wiiu-vc-extractor-2.0.1-win-x64 - A No-Intro Forum Statement from dreimer #67

Open P0W3 opened 6 months ago

P0W3 commented 6 months ago

The “WUP-JBBJ.rpx” file contains an SFC file “MOTHER2 ギーグの逆襲 (Mother 2 - Gyiyg no Gyakushuu) (Mother 2 - Gyiyg Strikes Back).”

dreimer (user of the official No-Intro forum) stated this.

“Didn't wiiu-vc-extractor readd lossy audio? The current SFROM format dumps are restored by using the SFROM file and replace the zeroed out internal tracks with the original ones. This results in good internal checksums or more than enough confirmed modifications from other sources like the Switch Online files where Audio never was removed.”

Here is the SNES/SFC information from Game_Header_v1.
