… I once tried learning how to RE with radare2 but got very frustrated by frequent project file corruption (meaning radare2 could no longer open it). The way these project files work(ed?) in radare2 at the time was that it just saved all the commands you executed, instead of the state. This was brittle, in my experience. I don't have a lot of free time, so I have to leave projects for long periods of time, not being able to restart from a previous checkpoints meant I never actually got further. IIUC, one of the first things Rizin did was focus on saving the actual state, and backwards/forwards-compatibility. This fact alone made me switch to Rizin. To its credit, my 3-year old project file still works! Now for the downside: there is apparently a gap in Windows (32-bit) PE support, causing stack variables to be poorly discovered: https://github.com/rizinorg/rizin/issues/4608 . I tested this on radare2, which does not have this bug. I'm hoping this gets fixed in Rizin at some point, at which point I'll continue my RE adventure. Or maybe I should give an AI reverse engineer a try... …
