Hey all,
I just got a Gauntlet Dark Legacy in a showcase cab.
I cleaned it up, checked the wiring, and then fired it up
The game boots, has video, and technically it plays
However, the gameplay is extremely slow.
If I click on the action button, it takes about 1 to 2 seconds to respond.
Same with the joystick.
I thought it might be the hard drive so i ordered the CF card upgrade but it made no difference.
Any ideas on what I can try?
Thanks
 
I assume you've gone through and exercised all of the diagnostics in the menus?
 
In the diagnostics menus, when you click on a button, do you see the diagnostics recognize it immediately? In other words, is this an input/output issue causing delays?

Also, take a video of the codes it shows from power on through boot and post it here.

And it wouldn't hurt to check the voltage coming from the power supply and especially the voltage that the game board is getting at a ROM. That Jamma connector is famous for getting burnt and starving the boards for power.

Sorry for the delay, I got called into work.
When I go into the diagnostic menus there is no delay at all.
The game shows no errors and makes the single beep that the manual says means all is good

Here is what I found
If I go into the diagnostic menus and then exit the game plays great!
If I just boot the game it is so slow it is unplayable
I have no idea
Thanks

That's okay, I got called into my daughter's wedding, so wasn't here to read your reply anyway. :)

So when you go to the controls test in the diagnostics menus, and you press a button or move the joystick, it registers immediately with no delay?

Have you done the other things that I suggested above?
 
What about the drive read and filesystem tests? What do they show?
 
LOL probably the exact way I learned. :) (fans? what fans?) You really don't want to be trying to find one of those video cards nowadays.
yeah I didn't kill anything, but one night (within the myriad of 40 different things I had to do at once in my family's business) my Sportstation had these radical graphic glitches and that was when I learned the importance of cooling the video card on those games because 3Dfx didn't put fans on those.

Thank God I had the opportunity ~12-13 years ago to buy as many of those as I wanted when a NOS stash turned up. Mine had failed and I bought a NOS replacement and I think 2-3 extras.
 
vintage GPU!!! $500
I have a few questions about this game I just wanted to learn for myself. So it's my understanding some of these late 90's early 2000's games they basically have a regular computer in the cabinet instead of an "arcade pcb". I know a lot about vintage 90's computers from personally owning and repairing several and done many old hdd to cf upgrades to improve reliability and boot speed. My first question is does this game run on a proprietary os locked to this computer or can it be run on any old system assuming it has the right specs? How often do you see these gpus failing in these games because I almost never see it on regular desktops? Can a newer computer run this game and be put into the cabinet?

This isn't that kind of game. it runs with arcade boards using JAMMA, and the 3rd board is the graphics card. there is no computer per se inside the cabinet.

The graphics boards often fail because they need external fans blowing on them to survive, and often times they are not present.

Thank you for educating me on that, honestly didn't even know there was something in between Jamma pcbs and computers. So for this game I'm assuming that gpu would be extremely difficult to source. Now do my previous questions apply to other games that do use computers?
 
this is a three board set. there is an I/O board, a graphics card, and a CPU card. One of the boards has the JAMMA connector on it.

it's tough to find NOS graphics cards for it, yes. They are rare and expensive. There are some vintage computer graphics cards that can be used in a pinch.

I couldn't say about other games.
