SNES Autodetect Issue with Ace o Nerae / Aim for the Ace Fan Translation Patch

Introduction

The Ace o Nerae / Aim for the Ace fan translation patch, available on Romhacking.net, has been reported to cause issues with Bizhawk's autodetection feature. Specifically, when a user attempts to load the patched ROM into Bizhawk, the emulator incorrectly identifies it as a BS-X game and loads the BS-X firmware instead of the intended SNES game. This issue has been observed on Bizhawk 2.1.0 running on Windows 10 Home with an AMD processor.

Summary

The problem arises when a user drags and drops the patched ROM into Bizhawk. The emulator fails to autodetect the game as a SNES title and instead loads the BS-X firmware. This issue is not limited to a specific ROM version, as it has been observed with both a No-Intro verified ROM (CRC32: 6C5F1A18) and a ROM with a corrected checksum (CRC32: 5109E50A). The only known workaround is to change the ROM's extension to something that Bizhawk does not recognize and then select "SNES" as the game type.

Repro

To reproduce the issue, follow these steps:

Patch the ROM: Apply the Ace o Nerae / Aim for the Ace fan translation patch to a No-Intro verified ROM (CRC32: 6C5F1A18) or a ROM with a corrected checksum (CRC32: 5109E50A).
Drag and drop into Bizhawk: Place the patched ROM into the Bizhawk directory and drag and drop it into the emulator.
Observe the autodetection issue: Bizhawk will display a message indicating that it is unable to autodetect the game as a Satellaview base cartridge and will instead fall back to the BS-X cartridge.
BS-X firmware loads instead of ROM: The BS-X firmware will load instead of the intended SNES game.

Host Environment

The issue has been observed on the following host environment:

BizHawk 2.1.0: The affected version of Bizhawk.
Win10 Home: The operating system running on the host machine.
AMD: The processor architecture of the host machine.

Workaround

A known workaround for this issue is to change the ROM's extension to something that Bizhawk does not recognize and then select "SNES" as the game type. This will allow the ROM to load properly.

Possible Causes

While the exact cause of the issue is unknown, it is possible that the problem lies in the ROM's header or similar metadata. However, the user's limited attempts to work around this issue were unsuccessful.

Conclusion

The Ace o Nerae / Aim for the Ace fan translation patch causes an issue with Bizhawk's autodetection feature, leading to the incorrect identification of the game as a BS-X title. A workaround is available, but the exact cause of the issue remains unknown. Further investigation is required to resolve this issue and ensure that Bizhawk can properly autodetect the game as a SNES title.

Future Development

To resolve this issue, the following steps can be taken:

Investigate the ROM's header: Examine the ROM's header and metadata to determine if there are any issues that may be causing the autodetection problem.
Update Bizhawk's autodetection logic: Modify Bizhawk's autodetection logic to better handle fan translation patches and ensure that the game is properly identified as a SNES title.
Provide a fix for the issue: Develop a fix for the issue and release it as an update to Bizhawk.

By following these steps, it is possible to resolve the issue and ensure that Bizhawk can properly autodetect the game as a SNES title.
