omg i must have dl it before buying arc. silly me...
i noticed that you have 5200 files but how do you add 5200 in retroarch or arc? i cant find core or option.
You must add them to Arc Browser. Retroarch - is just a pack of various emulators, and you must download cores for each platform you want to emulate.
Arc Browser is just a frontend.
I use this cores:
GENESIS - Genesis plus gx
GBA - mGBA
NES - Fceumm
SNES - Snes9x
MAME - Fb alpha
PCE - Mednafen PCE fast
PSX - Pcsx rearmed
You can try another cores if you wish, this is the cores from the video preview
Then in Arc Browser you need to add new system, point it to retroarch core (there are huge pack of presets for most popular cores in Arc Browser and you only need to select folder with roms and add rom extensions for each system).
And then you need to scan roms and scrape box art.
Each system step by step.
This is a basic instruction of how to configure Arc Browser: https://www.youtube.com/watch?v=uaoZU2KaAYY
