It still is RAM! As RAM means random access memory and the color RAM can be accessed randomly. And in the vic-20 programmers reference guide, it says in the memory map "COLOR RAM".

/Anders

It's always said the VIC-20 has 5K of RAM by default... But what about the color RAM? That is 1024 4-bit nibbles... (equal storage amount of 512 bytes). So the Vic-20 actually has 5.5K of RAM internally. Or?

Is it cheating to use the joystick while playing a joystick controlled game?

/Anders

Put in a check somewhere that the button in up. If you don't want the program to delay while holding down the button, then how about this: start: if NOT (buttondown) then b=0 if (buttondown) AND b=0 then switch the things b=1 end if your normal program loop goto start ....or if you have a delay loop...

I don't know if it's the trick you think about, but I just held down fire all the time to prevent me from incomming bombs and briefly released it just after a bomb (to make the game continue).

/Anders

Sometimes when I press fire to switch position of two things, then I don't manage to release fire fast enough and that makes them to switch back again. That is a little anoying... Just a little note if you like to improve the game...

/Anders

I played your game again yesterday, and when you have learned the tricks how to play it, I think it's way too easy!!! I went on to level 150 just to be sure that I would own the all time high score forever!

Cool, Lee! You're a real hardware hacker! So are you loading rom images from the PC directly into the expansion memory then?

/Anders

What is GAL code?

/Anders

If this is a software only running on the PC - emulating a Commodore diskdrive, then I would guess it's no problem at all.

/Anders

Oops, I should have marked 19K and not 16K as the Super Expander cartridge has a 3K built in (and I can use them at the same time)... Anders, I think 8K has precedence over 3K because if I use the SUper Expander with my 16K cartridge, it uses the 16K.... with the commands from super expander... /And...

And there is a .d64 here:

How much expansion RAM do you have for your Vic20? (Only persons who own a REAL vic-20 can answer.)

It works for me. I just wait for a while, and the next part loads by itself...
