C64 "Screensaver"

[stolendata]

yes, ladies and gentlemen, this is bound to "save your screens", be they TFTs or CRTs. run this 5 minutes a day at morning, and again at evening, and your screen's longevity will increase manyfold.

POKE YOU SYS 864;656

[phodd]

@traceyrmj2 ?SYNTAX  ERROR

[jjovereats]

@phodd I am the new traceyrmj2, same boy, different name: POKE 899,222:sys899

[phodd]

@jjovereats .. this makes no sense. you're setting 899, which is in the middle of the cassette buffer, to the DEC,X opcode .. but the rest of the buffer is zero, as is the X register location at 781 decimal.. meaning you execute DEC $0000,0 (reduce the value of location 0+0 by one)... the next instruction is also a zero, which is a BRK, which resets the 64 to some degree, including location 0. What was your objective?

[hamstermadness549]

im using an emulator and did exactly what you said, i typed it in correctly and it worked but it showed to question marks. Any help?

[phodd]

@hamstermadness549 - sounds like your emulator either doesn't have a true C64 ROM, the RUN/STOP+Restore isn't working or clearing the screen properly, or you've mistyped the POKE and SYS. Try POKE2,0:SYS2 (press enter) instead of the R/S+Restore (it does effectively the same thing) then try the POKE781,96:SYS58251 shown in the video.

[hamstermadness549]

@phodd alright thanks. ill try it now and if it dosent work ill just PM you.

Who knew The matrix was just a reality running inside a Commodore 64?

[michaelboett173]

try:

POKE1024+(RND(0)*1000),44:

change the 44....

[michaelboett173]

wow.....I'm gonna test it now woth my real c64. is there any way to change the "?" to another sign?

[phodd]

There is... but if I remember correctly, you'd need to copy the BASIC ROM into the underlying RAM and then change the memory location that stores the "?" that is printed in front of all error messages.

I don't remember the exact details now, but I think there's a longer POKE/SYS sequence that'd work in principle, but it probably wouldn't fit onto the one line after the READY prompt... and that's important for the trick to work.

[MauroSciuto]

it does not work with my emulator.

[phodd]

That's strange. The question marks definitely appear on a real '64 and on the version of the VICE emulator I used to make the video.

The behaviour is due to the C64 ROM, so any true emulator with the original ROM image would behave the same way.

The RUN/STOP and RESTORE step is important: It clears the screen so that the READY. prompt is on line 2 and the cursor on line 3 as seen in the video. Without it the question marks don't appear.

[jjovereats]

@phodd If you do PRINT CHR$(147) and put the cursor at the ready prompt, then type it (POKE781,96:sys58251), goes as normal. :-)
