Re: Super Carling The Spider (C64)

Anything short of Mayhem in Monsterland 2 isn't going to push the C64 so I wouldn't beat yourself up too much over that. CTS is a great little game and I'm glad to see it get a bit more recognition. Thanks! Your support of the original game over the years has been appreciated a lot. :) Super Carlin...

Super Carling The Spider (C64)

Hi guys, Not been on here in a while, as it's quite some time since I've done any VIC-20 work, or had a VIC-20 that works :roll: I thought some of you may be interested to know that the Commodore 64 version of Carling The Spider has just been released by Psytronik in the last few days. It's availabl...

Re: memory locations used by disk loading

Having said that, it would be good to have more memory available for code. There's a simple remedy for this: just spend your VIC-20 a RAM expansion. I'm serious. I think that's down to the individual really. I never owned a VIC-20 in its time (it's older than I am) and the one I do own now is prett...

Re: memory locations used by disk loading

Thanks for the extended info Mike. I appreciate I didn't say much about what I was wanting to do or why. I have a machine code game that already uses most of the zero page, and pretty much all of $0200-$02FF as data, and the cassette buffer wherever it is in the $03 page as a variable area. I know B...

Re: memory locations used by disk loading

Thanks Mike :) So nothing is needed in the $0200-$03FF area, I could continue to store some data there?

memory locations used by disk loading

Hey guys, something I was wondering about today. Which memory locations on the unexpanded VIC-20 are needed/affected when using the kernel to load a prg from disk? And does their state going into the load function matter?

Thanks :)

Sorry for leaving it so late in the day :) Here's a download link to a zip containing both the PAL and NTSC versions of the game.

Kweepa that'd be great if you could grab it for your site, thanks :)

Carling The Spider for free

Hi friends, I decided this Christmas would be a good time to release Carling The Spider as a free game. Until now it has only been available through Psytronik (as far as I'm aware :D ) so hopefully it will be a new game for some of you! :) I dont actually have anywhere to host it so anyone that woul...

... expanding memory can feel like a bit of a 'cheat' I'll expand (no pun intended) on what I meant by that. To be honest this doesn't apply to the VIC as much as it would on, say, the C64, where expanding memory was comparatively unusual. And it would apply even less to something like a Sinclair Z...

I don't want to rain on anybody's parade, but the C64 version is in the range of 30-40K (cracked version 157 blocks on Latif, but that one contains docs, loading screen and ten trainers). I know the VIC-20 is much more friendly than the C64 but even a half crude version of Ghostbusters at 1/3 of th...

little OT, but why is unexpanded so important? Back in the day, it was deemed important, but that was short-sighted thinking too. C128 and Amiga suffered terribly for publishers promoting software for the "lowest common denominator" in stock C64 and Amiga 500 configurations. ..what Jeff s...

In fact it could almost be done in BASIC. anything can be done in basic. I suppose what I should have said is, it could almost be done justice in BASIC on an unexpanded machine, you couldn't say that of every game. I'd love to see it done unexpanded, but the benefit of say 16k or even 8k expansion ...

WOW! That would be GREAT! It's got to be one in the to-do list. Having a quick think about it, I've got a reasonable amount of what I'd need sprite-code-wise wrapped up in Carling The Spider, it might not be such a huge undertaking. I'll have a think about it as a side project, it would be nice to ...

At the risk of going full circle and making this thread OT again, wouldn't Ghostbusters be a great game for the (possibly unexpanded) VIC-20? I think it's a really fun game and it's made up of some very simple parts. In fact it could almost be done in BASIC.

I'm a games programmer with a small company, mostly for mobile/handheld formats. I don't enjoy it half as much as I enjoy making stuff for the C64/VIC :)
