in your basic it is filling the screen 3 times:

the print chr$(147) fills the screen with chr$(32) - VERY quickly (slightly quicker than your ASM example in fact!)

and your doing that twice!

@TrollingAround Hi, yes it's a very stupid sample. chr$(147) is the fastest way. I think i wanted to show an sample in BASIC that matches the sample as far as possible that i did in Assembler. I did not however explain that so , yes it's a very stupid and slow sample done in Basic. I would not even do the same sample in Assembler any more too.

@SeanOBriain He loaded the program "UFFE1" from a virtual floppy disk. He prepared the program before recording this video and stored it on a "floppy". On your "floppy disk" there obviously is no program of that name.

What you CAN do to follow through with this example is to type it into your CCS64 just as you read it on the screen here:

"5 PRINT..." and so on. Make sure you hit "Return" after each line and then you can just enter "RUN" at the very end. :-)

Do I need a rom for BASIC for the C64? I tried following your command to load it LOAD "UFFE1",1,8 , but it doesn't find it. :( I'm using the  CCS64 emulator. It's been like 20 year since I used a commodore 64, I can barely remember anything.

@applefreak441 technically no emulators are illegal because they are simply programs designed to replicate the OS of the original device.

[applefreak441]

is it legal to emulate an c 64 ?

@gan9e Oh, you did that prank too? I just made the machine "fake" the power-on screen and flash the cursor. When someone (hopefully someone who didn't know computers, but were curious enough to dare press a key), it sounded like a car alarm gone mad (monitor speaker volume set to max). Surely the shop staff turned it off when that happened -- they had to, since I had disabled the regular Run/Stop + Restore procedure used to "kill" sound-making programs gone awry... :-P

@uhellstr: If you stumble across one of those G4 MacMini's cheap (they are going under $100 on ebay now .. the popular project in the Amiga community is buying those up and installing MorphOS or Amiga OS 4.0 on them since it's based on the 68000 Motorola processor.

@Paperclown No won't sell my Mac. I love OSX to much. I however would like to own a Amiga since i never had the money to buy one when Commodore still existed. They are still great machine. I own several C64's already and use them a couple of times per month just because I like to be able to use the real machines. I have additional hardware to use Flash cards so thats no issue. However for 6502 Assembler i use crosscompiler and and Power64 that works just great for me.

@uhellstr: ? re your comment of bringerofthetruth

if you are bringing up issues with "compatibility" talking about vice or ccs64, then it sounds like your power64 is inferior, because the other two emulators have 99.999% compatibility.. it's just a matter of fluff features and dicking around with screen refresh rates.

sell your mac and upgrade to Commodore Amiga and get a c64 off ebay for $10. Compact Flash cards loaded with games / demos is the way to go.. and you can still use your pc
