I have some old RISC OS assembly programmes I wrote a few years back and I want to port them to Raspberry Pi.
I ran Mode 28 and wrote output directly to the screen using the memory address where v-ram started -- i.e., I didn't use an SWI call.
Is there anyway to write directly to the screen on the Pi? What is the address and do I need to set a specific mode.
I am currently running Raspbian ... but can switch to RISC OS if that is easier
