Why don't these demo guys ever put their stuff together into a really cool game?!? It's cool to see demos, but at the same time demos always feel like they are teasing me with what someone could do on the machine if they put effort into a game. I've been wondering that for years...

OK, so if I understand rightly, you are talking about the hardware being different than what is found in a standard 8k ram expander, is that correct?

Something a little weird on my ultimate expander

Hi all, Recently got an ultimate expander cartridge. I got a rather boring model, considering all the ways they can be built. I decided not to have any cartridge roms, so basically I got a 32k expander with a reset button and a switch that allows one to switch it from expanded to unexpanded without ...

:shock: I understand a little of what you are saying. I *think* I understand the first part. But not enough after I get to the "Either cart has decode logic to use 3k of 8k chip or there is a bank of 3k ram and an 8k chip.". :oops: "it is pretty simple to do" If you would be so k...

A few more sprites on the expanded memory version would be nice too.

I re-sent, but as an afterthought, I downloaded what you already have up on your site and tried in vice and works just fine. You are doing something wrong when you try to run- files are good. Remember to run in an unexpanded machine or with +3k ram only- no more than that. Load "sptim.prg"...

Oh, just caught the edit. The prg files are not corrupted on my 64hdd- work fine on my vic, and on vice, so maybe something with zipping them? I'll e-mail the files without zipping.

OK, I've got the chapter scanned and the files all zipped and ready to go. Only problem- I don't have a place to upload to. Can't find a link at the central commodore repository to upload to or how to contact the owner. If anyone can host it, let me know. The file is big ( over 4.5 MB) beause of the...

ok, thanks for the link. Not exactly a source listing- it would have to be converted to readable code- there is a program with a lot of data statements that pokes something into memory. When run, this does it's magic and then saves a second program to disk (I guess memory contents after poking itsel...

"Did the disk die too?" Nope. As a matter of fact, I aligned my 1541 this past weekend and it's working now. First time I ever did (or tried) that before, so feeling pretty happy about it. I've got a few more 1541s out of alignment in the closet I'm going to have to bring out and align now...

"some games refuse to work well when they detect it" Ahh- I did not know this. I knew some didn't work with my expansion + my super expander with 3k, but I figured it was because the rom in the super expander occupied the same location as the rom in some cartridge games. That's a little we...

internal memory expansion

Hey All, I have purchased and am eagerly awaiting my ultimate expander from Francois. One thing still nagging me- that 3k block of expansion ram not touched by the expander. I came across this some time ago: http://www.cling.gu.se/~cl3polof/vic20expansion/ It describes "piggy backing" ram ...
