I made a typo, I meant to say how much RAM the xbox emulator has access to when running on the 360. Do you mean the hacked compatibility files released in 2018? The synopsis says:
Xbe signature checks removed (lets you run unsigned code)
Xbe section hash checks removed (lets u run hacked xbes)
Game region checks removed (region free baby!)
Game media checks removed (play games from your hard drive)
Debug/Devkit xbes supported (run your own xbox1 code)
Attempt to play unsupported games (doesn't mean it will work hehe)
In game HUD support * NEW * (this will let you access the Xbox 360 in-game menu while playing your OG Xbox title!)
Cross/in game voice chat * NEW * (this should let you use voice chat during OG Xbox gameplay, this is untested as I do not use online features myself, this may not work)
I'm trying to get the chihiro games to work with it, but the loader itself throws an error when i try to launch it, and direct booting doesn't really work well on xbox in the first place.
