*SOLVED* [Help Retropie 4.3] Some MAME2003 roms not working after update

MrJordaaany

@gamez-fan No problem. I see if I can compile something up then aye? Again thanks for your help :)

arcadez2003

Aye im sorry about this bigman!! if i'd known adding some missing games to the source would have caused all this hastle i'd never have started

MrJordaaany

@gamez-fan No problem. I'm hoping more people run into the issue though so my findings are backed up.

I only have a small seclection (150 roms or so) running on mame2003 ad about the same for fba-alpha. Every time there is an update to an emulator I test them all again so that's how I find issue.

At this stage it might be easier just to use a fresh 4.3 retropie image which contains the mame2003 version before the changes. Doesn't take too long for me at this stage.

MrJordaaany

@gamez-fan Not having any luck compiling shit from source myself (due to lack of knowledge). I know its something I can crack with persistence, but i think for now (and as said) I will use a fresh 4.3 retropie image.

You plan to do more testing once you have the time? So at some point there will be a fix roll out potentially?

Im looking over my commits for errors there are 90 odd so it will take some time. but if i cant get to the bottom of this then anyone with build
issues will need to petition the custodians of the libretro mame-2003 core to roll it back to the original version

It's outta my hands in that regard!!

@gamez-fan once a libretro build environment is set up the first time, it is very easy to compile libretro cores for testing purposes.

Are you interested in setting up your environment? If you provide your operating system I'm glad to help you get it done quickly and painlessly. I think your project is very important so I'm motivated to help any way I can! :)

Hi if the offer still stands i'd like to take you up on this, i use my ole machine for dev which has the Vista OS

Until this is fixed, I could upload September's core binary so you don't have to extract it from the original image.

Does anyone need it?

MrJordaaany

@matchaman I need it please :)

But then what do I do with it? How do I install mame2003 from the code binary?

Many thanks!

matchaman

There you go: https://www.dropbox.com/s/smbzkl7ccleytth/mame2003_libretro.rar

Extract the mame2003_libretro.so file and then replace it in /opt/retropie/libretrocores/lr-mame2003/ (you must be root)

Cheers!

Edit: link fixed

dankcushions

@matchaman mame2010? i think you have uploaded the wrong mame ;)

MrJordaaany

@matchaman @dankcushions Unless he mistakenly renamed it haha

But yes, is it the mame2010 core?

matchaman

Oops, it's getting late here! hahah

I'll fix that in a minute :)

...aaaand done! Check the link again.

In order to verify the downgrade, while running a ROM, open the RetroArch menu and it should show 'MAME 2003 0.78 cb4826a'

MrJordaaany

@matchaman Thank you. Just replaced it now but no dice still. Anything else I could be missing?

matchaman

Check my previous post. Enter the RA menu while running a ROM (default is hotkey+F1) and at the bottom there should be 'MAME 2003 0.78 cb4826a'

Additionally, make sure that rewind is not enabled. MAME doesn't work well with it. Also if you have any game-specific files created, delete them.

MrJordaaany

@matchaman Yup I can confirm that is the case. Hmm I wonder what else I am missing. The same roms are still crashing, but on a clean 4.3 image they are fine. No other files need to be replaced?

matchaman

It's possible that the games have created save/record files that are incompatible with the (slightly) older core. They are located in your ROMs folder and they usually feature ROM names but not .zip extensions.

romname.fs
romname.hi

^------- typical examples. Also remove any .cfg files of the afore in case they force some unknown option.

MrJordaaany

@matchaman Yup removed all that. Still not working. I just popped in my other sd card with a fresh 4.3 image and some of the problematic roms. They work fine. I can confirm the base 4.3 image is 'MAME 2003 0.78 cb4826a' as well.

What could be the dam problem? It only start happening after I updated Mame2003.

matchaman

That's really strange. I just tried those ROMs and they work fine on my setup, using the core file I shared.

Maybe it has to do with some other update (driver maybe?)...

A real head scratcher this one! :/

MrJordaaany

@matchaman Sure is! Bugging the hell out of me. I have a few more ideas then I will just do a fresh 4.3 install.

matchaman

Try updating runcommand. If it doesn't help, replace the text in /opt/retropie/supplementary/runcommand/runcommand.sh with this (mine which works fine):
