De-Dither patch not working with psp EBOOTs #1

When I tried to use the De-Dither patch on a game I downloaded from the psp PS Store (specifically Castlevania Symphony of the Night,) I am able to patch the game with the De-Dither patch and convert it back to an EBOOT.PDP file using PSX2PSP, but when I run it using my psp, all I get is a black screen. Though I can press the home button to get to the settings.

This is out of the scope of this patcher. I have no idea what compression or other changes might be present in eboots. I also have no idea if the PS1 emulator that the PSP uses would even correctly recognize the changes.

No idea if this would work and is not supported by me, but here's what I'd try if it were me: 1.) Take a known working unpatched PS1 ISO you want to use, then use PSX2PSP to convert it and verify it works before being de-dithered. 2.) Run the de-dither patcher on your original ISO, then verify it is working as intended on a real PS1 (or the no$psx emulator. I used that during initial testing). 3.) Run your patched ISO through PSX2PSP and test. If step 1 and 2 succeeded by this fails (or works but still has dither), then I have no idea since it's ultimately an emulator out of my control.
