The RAMOS that never was is available in the GitHub repo:
https://github.com/AmosFactory/AmosTheCreator/releases
recompiled with the new sources and new config file, it no longer has the root folder dependency so it makes a great replacement for existing disks that use RAMOS - old program disk contents can be copied to and run from any location on your harddrive, just replace the RAMOS and RAMOS1_3.Env files...
Greetings 
Now we have a actual homebrew installer for the Vita, are there any plans to recompile PSPUAE as a .vpk? It runs well on the legacy PSP so im thinking it should run ok on the Vita??
I have tried to recompile myself but I fear my brain has gone rusty over the years
