CFW 5.50 Prometheus-4
For PSP-1000 & PSP-2000v2 Models ONLY!!!!!!!!!!!!!!!!

Install 5.50 Prometheus by simply copying the extracted archive directory to ms0:/PSP/GAME and running it from the XMB, like any other homebrew. The required files to run 6.20-required games will be copied to the appropriate spot and then you’re all set. Call it 5.50 Prometheus or 5.50 GEN-D4.

5.50 GEN-D3 must already installed

i suggest to disable all plugins. use default theme
