Thinking they might have been compressed years ago I just tried the old MSDOS version of PKUNZIP (v1.01) which only reports the .ZIP is bad and says to use PKZIPFIX. I tried PKZIPFIX (v1.01) from the same MSDOS archive, but it failed to fix them. It does appear they are corrupt in some way.

Re: Porting spectrum games...

I've uploaded a demo to ftp://ftp.nvg.ntnu.no/incoming/Dizzy.zip I hope people can access it from there? I accidentally uploaded the unzipped version by mistake, this could be deleted as I have uploaded the packed archive now. I don't have permission to delete it myself. The demo is made up from

Re: Porting spectrum games...

All sounds good to me.

Re: Porting spectrum games...

Right, so... framebuffer, 1bit per pixel over/under map, 1bit per tile 8x8 collision map? For a total of 30816 bytes? I'll assume that we're using 64kb for the two screen buffers, 64kb for main game code and music/sound, meaning that the map would ideally break into 96kb segments (for multiloading

Re: Porting spectrum games...

I've been playing with the speccy version on the Sam this morning and I can see now the effect of the sprite being pushed up as you walk into the terrain. I'm not clear on how you're going to fit amiga screen shots into the Sam but I cannot wait to see it! I'll carry on making up a sprite set and

Re: Porting spectrum games...

Console Dizzy is quite clearly tile based for both graphics and collision. If I recall, Dizzy himself is three tiles high and when crossing a tile boundary may walk left or right provided that both of the top two tiles are clear. If he ends up with a tile overlapping his bottom third then he's push

Re: Porting spectrum games...

Yes, Dizzy seems to have near pixel perfect collision, at least for defining the terrain. I thought the bitmap would be 256x192 bits; 0=empty, 1=solid? that would be 6144bytes per screen.

Re: Porting spectrum games...

Thanks Andrew, that sounds perfect! It's up to Thomas to choose between pyz80 and Jam then. I can install whichever and have a go at moving some source around myself.

Re: Porting spectrum games...

I'm definitely up for doing Fantasy World Dizzy, it's also my favourite! I got in trouble several times for phoning the helpline number back in the 0898 days :) Happy memories!

Re: Porting spectrum games...

With foreground, middleground and background you'd be defining graphics which the sprites don't interact with and which they move in front of (that's the background), graphics which the sprites do collide with (the middleground; everything the player actually walks on/against/etc) and graphics whic

Re: Porting spectrum games...

The Nes Dizzy I've seen is the first one, Dizzy the Adventurer. I'd forgotten how good it was, even without an energy bar.. So what size can a single 24kb screen compress down to? Hand drawn screens would be amazing. I've never used 1 or 2 bit tile maps for collision before so it would be great

Re: Porting spectrum games...

Hmmm, gmail shows that my previous email was sent twice. Apologies to all if that happened, I'll check it isn't happening repeatedly and if it is then I'll try to figure out why. I am perfectly happy saying things just once... I think there are three for the Nes, but the other two are just ports o

Re: Porting spectrum games...

The only console version I know is the Nes one and I haven't explored it much.. I'm more familiar with the ST versions but the two are not too far apart graphically. I wouldn't like to have to design as many levels as you could possibly fit in though! ;) I'd like to have a go at re-creating the

Re: Porting spectrum games...

sumed that starting from a spectrum version would be the easiest way to port anything to the Sam. I had the ST graphics from Strider ready and everything! ;) > Dizzy... Arrggh!! I loathe those games! :-)) He's like Morrissey or Marmite it seems, people love him or hate him!
