RetroArch MAME core gp32 driver. Thought I would answer it instead of dropping unhelpful images.

Hi, I have tried playing this in MAME directly. I have the gp32 driver but the games are extremely lagging/jumpy. Regardless whether you have had this issue or not have you found more success using the MAME core through Retroarch than MAME directly? I tried playing it through Retroarch but Retroarch opens for a split second before closing. My files are zipped .smc and I have Retroarch selected to unzip zipped ROMs. My command line in Retroarch is -L "cores\mame_libretro.dll". The gp32 driver was in my MAME ROM folder, I also tried it in Retroarch's system folder zipped and unzipped just in case that was it but unfortunately no difference.

You obviously haven't set it up correctly. If it's closing then it's a bios issue.

[tallpr24]

i got this working using mame but the games run very choppy

[tallpr24]

[tallpr24]

Can you get it to run smoothly?

[tallpr24]

[JoeViking245]

[tallpr24]

So you're using the standard MAME emulator, not the core in Retroarch? 

I still can't get this to work, either in Retroarch or the regular emulator.

I've got the 5 bios files. I added the "gp32 -memc" like suggested.

Was there anything additional needed?

Your gp32.zip romset should contain the following files:
gp32100k.bin
gp32156k.bin
gp32157e.bin
gp32166m.bin
gp32mfv2.bin
x2c32.jed

While older MAME builds don't require the file x2c32.jed, newer ones (0.208 and onwards I think) do.

@lino11 in the regular MAME emulator, what error message(s) are you getting?  Maybe take a screen shot of that for us.

[tallpr24]

I'm running MAME .0216

the only thing i have in my roms folder in mame is that gp32 bios .zip files

 

[tallpr24]

pm me if you need help finding the bios files, i can direct you ..

[tallpr24]

it runs really bad though, very slow and choppy

[tallpr24]

forgot to tell you, you have to edit your mame.ini to show where your roms are stored, unless you put your roms in the roms folder in mame

[lino11]

Thanks so much for your help, @tallpr24. I was missing the x2c32.jed file in the bios. 

Also, it's important to rename the games to the MAME-preferred list and keep them in .zip format.... 

So Astonishia Story is astonish.zip.... Blue Angelo euro is blueangl.zip and so on...

Is that right?? I couldn't get the games to work otherwise. Although, I can only really get the GP32 system to run to the main menu. Are any games actually loading up? Or what button on the keyboard do you press, I think I pressed #6 and it went to the MP3 screen. And then #3 or maybe #2 (it's slow and laggy) went to a CD screen. Couldn't find the "game" button.

 

And I know this is a basically dead emulated system.... for anyone reading, you're not really gonna be able to play these games yet so it might not be worth your time to troubleshoot if you're at this point. However, if this system does get the tlc it needs to play smoothly, the whole library of games looks pretty cool (and is only like 400mb large). So it'd be nice to have in the archive. 

 

[tallpr24]

thats interesting.  I dint have to rename my roms, it just works.  see my naming format, they are regular full names.

 

 

[lino11]

Yeah, that is odd. I double-checked again, and here's the error message MAME gives me if the games aren't named their respective "software name" -- like the github here has: https://github.com/mamedev/mame/blob/master/hash/gp32.xml

"The selected software is missing one or more required files. Please select a different software."
