Recently got a PSTV, got it to 3.60, put Retroarch on it for the ultimate goal of PSX. Everything was going smooth until Retroarch decides it doesn't want to run as well as it used to, for no reason whatsoever. Fine, I'll use adrenaline for PSX eboots, get smoother gameplay. Here's where it gets screwed up. I deleted adrenaline from my internal memory, ark too, so I can install on my external usb flash drive. Thing is, ePSP Bubble Installer won't install any bubbles! It only says Save Core File Succeeded ux0:data/psp2core-1498001741-0x0000202471-eboot.bin.psp2dmp and it is classified as a C2-12828-1 Error. So I deleted those psp2core files in the data menu but I STILL cannot install a bubble to inject adrenaline into. Can someone please help me?
