Jim

Will this show up in the nightly build of Vice?
I haven't seen it yet.

I think I would try dumping the roms and comparing them to known good roms before going to the trouble of replacing them. Here's a BASIC program that'll dump them for you, it takes a while so be patient. :) 1 n$="char":p=128:s=16:gosub6 2 n$="basic":p=192:s=32:gosub6 3 n$="k...

If it's a raw *.bin file (i.e., without load address), I'd expect such a 16K file to be attached to BLK3 and BLK5. That's quite a common case, and would spare us to work with split files for $6000 and $A000. That would be convenient, even better, I think, would be the VRT format . If someone would ...

Well, it's nice and clean and more modern looking.

May take a little getting used to, but I like it!

Thanks Joshua, nice job.

I recently filed a ticket at sourceforge to have a couple bugs fixed in Vice (xvic.exe). The first was that attaching a cartridge rom using the following menu items: 4/8/16KB image at $2000... 4/8/16KB image at $4000... 4/8/16KB image at $6000... did not work correctly if the 2-byte load address was...

One thing you could do is create a program in VICE, using the characters that you're unsure of, then use petcat to convert the prg into text. By doing that I discovered that the PETSCII back-arrow character is converted to a "_" underscore character. Other than that, you might try and stud...

I agree with majikeyric , the EF3 from Jim Brain is your best value right now. The EF3 also has 3 slots for freeze carts such as Retro Reply, Action Replay, Nordic Play or Super Snapshot Besides with Jim you get excellent help if anything should go wrong. I looked on eBay just now and all those EF c...

Strange though, only two cables attached: one going to the datasette, and what is the other one supposed to do? Or is this just a keyboard? Maybe it was similar to the Atari 5200 which had it's PSU attached to the TV switch box and fed power to the unit via the RF cable. Or maybe the unit ran on ba...

Yeah, they're broken alright, send them to me.

No, just kidding, some carts have missing pins 'cause it was cheaper to produce the boards by eliminating pins that aren't needed.

You're very welcome, glad you find it useful.

$3fc - $3ff is unused.
If you havent already done so, go to bombjack and grab a copy of "Mapping the VIC", it's probably the most valuable book you could find for programming the VIC20.

[EDIT: Little slow with that one] lol.

If you look at the screenshot, about 9 lines down you see a "J", which corresponds to address 198 which is the number of characters waiting in the keyboard buffer. Then counting to the right 6 places you see "@K" these two correspond to addresses 204 and 205 which are "CURSO...

Thanks for sharing. Dumping the $6000 ROM from the $A000 socket must have worked then?

I loaded it up in the latest nightly build of WinVice and I don't hear any sounds at all.
Sounds are working in other games though.
I'll have to load it up on real hardware and see.

Awesome! Glad you finally got it working.
Does it have speech, like the ad claims?

It looks like there must be more to it.
Both the warm and cold start vectors are pointing to $6000.

Most of the $A000 ROM appears to be in patterns of data probably graphics or characters.
