I have a Magic Sword that worked years ago, but after just sitting around for a several years now has what looks kinda of like a sync issue...but not. It doesn't really move around like a sync issue, and what you see in the pic is steady and the game is moving fine behind it (where the blue...
Well..... this is kinda embarrassing. Turns out the issue was due to RAM, but not because of a failing chip. I had noticed after the game being on for a few minutes two of the RAM chips would get hot to the touch. Was getting ready to take them out to replace, only to suddenly notice both...
Double Dragon uses the Wico Leaf switch joysticks (Blue for Hammer and Red for Spike). The Golden Axe's that were in the arcades I used to live at used the standard Bat Microswitch Sticks that were in about every Dynamo HS-1 cabinet at the time.
EDIT: Turns out as soon as I hit submit I...
Thanks for the ideas! I tested the clock freqs this morning and they "seem" to be working correctly and providing the the correct freq to the chips around it. So it looks like its leaning more to bad RAM. Unfortunately I don't have any spare boards sitting around with this type, so I'm...
I have an interesting issues with a Two Crude Dudes (Data East) PCB. After about 10 or so minutes, the graphic and gameplay begin to slow down, but the sound remains fine, and is in sync with the graphics. Eventually the gameplay will get so slow it will just freeze on screen while the music...
Just replaced Q7 and still have the same result, and also tried adjusting the H Hold using the pot on the chassis. The H Hold just kinda "moves" the garbled mess a little, but overall no change.
While changing the H Hold something I did notice was the "black lines" that go across the screen...
**UPDATE: FIXED**
Noticed a hairline crack in the remote board POT for the H-POS. Replaced the 500ohm POT and BOOM...picture. Live and learn I guess.
Back story:
I have a 25" K7000 that died after 25+ years of great service. Flyback had died, so I replaced it with a new one, only to...
I regret selling my EDOT, and Joust. I purchased them from an operator 20 years ago for $300 total. Had to sell them to buy my now wife an engagement ring one year later. I bring it up on a weekly basis.
Understand about the stage repeats. I hate that the only way to get back to the MK3 stages is to make sure you do not uppercut anyone through the floor in Scorpions lair, otherwise you're stuck with the same 4 stages over...and over....and over....and over....
Other than that, I'd still rank...
I played the crap out of Columns on the Genesis. Tetris was just never really my thing. The Music in Columns is one the best parts. The only problem with it, once you get to the fastest speed in the higher levels, it just stays there, so you can practically play the game for hours without...
I'm getting ready to restore a Double Dragon and the only think I don't know how to restore is the RF Shielding (I think that's what it is) in the bottom of the cab around the PCB, Power Supply, etc.
Mine has been ripped up and is missing the lid. I would like to replace it, but have no idea...
