Maybe if it is simple you or @dml Could write me a routine to do just that.. No worries of his too much hassle as just about had enough of this chaos anyway

Reckon that's doable. Not too complicated. But might have to be a Sunday job, I'm afraid.

There is no real rush. But like I say, I'm not at home on weekends anyway..

Of course relatively soon is always better because in a few days time, I will have totally forgotten what is going on with all this stuff anyway..

Here ya go...

Up/down arrows to scroll through RAM (truecolour mode, so 640 bytes per scanline)

Reset to quit (!) didn't have time for that bit.

I recommend you set PRGFLAGS to not clear ram on startup (or do, if you think thats more helpful). I didn't check what its currently set to.

Yeah, I'm afraid I'm about to sling my hook tonight, but I'll have a think about the best way to do it. My thoughts would be switch to 2-colour mode. Set the video address to the area of interest. Write alternating aa/55 patterns into memory say once every few seconds. Observe. Perhaps provide feedback over serial.

Actually I don't think so - its just a very simple ram 'panning' tool. I think you were suggesting monitoring memory changes over serial and I can't manage that tonight but be my guest!

Holy crap are you Superman or something

Okay will load that up running out of steam tonight myself as well...

Lost me on that one as I don't see any related options to clearing RAM.. Only fast load, running TT RAM, use TT ram..

Also assume you mean it needs to be running in true colour mode ?

Ah I meant fast load - the fast load bit means 'dont waste time clearing ram'. I just forgot what it was called.

The PRG automatically enters TC mode you don't need to config anything.

So I can move garbage up and down the screen. Not sure what is going on now A couple of pixels are twinkling and whatever address its all at.

EDIT: Why does this remind me of the ultimate ripper cartridge somehow

You are scrolling through ram. the garbage is TOS's stuff in RAM.

Twinkling in the very first page of garbage is maybe ok (some interrupts changing variables).

If you scroll past that (downwards to the empty areas, free ram) and see twinkling == bad news.

[EDIT]

I'll run it on my HW Falcon tomorrow (only tried it in Hatari) and see how it looks. I should be able to tell you exactly what to expect then, will maybe take a photo of the twinkly areas.
