Feature Request: Ignore Banner CRC16 Errors and Display Game Title & Icon

[dj5927]

Hello,

I would like to request a feature related to handling NDS ROM files with banner CRC16 checksum errors.

Currently, when a ROM has a corrupted or invalid banner CRC16 checksum, it is displayed simply as "Program Data" instead of showing the actual game title. Additionally, the banner icon is also not loaded.

Some modified or fan-made (hacked) ROMs have broken CRC16 values in their banner data, but the banner text and icon themselves are still intact and readable.

Would it be possible to add an option to ignore the banner CRC16 checksum validation and still display the banner title and icon?

This would greatly improve usability when working with patched or modified ROMs.

Thank you for your consideration!

Hi there,

If the CRC16 checksum is broken, its considered corrupt, this the fault of the ROM hack rather than AKMenu-Next and should be fixed by the ROM hack dev.

Its like this to inform the user their ROM may be corrupt and bypassing the CRC16 could lead to a bunch of other issues or gitches including causing AKMenu-Next to crash if the ROM is actually indeed corrupted (because thats what is used to detect a corrupt or invalid game, the banner and title would be garbage data) so its not a suitable feature to add unfortunately.

안녕하세요,

CRC16 체크섬이 깨진 경우 파일이 손상된 것으로 간주되며, 이는 AKMenu-Next의 문제가 아니라 ROM 해킹 자체의 오류이므로 ROM 해킹 개발자가 수정해야 합니다.

이는 사용자의 ROM이 손상되었을 가능성이 있으며, CRC16 검사를 우회하면 AKMenu-Next가 충돌하는 등 여러 가지 문제가 발생할 수 있음을 알리기 위한 것입니다. (ROM이 실제로 손상된 경우, 배너와 제목이 알아볼 수 없는 데이터로 표시될 수 있기 때문입니다.) 따라서 이 기능을 추가하는 것은 적절하지 않습니다.

On NDS, Twilight Menu, WOOD R4, and PICO all display the correct banner without any issues.
However, only AKMENU shows it as "Program Data" instead of the proper banner.

That’s why I’m making this request.

AKMenu-Next uses the same menu code as Wood R4 so its strange to see it shows fine on Wood R4. Is it the same SD card too?

AKMenu-Next는 Wood R4와 동일한 메뉴 코드를 사용하는데 Wood R4에서 정상적으로 표시되는 것이 이상하네요. SD 카드도 같은 건가요?

I’d like to correct my previous statement.

The same issue occurs on R4 WOOD as well.
I hadn’t used it for a long time, so I was mistaken.

After checking again, I can confirm that the same problem appears on R4 too.

The banner and icon display correctly only on Twilight Menu and the PICO launcher.

Thanks for confirming, if Pico-Loader and Twightmenu++ show it, I will add this to the list of features to add.
