Current MAME core not running games

RetroArch Windows devices
#41

Who knows. When you deleted the Retroarch folder, a bunch of files that are related to Mame functionality were deleted and fresh ones were created. Such as:

  • The core file. Make sure you have the updated current mame core. Delete any other older mame core version to ensure they are not automatically used.

  • The mame.opt file. Thats the core options configuration file, in the config/mame folder. Maybe you changed something there while troubleshooting and needed its default value.

  • The main Retroarch.cfg file in the root/main folder. Same as above.

  • The nvram/ini files of the games. Whenever you run a game, these files are created in the nvram and ini folders, in system/mame. Maybe you already had these from your previous attempts and were corrupted or wrong.

  • The mame default.cfg in saves/mame/cfg folder. This is where the native mame settings are saved via the TAB menu. It shouldn’t cause crashes but you got a fresh one regardless so who knows.

Now, normally, when a cretain game loads but another crashes, it shouldn’t be a mame.opt or retroarch.cfg setting issue. Otherwise no game would load.

When individual games don’t load its usually a rom/core version mismatch. Or a corrupted rom. Or a game override setting you made, which means a certain game is using different retroarch or mame core settings. Rarely, it could be the game specific nvram or ini file.

Well, thanks for the help. I’ll of course be back if anything else comes up. I have to head in to work soon, so I can’t start trimming out the games I don’t want until tomorrow, but if everything is still working afterwards I’ll let you know so that we can close the door on this matter. (and go back to the thread I had already opened about control mapping matters to inquire about something new that is semi-related to what came up there - had to put that on hold to address this matter)

Do your games work in Retroarch on its own ?

If no then your roms are not compatible with the Mame core you are using.

If yes then you have something setup incorrectly in Launchbox and we would need some screenshots to help find the issue. We would need screenshots of your Edit Emulator screen for the Retroarch emulator entry and the Associated Platforms tab of the same window.

I have initiated the process of acquiring the FULL 244 ROMset. I will not remove anything, and I will put it in the MAME folder(instead of the Arcade folder I’ve been using) so any other settings relating to the previous folder arrangement will not interfere.

Parent CPS-3 romsets changed multiple times over the years due to more recent version of their pcb being discovered and dumped. Since MAME “install” their CD (chd) to their simms (nvram) at first boot, it’s indeed entirely possible for some mismatch between both to cause some kind of issue.

Completely forgot about this thread until I got notifications for new postings on it. Oops. :stuck_out_tongue:

Anyhow, I am all set and running. I curated a set of my preferred games out of a non-merged ROMset that lives in my Arcade folder, and also imported a full merged set into the MAME folder to access other stuff I learn about. The full non-merged archive lives on my main PC so I can add to the curated collection as I am reminded of games I forgot about/discover great games I never knew about.

Everything seems to be working fine save for Nintendo Vs system games, which just get stuck on the boot screen. (not that those are a big deal when I have NES on my system!)

I should probably wait until we figure this out before I start trimming the ROMs down to just what I want.. .

Everything’s been figured out as much as it can be for the purposes of this topic. Non-merged ROMset: Trim down as you see fit. Merged ROMset: Keep it all. Everything else is making sure you have the right set for the right version of MAME and figuring out the settings. I’m sure if I dig deep enough I’ll find why the Nintendo Vs system ROMs get stuck, I just haven’t prioritized finding out since I have the NES versions of all those games set to go as well.
