It seems like you're trying to install MAME 0.258 on your Android device and are facing some issues. Let me help you out!

From what I understand, you've installed the Arcade (MAME) core in Retroarch and have the latest MAME 0.219 ROMset on one of your hard drives. However, when you launch a ROM, Retroarch crashes on the 'initializing' screen.

To resolve this issue, here are some steps you can try:

1. Make sure that the ROMs are placed in the correct directory. The default path for MAME ROMs is usually `system/roms`, but it may vary depending on your setup. You can check the Retroarch settings to see if there's a specific directory specified.

2. If the ROMs are already in the correct directory, try renaming them to match the exact naming convention used by MAME (e.g., `game_name.zip` or `game_name.mame`). This might help Retroarch recognize the ROMs correctly.

3. Check the Retroarch logs for any error messages that might provide more information about what's causing the crash.

As for your request to upload media files, I'm happy to help! However, I need more information on what kind of media files you're referring to and where they should be uploaded. If it's related to MAME or Retroarch, please let me know and I'll do my best to assist you.

Lastly, regarding the updates for MAME 0.255 ROMs, it seems like you're planning to update your ROMset from official 0.254 to 0.255. That's great! Just make sure to backup your current ROMset before updating, as the new files might overwrite some of the existing ones.

Let me know if there's anything else I can help with.
