Dear friends. When I started my retirement life, I was pretty much into hobbies. Kuksa glass, wooden spoon, my real profession is like painting. Now, clearing up this huge mess, I started to get involved with the amiga, which has made my life a painter-graphic designer. However, I noticed some things. According to my investigations in this area, Amiga os 3.2.1 is for original hardware, Amiga os 4.1fe is for new amiga clone hardware, but with an emulator. "MorphOs" is for new amiga clone hardware and older hardware with Apple Power processors. Finally, I reviewed Aros 32 and 64. Aros x32 seems to have single processor support. Aros 64 multi-processor support. It seems that Amiga developers always have a weakness. Not focusing on up-to-date hardware and competing seems to have followed no rational path. I want to know this. What applications can be called vital that work on Aros 32 and not on Aros 64? Like emulators. Could you give information. Which version (x86-x64) is currently in active development? Has there been an effort to add multiprocessor support for x32? Thank you in advance for your interest. I can't even imagine what it would be like today if the Amiga had progressed in the right way. stay with love.
