True, sounds reasonable enough.

a) That wouldn't work.Tried it? I'm always willing to play with stuff if there's even the remotest possibility of it working.
b) The cart contains 2 16Mbit Eproms. Not a 27C1001. It's not like they put a tiny eprom in there and chanrged you $40.00.No, but if my way works you won't need a 32Mbit cart. I have nothing against them using a different way but the fact remains that using a BIOS of it is inevitably going to be much cheaper. If it doesn't work I'm fine with buying their solution, but not trying it on the assumption that it'll never work just seems foolish.
So, you won't support the developers with your purchases, but you do want them to GIVE you their source code?Of course I want; Carl said the source was going to be released, and I'd like to play with it. Very simple. As for supporting them (though I'd hardly call B&C developers) I'd love to but I'm restricted in what I spend by my parents - if I buy stuff online I have to go through them which means they vet my every purchase. Which sucks. If I buy stuff in shops they're fine with it, but I can't buy bypass kit in a physical store, can I? I'm pretty much stuck with whatever I can make for myself and what I can get on my parents' occasional whim, so despite my fairly generous allowance I can't do anything with it, which is just stupid. Hence, making stuff for myself is a good thing, and buying stuff online is bad. If I get good grades I'll be pushing for any of the bypass solutions (probably ProtSE) but frankly my chances aren't great, so I was exploring alternatives. In response to which I've had this thread. Lovely.

From what I am told, the Bypass Cart contains a pair of 27C8000 16Mbit Eproms. You forgot to add the cost of the board, the case, and the decal.Nope, a 27c1001 should be plenty big enough. I was planning on compiling the source to run from $E00000 (think that's the right number of 0's) and burn it as a replacement for my BJL BIOS. Should work fine; then again we'll never know until someone tries so I may as well be that someone.
Comparing apples with oranges I guess, but I'd still much rather pay £0.20 than $40, given the restrictions on my expenditure.
If you're going to be so sarcastic about it because you know so much about electronics, then why not just write your own bypass for BJL?Because hardware isn't software, if I may state the obvious. Frankly, my coding isn't good enough to scratch-build something like that, which is why I enquired as to the availability of the source. If it's not available (which I'm not sure about seeing as nobody has actually answered my question yet) then I'll grab some 27c040's and a socketed cart from B&C and make my own; that way I can at least have the versatility to make my own carts of any other rom images I find lying around my HD (Native being the prime example). 27c040's are almost as cheap as 27c1001s if I get them surplus off eBay - there's two auctions currently running with 10 of them for €9, which isn't bad at all, and gives me enough to make two 2MB carts for under the price of one sold commercially. Simple enough maths for me; sorry if that offended in any way.

B&C Computervisions sells a reather nifty little bypass cart and it costs about 1/2 what others do.Ahahahahahaha.
27c1001 EPROM = £0.13 . Electricity used to burn it a few pence.
B&C bypass cart = $40 = about £30.
You would definitely do well to get one because loading code each time you want to boot a CD is quite tedious.Yes it is, but I'm not going to spend £30 on one if I can make my own for under £0.20. I asked if the source had been released, nothing more.

Anybody know anything about Carl releasing the source to JagFreeCD? I seem to recall it was one of the less major selling points, but I'd quite like to play with some CDs I have and I don't have the funds to buy ProtSE (very sadly). Any news would be nice.
(sorry if you've seen this post before, JI2 keeps crashing so I thought I'd try here while it's down yet again)
Cheers,

T-bird, how do you (personally) go about dumping carts? I considered it a while back and thought I could use a large copy loop and a BJL cable but I never felt the need to put it into practice
You could use a chip extender (dip40 -> ribbon cable -> dip40) and an EPROM burner I guess
That how you do it?Stone

Native
After you get bored with that (believe me you will, it's only one level and no sound
) try JagTetris (re-download it, the version included on the chip hasn't got the funky music). That goes for PacMania and Painter too. Slam Racer's good for a laugh, though you need a 60Hz Jag for it to work properly iirc. There's a great firedemo I found somewhere, I think it's in one of the old BJL archives, so have a look. Very cool; I might even turn it into a BIOS if I can be bothered one day Beats the Jaguar logo anyhow Stone

