Stages with the RGB image splitting method show bugged behavior #1326

Describe the bug

This is a historical bug that has existed within mugen that involves Cyblasters automatic stage tool specifically involving one of the methods you could use to split an image for optimization purposes. Historically discovered with Warusaki3's CvS2 characters where their super would cause the background to go completely white. Which Ikemen GO also displays this behavior however upon recent discovery, mugen 1.1b1 displays the correct behavior upon how the super effects should operate. I have also linked the
stage I generated for this.

To Reproduce

1. Download and install any one of Warusaki3's CvS2 characters and said stage
   -Optionally you can use said tool to generate your own the RGB method
2. Go into VS/Training/etc and perform a super with the CvS2 character on the stage.

Expected behavior

Like mugen 1.1b1 the background should not turn white but rather just inversed.
