The goto choice for portable and light-weight RetroArch distro is Lakka, deservedly so, it works very well considering its size and has tons of hardware compatibility. Unfortunately for me I faced some difficulty when trying to use it in a relatively old notebook (low-end Intel i5, 4GB RAM, Intel HD 4000 GPU), it just wouldn’t boot and from a quick read of the debugging methods available… it was a nightmare I was not prepared to endure.
Enter antiX Linux, a light-weight Linux ditro, not nearly as light as Lakka though, but can also be used for more than RetroArch if and when needed. The system takes around 1GB of disk space, plus additional software installation (<1GB), the rest can be used for whatever, including RetroArch itself, ROMs, thumbnails, etc.
I have only tested it on x64 PC architecture, although it is also distributed for 32-bit systems. My tests were carried out in these setups:
- Desktop Intel i7 4770K @3.5GHz, 16GB RAM, NVIDIA GeForce GTX 760 GPU
- Notebook Intel i5 3317U @1.7GHz, 4GB RAM, Intel HD 4000 GPU (Lakka not booting)
Below is a video guide and the instructions used to prepare the portable OS and RetroArch:

Note: This video was captured using a virtual machine since I don’t own dedicated capture hardware, that will explain references to VMware and some occasional lagging. The video is also sped up often times to make the video as short as possible, despite this I managed to fill a full 20 minutes of me d*ckng around, “testing games”.