Didn't notice this thread, I haven't checked this board in...too long
Just some stuff I thought I'd share. Firstly, if you have a socketed BJL setup you can make yourself a Stubbed Jag - burn yourself a copy of the Nov '94 (blue) BIOS onto a 27c010 or 27c1001 and slap it into your socket, then use a desoldering pump or desoldering braid to remove the solder from the holes for the 10-pin pin header you may have noticed in the lower-right corner of your Jag PCB
Fill this with a 10-pin header, make yourself a female-to-female cable (remembering to thread the cable through the back of the Jag before you put the other end on, or you won't be able to close the lid 
) and you can use your Jag with an Alpine. Neat. I don't think you could legitimately call it a Stubbed Jag though.For extra Stone Spangly Modification Points (™) you could plug another socket into your BJL socket, bending pin 30 upwards so it didn't connect. Solder that pin to the center pole of a SPDT switch and the ends to 5V/0V, then burn a 27c020 (or a 29f020, same thing but electrically erasable) with both BIOS images (one in the first 128KB and the other in the last 128KB). Then you can flick the switch to select your BIOS
Normally when you start up a developer Jaguar with an Alpine in it, the stub code is loaded in the $800000 - $801FFF region (doesn't use all that memory). If the Alpine is write protected, the stub then runs from EPROM in the $E00000 and above region of memory.This means you can compile code with start address $E00000 and have it work if you burn it to a suitable EPROM and put it in your Jaguar's BIOS socket. You have socketed your BIOS, right?
What I'd like is a dump of the cart-validity-checking BIOS from the Jag Scott (I think it was Scott, coulda been T-Bird) sold on eBay a few months back. Could be useful to see if my non-functional carts are actuall broken or just playing up
Is there any purpose to owning a development Jag without an Alpine? Do they run unencrypted carts, for example? Just wondering if I should burn one as the first test of my homebrew EPROM burner (nearly finished, just waiting for some parts and a power supply).
Cheers,
Stone

There is a panther prototype out there somewhere, have a search around and you may find the page about it. IIRC it plays a version of Cybermorph...

I got IWAR, Flashback and NBA Jam for $5 each
No boxes or instructions, but carts are mint and work perfectly, natch.
Personally I like IWAR a lot - it's kinda like what Hover Strike CD (all I know, don't have the cart one) could have been with a little less of the excessive t-mapping. Only if you pick a fast ship though...seems far too slow otherwise
Flashback I like (nearly completed on the Genesis, forgot to flick switch at start of last level [afaik...], at end of level got pissed off and never played again). The gfx are definitely nicer than on the Genesis (not just my SCART cable vs my PC monitor, he's wearing a red shirt that wasn't in the Genesis version, and all looks a *little* higher-res). Makes sense since they'd have had to recode the whole gfx engine (they could keep /recompile the 68K logic without too much difficulty I assume) and it's nice that they took the effort to do more than a straight port. Now I've forgotten how to do all the puzzles...I do remember hating the 'run to middle of nuclear reactor and turn it off before it melts down' mission in the city though (arrrrgh and spooge! run! run! run!) - all good wholesome fun.
NBA Jam didn't strike me with it's brilliance, probably because I suck at it, and I haven't played 4-player TT'ed yet. Maybe it'll improve as the players increase. Hope so. It also seems not to like my JagCD (won't boot when the pass-through is used) though no other games do (except IWar which sometimes boots with no music or sound). Hope my JagCD isn't dying on me...

Where would you get new cart connectors from? I'm just curious since I've never seen them around, and I thought they might be fun to play with (make a multicart by switching the cart power lines? other similar stuff).
It's among the various bits of Jaguar I'd quite like to get hold of, along with stuff like spare casings and those chips above R140...call me a cynic but I'm going to blow one up someday (hasn't happened yet... )
Cheers.

You got the red screen, so the AV cable works, at least
Clean everything gold with a Q-tip dipped in rubbing alcohol with the excess wiped off. For non-US people, that's a cotton bud and isopropyl alcohol. Attack any dirty contacts on the cart or cart slot. Test it, and if that doesn't work, check for bent pins in the cart slot (or other crud that may fall in...I once found part of a pencil in the cart slot of a Jag I was modifying for someone!)
Good luck.

I love PDR. Tight gameplay, smooth scrolling, cool gfx effects and I love the music (although not all will, obviously). Think of it as Micro Machines without the huge backgrounds and you'll be close.
Although the skill tests are kinda hard on the higher levels
You'll love it, go fetch.

