  • Quote from gianka: “....I would like to try this procedure: owning an "empty" security cassette, System573 automatically would write the game's eeprom by itself when the game's installed by means of CD for the first time (method to verify) Is this method correct? ” a bit incorrect. for the game to install, it needs CD (original or dump), and install security cassette. later version (afair, from ddr5 up), install and game security cart have become one cart, and they used pic chip for that. for ea…

    Quote from jimmerd: “Hi Dion, Do you remember if on the image you have write access to the PC game files or were they protected? Was it a standard usb or flash card that could be read in another PC? I know somebody who has the 2012 setup and noticed when playing it does not have the shader fix installed for sun and bloom effects which makes a big improvement to the look more like the LB version. This would just require copying the existing lens_flare_offset.bin in to the common folder, but if it…

    iirc the 4th board/video bd. cyber cycles tends to have the video bd broken.

  • the project is done and it works to some extend. if you just have one broken card, there's nothing you can do about it. you need a donor card, which, i guess, if you don't have one, it's better buy a new and working one. the project useful, if you have multiple broken card, and you need to know which chip is good and which not. so, you can swap them and make a working one.

  • having 28 ohm only takes less than 200mA, which i guess it is pretty normal.

  • just have a time to do the burning, and the game boot, i put a more clear jumper setting pict here for reference. arcade-projects.com/forums/ind…aed4423305660eeed4a6dccb7

  • Something like these? they're used occasionally in monitor chassis and some pcb as an add on. the one i found is from digikey. but i am looking for cheap one from china, i.e. aliexpress? have tried but no luck, maybe different keyword. many thanks

  • searching it in google with "sega fd1094" showed some other sources.

  • sorry, i forgot to mention that it's for new one, not used one.

    i don't think the large chip at the center of the board is gpu, but most of time, that chip is the culprit. in some cases, pressing that chip by finger while it's on, the game would boot, if not, it just showing that kind of random led behavior. there's must be something wrong when reflowing the chip. as the burn smell, it could be worse, breaking another chip. your best bet would be just find another working one.

  • Quote from Finisterre: “After tearing my gun down, and simply removing the old "holder" or "lens", I cleaned the sensor array with a Q-tip and alcohol as it was covered in black dust and small plastic chunks. The debris seemed to be the result of years of the gun banging on the holster, etc. After the alcohol dried, and I ensured there were not additional impurities on the sensor, I closed it all back up with the new lens. ” Be very, very careful when cleaning these sensor array. There are very …

Now I am stumble upon "Handle error" I guess to bypass this I will need the wiring diagram to connect the steering wheel pot (handle) to the JVS I/O pcb. Can anyone help? So far no luck with finding wiring for any Battle Gear machine. ” What you did, that it changed from "rack error" to "handle error"? i am facing same problem here. I test them in the cab and have checked all cables. Anybody can help with known…

    Quote from twistedsymphony: “ Previous owner covered these in black ducktape , but there's also a lot of cracking that was epoxied back together. This is good enough to keep the machine playing but this whole piece of plastic will need to be repoed. Obviously a huge piece of plastic like this would be difficult to replace, repairing it would be difficult as well since it's made from a clear purple acrylic. However it's a very simple shape which makes me think a new one could be made using a vacu…
