PSP 1000 Model Not Launching VSH Menu After Infinity 2.0, 6.61 LME CFW Install

[JK-4799]

I'm using UMDDumper to back up and play my old UMD games off a Micro SD card adapted to Pro Duo Memory Stick. I had a few games, 2 EA titles (Simpsons Game & Need For Speed Carbon), as well as one Sony title (WipeOut Pulse) refuse to boot past the PSP splash screen, would just go black after the splash screen fades and tries to boot further into the ISO files in question. Upon doing some research, I wanted to use the VSH menu to mess with the ISO settings to try and fix the issue for these games. When I press select, buttons stop working but screen acts normal, VSH menu never shows up. As stated, I installed Infinity 2.0 with the 6.61 LME CFW on a white Japanese PSP 1000, followed MrMario's YouTube guide for installation. Any help would be GREATLY appreciated! Would like to get these games running as well that refuse to fully boot, any advice there would help immensely too!