I love Jaguar controllers...
About PSX controllers; yes, I've had slightly more problems with this (I actually dislodged two tendons from their little grooves in the knuckles playing Fighting Force all day and couldn't use the hand properly for nearly a week, still messed up). Their controllers are obviously not designed for people with non-standard hands/joints and/or hypermobility
BTW, I have a few Jaguar pad -> PC joypad converters for sale if anyone wants them; I'm working on making them more available (and just making more!) but I have 4 or so right now...$8 each, mail me. They use the standard DirectInput stuff so you can use them in DirectX games...play Freespace with them and pretend you have BS and a rare proto VGA adaptor on your Jag

IIRC, all the voice acting and video was done, you've probably all heard about the Trent Reznor fiasco (no in-game music).
The 'teleport' was (again, iirc) a combination of debug code and actual gameplay...I think it was going to play *some* part in the game (moving around cyberspace) but the direct location-to-location movement was for debug.
Crushing is definitely a persistent rumour...knwo knows? Sad though /me wants an Alpine.
Come to think of it, a clear XBOX would be nice too...maybe it'd even incite me to learn DirectX

I looked at the Painter movie, was that actually running on the Jaguar?Yes. There's an older version on the newest version of the BJL ROM, and available for download in some places. I have the new one however
And I like it
Good work Gordon! /me wants centipede

Switchbox? What switchbox?
I know the original grey controllers had short leads but I didn't know about the first production ones.
Gunstar: if you have to pack up your Jag stuff after each time you play (as I did with my first system, my parents hate me leavig stuff all over 'their' part of the house which is why my room is such a tip) then the thickness of the cable is important; if you coil up the cable like me then you really notice; it seems to get weaker each time you do it Probably isn't, but I don't like the feeling of impending doom I have others now anyway, so it doesn't matter, fortunately.

I think there were several models of Jag controllers (the standard ones).True, as has been said many times before here There's 3 production models of the joypad, the differences in which are discussed in an FAQ that I can't currently find
The nastiest (imho) are the first ones (serial starts with B) which have a horribly thin cable (feels really cheap) and black kaypad buttons. There are two models of pad with the grey keypad buttons. And of course procontrollers, grey controllers and that smooth black one that's on JaguDome.

Reminds me of the film Johnny Mnemonic...very cyberpunk...
Seems like the guns guy was reused in Kingpin too
But why shoot him? You're mad, Clint
T's right, the engine looked excellent. I'd have expected the streets to be a lot narrower to explain the lack of human / aerial traffic, and the wild drop at the clipping edge looks a little suspect, but otherwise very cool. I want Go finish it someone

There was Attack of the Mutant Camels, for one
Can't remember the others.
Actually, I saw a PC conversion of AotMC somewhere...have to look it up again for you lot

LMAO Gordon, those most prolific end up with most recognition on this plane
Point taken though; I haven't played with the CD code much at all (just looked through the dev manual section). I don't have any method of running unencrypted CDs right now anyway, so it'll have to wait until I get good enough at coding the beast to re-do JagFree as a BJL-loadable utility (unlikely) or I get ProtSE (likely...wanna play Painter! )
Unless of course you feel like making an executable of the JagFree-type code...?
If not I'll recompile the JagFree source once it's released.
Rgs,

Sorry, but that's only half the truth, a 21-pin SCART does have an RGB-feature, however, it is not standard because the default-signal transmitted by the SCART is the same kind of signal that a common RCA-plug gives You. If You want to use the RGB-function, You must set Your TV to recieve the signal on the RBG-pins (My TV can be set to recieve numerous dfferent channels such as common SCART-input, RGB-signal or YC2/3. This is a setting that I must do for each SCART-input), at least that is how I've come to understand it. Please correct me if I'm wrong.
It's like that on my bigger (more functions) TV, my smaller one (that my dev setup is attached to) does it automatically.
Can't answer your questions though Gunstar, sorry

Caves of Fear is one of the commoner JagCD prototypes - it's the GameFilm technology demo.

Well, I don't really want to replace my JagCD BIOS since last time I took the case off it it took nearly an hour to get it back on again
And it cost a fair bit so I'd rather not deface it too much. My EPROM burner's last parts arrived today so I'll see about finishing that when I get time and then maybe I'll be in more of a position to experiment.
