Copcube

Wenlock · April 25, 2009

Finally got copcube working.

The bug was my fault, uppercase instead of lower. No data = no cube!

Hmm,looks like the cpu discovered acid! (-:

So that`s what the copper did in the Amiga. I did know someone who got one of the first that shipped to Melbourne. The genlocker was PAL in - NTSC out though - shame. Amiga users seemed to have trouble beleiving other computers didn`t have a blitter - odd. I think it would have been possible to do effects in the border on a Tandy colour computer, but there`s only two colours to do it with. irq and firq were derived from tv sync, but pal version had two gaps in firq where extra lines were inserted. Oops!

I`ve run a few on a real PS2 now, a half dead one that doesn`t play CDs. It`s hooked up to a 27" tv so demos can look impressive!

Do you hae a link to the original listing for Copcube so I can try it in the emulator Wenlock?

Wenlock · April 25, 2009

Ok,I use http://members.iinet.net.au/~jimshaw/Yabasic/yabres/yabres.html#demos

Scroll down to Shockwave and it`s listed below.

It displays a wavy cube with rolling horizontal colours in th background.

Ah I remember it now.

There are some pretty bad fill bugs on that routine, it runs at full frame rate in the emulator.. As I recall it was kind of slow on a PS2

Just typed blurr the other week, not too bad.
copcube runs better on PS3, sounds like its like the emulator.

Cya!

Nah mate the fill bugs were there on the PS2 as well, I remember them

I`ll have to take ya word forit. I haven`t run it on a PS2 yet. I did see some gaps while I was debugging with a patch to print veriable values on the text screen.

The text screen is massively slow!

Now, where`s that PS2 memory card.

Nice effect I was sure that I went through all the demos on that archive but cant remember this one. Then again there are a lot of demos in that list
