Zero5

[Stone]

Has anyone else had trouble making this game run?

 

For me, using both the BJL and Stub94 BIOSes I get some weird results:

 

With JagCD:

Shows JaguarCD bootscreen for a couple of seconds. Then:

 

a) Game boots (shows 'licensed to Atari' logo), then

a1) crashes (weird flickery lines onscreen)

a2) works (never happened, but included for completeness)

 

b) Game doesn't boot.

b1) With JagCD powered, shows 'CD?' logo.

b2) With JagCD unpowered, shows 'Power?' logo.

 

This happens on both BJL and Stub.

 

Without JagCD:

a) on BJL, boots *immediately* to 'Licensed to Atari' screen, then

a1) the flickery lines appear.

a2) it works (only happened once, this )

 

b) On Stub, blackscreens if I press 'B' while powering up (the 'load a commercial cart' instruction). If I press C however (load a flashcart) it reaches the 'Licensed' screen and then dies a flickery death.

 

Anyone have this problem before? Seem to recall someone mentioning the Telegames releases didn't like Jags with certain ranges of serial number...the one I'm testing on has a serial beginning M25.

 

Thing is, from what I saw when it worked it's actually quite a good game (if ridiculously difficult) so I'd like it to work properly

 

All help welcome.

Hello,

 

Has anyone else had trouble making this game run?

For me, using both the BJL and Stub94 BIOSes I get some weird results:

Hmmm...

Well I don't know about the BJL and STUB boot ROMs, but with a

normal Jaguar, it works just fine. It works on my K and M Jaguars

and I never had a single problem with it. I think in the end stories

about machines that it would not run on turned out to be related

to faulty machines, I've not convinced it was related to the chipset.

 

Of course Missile Command 3D still apparently does not run on

some Jaguars, supposedly not on M's, or K's, I can't remember,

but my early K with analog components on-board, my K without

(bought in spring 1994) and my later M machine(s) run it great.

 

Some programs do demand the Atari video initialisation though,

and so can't you just test the normal boot-ROM on those Jags?

 

Cheers,

Richard.

No, because I don't have one The first bank of my quad-BIOS doesn't work correctly (can't see why, either...) so I don't have an original BIOS in that Jag. I'll take the cart with me when I go home for Christmas though, and see if it works unmodified.

 

Thanks

Let me get some things clarified here first, because your post only confuses me. You are talking about the Zero 5 game released on cartidge from Telegames, correct? Your not talking about PhaseZero and just go the names mixed up and you are not talking about some Zero 5 demo or something that can be loaded with BJL, right?

the zero 5 cart works fine on my '93 stub/dev. Jag with the older blue screen. It also works fine on my production Jag&Jagcd. I have had troubles on occasion with it not booting properly due to a bad connection in the cart port somehow though, and it would do a partial bootup like you've described in these instances.

I do know what I'm talking about, honest! Of course I meant the physical Zero5 cart as released by Telegames (as that's what I said ) If you look I referred to loading it with both the Stub and BJL BIOSes, so it would be nice and obvious that I was using the hardware version

 

I'm pretty sure it's not a dead pin in the cart port because it has the same weird effects when plugged into either my Jag or JagCD, and because my Atari Karts works perfectly well (only other cart I have here atm). I think the whole cartspace has to be accessed for the encryption check to pass with the Stub, anyway, which would rule this out, as it boots and shows the first graphic screen.

 

What Richard said did make sense, I'll just hang on until I can test it on another Jag, I think.

I believe I have an M series Jaguar. If I put zero5 in it and turn it on cold it does not work. If I play another game for about five minutes, then put zero5 in it works?

 

Try it, it might work.

 

Note: my jaguar is unmodified.

I also have a Jag that with the JagCD attached, the Jag has to be "warmed up" before Zero 5 will play.

 

If I take off the JagCD, I think Zero 5 works fine pretty much every time.

 

(this is off memory; I do remember I NEED to play something else for a while to get the system going with the JagCD attached)
