Эмулятор MAME 0.258 instal the new for apple

I noticed that you're having issues with installing and running MAME on your Apple device.

Firstly, I'd like to clarify that the text you provided is talking about a new release of MAME (version 0.261) which might not be relevant to your current issue since you mentioned that you have installed version 0.258.

Regarding your problem with running USA ROM for Cadillacs And Dinosaurs using RetroArch and MAME core 0.258, I would suggest the following troubleshooting steps:

1. Check if the ROM is correct: Ensure that the ROM you're trying to run is a valid and compatible file. You can try downloading the ROM again or checking its integrity.

2. Verify MAME installation: Make sure that MAME is properly installed on your device. Try running another game or checking the MAME logs for any error messages.

3. Check RetroArch settings: Ensure that RetroArch is configured correctly to run MAME core 0.258. You can try resetting RetroArch's configuration or checking the documentation for specific settings.

4. Run MAME in standalone mode: Instead of using RetroArch, try running MAME directly by creating a shortcut to the executable and running it from the command line. This will help you identify if the issue is with RetroArch or MAME itself.

If none of these steps resolve the issue, please provide more details about your setup, including your Apple device model, macOS version, and any error messages you encounter. I'll do my best to assist you in troubleshooting the problem.
