A500 keeps restarting with PiStorm when RTG is enabled.

Okay. Sounds like you haven’t setup the RTG with Picasso96 (P96) properly. To fix this you need delete the Screenmode.prefs file by booting up without startup-system and using Amiga DOS commands. Preferably copy it first then delete.

Reboot the system and it will bring the workbench back into native Amiga mode Screenmode.

Then try again.

The A1200 version can comfortably handle upto 2GB FastRAM. But that’s a 32bit system. I’m guessing the A500 and being a 16BIT system has a lower ceiling limit for RAM.
