COCO2 Game Editor for the VIC
I borrowed this cool program from Centallica. Here is the disk image.

I have no idea why they called this COCO2. It's an "educational game maker" for the VIC20 with 16K expansion. Because of the name, it's hard to find anything about it on the Web.
When you run the COCO2 program, it just freezes. It gets stuck in a loop at $3D7A, not sure what that code is supposed to be doing.
Using VICE I was able to get the program running by breaking execution and typing G 3D85, which is where it looks like the next chunk of code starts. Maybe one of you 6502 gurus can dig a bit deeper into the problem?
I also have the manual but it's over 100 pages It seems to be reasonably self expanatory though.

Let's see..
16-bit address at $33-34 is set to point to $9111, or 37137 in decimal. By pulling joystick up, the program starts. You may have to pull a couple of times, since the loop keeps writing zero to that register - is it configured as both input and output at the same time?
Code: Select all
3D7A LDA #$00
3D7C TAY
3D7D STA ($33),Y
3D7F LDA ($33),Y
3D81 AND #$04
3D83 BNE $3D7A

It was a dongle. I have an original in a box with the dongle somewhere. Never got to use it since I didn't have RAM expansion though.Schema wrote:There's a little insert sheet that talks about plugging in your "Joystick Adaptor" before powering up the VIC. I assumed they meant joystick, but maybe there was a dongle protection system?
there is always time for "Bonks Adventure" hey Schema i thought Centallica had turn to the Dark side when i saw Coco 2 it being a name of a TRS-80/Tandy product very odd.Centallica wrote:Leif,
Did you try the cassette that came with it as well, to see if that worked?
I guess it's not a double sided floppy with another version on the other side too
Have you been thinking of playing "Bonks" lately, I sure have
