t worry: I’m not asking you to use retropie. My point was that we only have the one cap32 core, and that seems to be what they’re calling “lr-caprice32”, so if they’re able to emulate it through that core, it should work with RetroArch, as well.

It does look like they also have a standalone caprice emulator, so perhaps that’s the one that’s being used for GX4000?

#7

Well, they use the lr-caprice32, I guess they will have a different info file or somewhere in their thousands of captious configurations, duplicated and replicated, they will have made some modification to make it work.

Retropie is a specialist in traveling “directly” from Los Angeles to New York, passing through Seattle.

You need to set the Model to 6128+ in the core options first. From what I read elsewhere not all games may work yet, but I just launched some cartridges (cpr) and they started fine.

Ok, I charge the core, I go to the quick menu, and in options, it tells me that there are no core options available.

#10

Yeah, that’s annoying. You need to start the core first, at least you don’t need to load content in this case.

#11

To me, doing everything you tell me, still does not work with any rom.

#12

Problem solved, had to use the last core nightly.

Thanks to all for the help.

so we could emulate the gx4000 with caprice32 ? thanks

#14

GX4000 games work in libretro-cap32, has @Jamirus said before, you need to set model to 6128+

Here is a compatibility list:

#15

Of course… with the last nightly core and this above settings…

#16

Could you please tell us witch rom format is support because I test gx4000 roms in rar format but no luck, even in bin format it doesn’t work. Is the cpr format is only available ? Thanks

#17

Each cpr occupies 129KB, it is not necessary to compress them.

#18

Ok thanks I found working cpr files
