@SenorDeCameros said in Some MAME ROMs don´t works. I send log file wirh verbose logging:

which I suppose is the correct one

Not exactly, the recommended one is to choose an emulator then pick the romsets for it, not the other way around. The reason for this is that testing each romsets with each emulators is time-consuming and might force you into using emulators you should probably avoid (decades-old emulators full of bugs and/or missing some nice features).

@stsweeney41 said in Where to put the mame2003 samples files:

This did not work for me. If it is just my install, then I am fine, but may want to mention the other location in the docs, since it is what is mentioned in the info file I mentioned above, and it does work in my case.

The 'other' location from the .info file refers to the BIOS files, not the samples. Same info from our docs is found also in the official core documentation. Note that RetroPie configures the 'system folder' to /home/pi/RetroPie/BIOS/.

If you have reset your RetroArch configuration - using the Reset menu in RetroArch - then the 'system folder' is empty and defaults to the ROM folder, which might be your case.

@jamietuley Distorted audio is a typical symptom of your device being too slow to emulate a game, which might happen if your device is underpowered for some reason (bad power supply, too many connected devices, ...), resulting in your cpu being underclocked. Most of the time, it's simply that your device is too slow though, and tbh i'm not convinced a pi3 can handle vector games at a high resolution.

@dankcushions You absolute legend! That has resolved my problem. Many, many thanks!

Good, because that was going to be my next question anyway. So this will fix two birds with one stone.

However, is asking where to "source" these audio samples in the same boat as asking how to get/where to get ROMs to download?

UPDATE:

Never mind, I found them and now things are all good. Thanks!

@AkatoshTheGreat also it is fixable in mame via mames menus, but if you want to add other emulators, you will have issues as they expect a different device for each player. Unless you plan only using 1 player.

@Nathan1031982

My rom works with lr-mame and mame.
You just need to find the correct rom.
You can find 0.243 roms in mame-merged.

@mahoneyt944 said in mame2003 default.cfg:

@flagrant99 io games mame2003 will default to using the content directory to save cfgs when a save directory is not specified. You'll need to specify a save directory in retroarch.cfg

savefile_directory

This could be an emulator override

Thank you! Did it.

@barbudreadmon surely 👍. check your PR though, build issues.

@iandaemon The Pi4 does let you rotate in 90 degree increments, though it is nowhere near as simple to do so as on previous generations of Pi. After a couple of days of fiddling, I have Emulation station and Retroarch rotated 90 degrees and (finally) filling the screen. I don’t have the setup menus rotated yet, though. At least on the MAME games I have checked so far, there are no obvious performance issues in doing it.

@mahoneyt944 I was mainly looking at the history of the official driver, which had quite a lot of fixes over the last 15 years. I don't know the status of mame2003+ about those fixes.

Rtype Leo shouldn’t need anything real special to run in Mame. Most of your games will run in the mame 4 all mame2003. But you’ll want to test some of your games in mame libretro 2003 plus. You have access to more cores like mame 2016. Also try Final Burn Neo. I run my games through retroarch on the pc to test them first then place them on my pi 4.

@chuck_g said in Which folder should I add my MAME roms to?:

And advice on the ColecoVision Em?

Install the emulators for ColecoVision ? See https://retropie.org.uk/docs/Colecovision/.

@paul_uk I used to have a spare button assigned to TAB, so it is indeed possible.

From memory, you should have your spare button assigned to something in Retroarch (I believe this can be done from Emulationstation) that won't be used by a lot of games: mine was R3, for example.

Then configure Mame to show the menu upon pressing R3 instead of TAB (which can be done in that very same menu TAB brings up) and your spare button is mapped.

EDIT: just to note, this wasn't with controlblock. All my buttons are connected to an RPi with a Dragonrise usb-encoder, so I don't know if your setup will work the same...

@barbudreadmon said in Analog stick bind recently stopped working in MAME:

@slimbrick there were some changes with that analog-to-digital feature last month, if you recently updated retroarch maybe you'll want to read https://www.libretro.com/index.php/retroarch-1-9-6-released/

Thanks! This will certainly help and the timing correlates very well with when I started having problems.

@lupin it may well be a generic thing that would affect the official retropie image also but they are not supported here because we don't know what has changed under the hood, and also do not want to encourage the distribution of illegal material under the retropie name, etc. the image maker calling it 'official' is particularly egregious...
