The Atari Jaguar Thread

[64bitRuss]

Carl Forhan had an announcement about his Mystery Jag Project #1 and said "is a GO stay tuned"...

I was talking to him about it actually just a few days ago . . . . .

quit holding out Laird!

I'm quite curious as to what this Mystery Project is all about!

Can't wait to find out!

Apologies if this subject has been touched on before, but I've noticed a few of my Jag games have some issues when I play them. Wolfenstein and Sensible Soccer in particular display some odd graphical glitches, even while the game is actually running in quite a playable way. For example, in Wolf 3D certain decorative sprites will be all garbled (you know, the tables and suits of armour dotted about) or the walls will just have black squares where a texture should be, and in Sensi, sometimes the score text is all messed up of the ball won't be visible. Anyone else come across these occurrences? I've tried cleaning the contacts on the carts but it doesn't really help and the Jag is otherwise fine with other games. I've tried both carts in the base unit and also through the Jag CD with similar results. Just thought it was odd. Anyone else seen this type of thing?

I don't think I've encountered those exact problems, but I have had issues with carts not working properly. For me the fix is always the way the cartridge is inserted. Instead of pushing the cart in the slot evenly, try pressing the left or right side first, and then push the other side down. Also having it lifted up a tiny bit instead of being pressed all the way down sometimes helps. It sounds strange but it's worked for me 

[TL]

Never found that problem ever!

Games just seem to either work or red screen.

Corrupted graphics usually is due to the system not being able to read properly from the eproms on the board due to dirty contacts and or bent or corroded cartridge slot pins on the jaguar or bad connection in general to the cart slot pins. The other possibility is the PROMS are corrupted somehow but i dont think this is the case as if they were, the checksum on the cart when booting would give you the red screen of death and it wouldnt pass the checksum.

I suggest cleaning the cart pins nicely and mainly the jaguar cart port. Make sure not to use something that will be too wide or thick causing the pins to be spread out more in the cart slot. A few idiots on other forums will tell you to use a tshirt and credit card which is NOT the way to go....

A quick easy way is to spray some electrical contact cleaner into the cart slot and then use a can of compressed air to blow it out. This should work fairly well but make sure to take the jag apart and the top cage piece off so the motherboard is exposed and make sure EVERYTHING is dried out completely before powering on. Might not be a bad idea to leave in the sun for 10-15 mins... 

Depending on the electrical contact cleaner you get it should literally liquify grease/grime thats on the contacts and make fall right off.

EDIT:  forgot to mention, sometimes the cart slots just get worn out. Best electronics i think sells these cart slot connectors (if you're good at soldering) or you can send it in and have them replace/fix it.

[TrekMD]

That's good advice, Rush.  I'll keep that in mind too.

Yeah I am lucky enough to work in an environment where I have an abundance of electrical cleaning gear and products. Lint free cloth and a bit of contact cleaner is my staple cleaner.

Catch me up here, is Mystery Jag project #1 different than the #1 that was listed on his website since 2001 or something?

If you remember he had 2 listed, the first one turned out to be Total Carnage.

Now I don't know if this is the same one he mentioned back then but I do know what it is!

I know exactly what it is. And I must say, I am happy it is coming out- I had a chance to make it happen for everyone FOR FREE or for cost of parts. But it is what it is. Like I say, just glad it will happen (even for 50-100 bucks each...)
