TeamBeam Extraction on GitHub: A Guide to Verifying ROMs

When working with arcade ROMs from TeamBeam's extraction collection, it's essential to ensure their accuracy and completeness. This article provides a comprehensive guide on verifying the integrity of these ROMs using GitHub.

Identifying Misnamed ROMs

If you suspect that a ROM is misnamed, open a ticket on GitHub and provide evidence to support your claim. Before submitting the issue, make sure to review the original file created by TeamBeam and look for any discrepancies. You can also use sources like Arcade Italia to verify the ROM's identity.

Searching for Closed Issues

Before opening a new issue, search for existing ones that may have already addressed the same problem. This can save time and reduce the likelihood of duplicate tickets being opened.

Verifying ROMs with MAME

To ensure the ROMs are playable, test them in MAME 0.139. However, be aware that there is no MAME clone that supports the gfx CRCs provided by TeamBeam. This may be due to Capcom's modifications to remove copyrighted or offensive content.

Targeting Older Versions of MAME

Since the goal of this project is to create a playable ROM rather than a perfect one, it's recommended to target an older version of MAME, such as 0.139 (also known as Mame 2010 in RetroArch). This is because newer versions may not support certain files or have missing dependencies.

Understanding the Differences between SFA2U and SFA2UR1

The ROMs sfa2u and sfa2ur1 are often confused with each other, but they have distinct differences. The main difference lies in their maincpu, which is similar to sz2u.03. To clarify this issue, we can refer to Arcade Italia's sources for SFA2U and SFA2UR1.

In conclusion, verifying the accuracy of arcade ROMs from TeamBeam's extraction collection requires attention to detail and a thorough understanding of MAME versions. By following these guidelines, you can ensure that your ROMs are playable and accurate. Remember to target older versions of MAME when necessary and use sources like Arcade Italia to verify the identity of misnamed ROMs.
